August 1945: Japan's 'Strategy of Absence'—What the Binary Choice of Preserving the National Polity Obscured

In August 1945, the Imperial Conference narrowed its agenda to the feasibility of 'preserving the national polity' and 'unconditional surrender.' However, what was needed at that very moment was a concrete design for 'strategizing the defeat'—handling the Soviet front, evacuating civilians, securing humanitarian corridors, and establishing unified guidelines for surrender. This paper will clarify from the perspective of the regime why strategy was not discussed and provide a comprehensive overview of what was left undecided on the ground in Manchuria, Karafuto, the Kuril Islands, and northern Korea.

Chapter 1: Problem Statement—The 'Things Not Decided' at the End of the War

1-1 Background: Acceptance was decided, but the 'how to end it' was a blank slate

In August 1945, the Imperial Conference, Japan's highest decision-making body, finally decided to accept the Potsdam Declaration. However, the practical design for ending the war that should have become inevitable from that moment on—namely, handling the Soviet front, evacuating civilians, setting up humanitarian corridors, procedures for disarmament, and unified guidelines on which Allied forces to surrender to—fell outside the scope of the agenda. The concern of this paper is not the pros and cons of surrender or the personal qualities of the leaders, but rather why the
design of the conference and the structure of the national system failed to produce a consensus on practical strategy.

1-2 Hypothesis of this paper

• Hypothesis A: The Imperial Conference narrowed the agenda to a binary choice of value judgments between 'preserving the national polity' and 'unconditional surrender,' and did not function as a forum for handling operations (the implementation of the end of the war).

• Hypothesis B: Behind this lay structural flaws, specifically the separation of supreme command (military) and administrative power (political), and the triple structure of the Imperial Court, the Cabinet, and the Imperial General Headquarters, which meant that a circuit to unify the highest-level practical commands (withdrawal, surrender, transport) was institutionally missing.

• Hypothesis C: This void translated into concrete costs in each theater of war, namely Manchuria, northern Korea, Karafuto, and the Kuril Islands, such as delayed evacuations, complex surrender situations, expanded internment, and chaos at ports.

1-3 Specific items that the Imperial Conference 'did not decide'

The decision to accept was made. However, the following were not codified or given unified instructions (or did not reach the front lines).

1. Operational principles for the Soviet front

   • 'Total cessation' or 'limited delay for the purpose of civilian evacuation (buying time)'?

   • Drawing the line on how much discretion to allow for on-site judgment.

2. Unified Guidelines for Surrender Acceptance

   • Should priority be given to handing over to the US, UK, and China as much as possible, or should there be uniform compliance with the nearest Soviet forces?

   • From the perspective of avoiding internment, the priority order of handover countries should have been clearly defined.

3. Civilian Protection and Humanitarian Corridor Design

   • Priority slots for ports (sea routes) and railways (land routes), and agreements to protect minimum functions of medical, communication, and administrative services as 'non-military designated'.

   • Priority order for evacuation (children, women, the sick, and personnel) and covering rules for combat units.

4. Unified Protocol for Disarmament and Identification

   • Weapon stockpiling, identification insignia at the time of surrender, and the demarcation of non-combatant zones at ports and stations.

   • External procedures to note and notify these to the Allied side as well.

5. Unification of Command and Control (Provisional Inspector General for 'Withdrawal, Surrender, and Humanitarian Affairs')

   • Establishment of a provisional headquarters to issue integrated instructions for the implementation of the end of the war (consolidating transport, order maintenance, and external liaison).

   • A design to concentrate appointment/dismissal authority and the power to make exceptional decisions here to suppress inconsistencies in the field.

1-4 Overall Overview: How the Void Was Visualized

In the time period immediately before and after the end of the war, the front against the Soviet Union was moving as follows (details in the following chapter).

• Manchuria: The Kwantung Army collapsed rapidly due to deep and multi-axis offensives. Complications in surrender acceptance and increased internment.

• Northern Korea: Landing and military administration proceeded rapidly, and the window for southward evacuation closed in a short time.

• Karafuto: Amidst the early prohibition of movement off the island and chaos at ports, the unification of policies to maximize evacuation was delayed.

• Kuril Islands: The prior instructions for decentralized evacuation and sailing were not institutionalized, leading to confrontation with intensified local warfare.

These indicate that the explicit definition of priorities regarding 'what to protect and what to abandon' and the simultaneous parallel operation of command, transport, and external communication were exactly what was needed immediately after acceptance.

1-5 Why the agenda narrowed (presenting only the location of the problem)

This paper does not delve into leadership theory. Here, I will only indicate the location of the systemic aspects. Detailed description in Chapter V.

• Institutional factors: Due to the separation of supreme command (military) and administrative power (political), the function to draft an integrated political and military strategy was institutionally weak.

• Power Configuration: The triple structure of the Imperial Court, Cabinet, and Imperial General Headquarters obscured the locus of ultimate responsibility. The Imperial Conference was more of a ritual for confirming consensus and was ill-suited for introducing new proposals.

• Information and Time Factors: Under the sudden shock of the atomic bombings and the Soviet entry into the war, the agenda ballooned into 'to accept or not to accept', while the organization of prerequisites for practical implementation was relegated to the background.

1-6 Summary of this chapter

The Supreme Council regarding the end of the war succeeded in resolving value judgments (national polity vs. acceptance), but time passed without deciding on the practical design for ending the war—such as the operation of the front against the Soviet Union, protection of civilians, humanitarian corridors, surrender locations, disarmament procedures, and the unification of command and control.
From the next chapter onward, this paper will show how this vacuum manifested as concrete costs in each theater (Manchuria, Northern Korea, Sakhalin, and the Kuril Islands), and in Chapter V, it will converge on the systemic flaws (separation of command and administration, triple power structure, and ritualized conference operations).
To anticipate the conclusion, ending a war is an act of deciding 'how to end it' at the same time as 'stopping it'. The Imperial Conference accomplished the former, but failed to accomplish the latter as a system.

Chapter 2: What is the Imperial Conference? — System, Participants, and Procedures

2-1 Positioning: An Extra-Legal 'Final Approval Mechanism'

The Imperial Conference (Gozen Kaigi) is not a permanent institution under written law. It is a customary conference for the leaders of the government (Cabinet) and the Imperial General Headquarters (Army and Navy High Command) to meet in the presence of the Emperor to give final approval to major national policies.
Practically speaking, it was a 'place of approval' to 'raise' and finally confirm and sanction policy proposals that had been worked out at lower levels, and it was not in its nature to spend long hours debating new, detailed designs there.

2-2 Participants: Fixed Members of the Core

The composition in the summer of 1945 was generally as follows (other relevant cabinet ministers joined as necessary).

• The Emperor

• Cabinet: Prime Minister (Kantarō Suzuki), Foreign Minister (Shigenori Tōgō), and others

• Military: Minister of War (Korechika Anami), Minister of the Navy (Mitsumasa Yonai), Chief of the Army General Staff (Yoshijirō Umezu), Chief of the Naval General Staff (Soemu Toyoda)

• Privy Council Relations: President of the Privy Council (Kiichirō Hiranuma) and others

• Key Imperial Court Officials: Close aides responsible for internal reports and liaison (such as Koichi Kido). These 'three government members (Prime Minister, Foreign Minister, and Military Minister) plus two military commanders (Chiefs of the Army and Navy General Staff)'
  core six membersconstituted the substantive decision-making unit during the war (commonly known as the 'Big Six'), and the Imperial Conference was placed as an extension of this.

2-3 Until the Agenda is Raised: The Pipeline of Submission

Raw issues did not 'suddenly' appear at the Imperial Conference.It was standard procedure for drafts and options to be refined in advance by lower-level bodies such as the 'Imperial General Headquarters-Government Liaison Conference' or the 'Supreme Council for the Direction of the War,' for the proposals from the Cabinet, Foreign Ministry, and military command to be unified, for the Privy Council to review the legal form (draft imperial rescripts and instructions), and then for final approval to be received at the Imperial Conference.For this reason, the Imperial Conference tended to become a place to
decide the 'yea or nay' of proposals raised from belowand was fundamentally ill-suited for the task ofcreating implementation (operational) theories from scratch.

2-4 Operating Principles: Consensus and the 'Sacred Decision'

The operation of the Imperial Conference was governed by two principles.

1. Consensus-Oriented
   Participants were fundamentally not there toexhaustively debate opposing views, but to confirmagreements prepared in advance. Long, technical deliberations were not conducted.

2. Sacred Decision (Break the Tie)
   If opinions remained divided, theEmperor's expression of will (Sacred Decision) became the final 'deciding factor'. This was used twice in August 1945, bringing a resolution to the value judgment regardingwhether or not to accept the terms.

2-5 The Two Imperial Conferences of August 1945 (The Reality of Their Functions)

• First Conference (August 9–10): Centered on the acceptance of the Potsdam Declaration (whether or not to attach conditions regarding the national polity), withpros and cons evenly matched. Ultimately, the policy of acceptance was decided bySacred Decision.

• Second Meeting (August 14): Final confirmation of acceptance based on the Allied response. Although conflict remained here as well, it was settled by another Imperial decision. In both cases,
  the meeting time was spent on the decision-making of value preferences—'to accept or not to accept', and the framework of practical strategies such as handling the anti-Soviet front, civilian evacuation, humanitarian corridors, and unified guidelines for surrender like the framework of practical strategies was not concretized at the Imperial Conference table.

2-6 Why practical strategies are difficult to raise (structural reasons)

• Separation of command authority and administrative power: Military operational guidance was the exclusive jurisdiction of the Imperial General Headquarters, and the design was not set up for politics (the Cabinet) and the military (command) to work out implementation plans at the same table.

• 'Meeting of meetings' structure: Drafts were formed in lower-level meetings, and the Imperial Conference was the top-level approval mechanism. Integrated practical tasks (withdrawal, transport, surrender, external coordination) could not be designed without establishing a separate, temporary integrated headquarters.

• Constraints of time and psychology: Due to the shock of the atomic bombings and the Soviet entry into the war, the agenda converged on the 'pros and cons of acceptance.' The practicalities of 'how to end it' were put on the back burner.

2-7 Summary of this chapter

The Imperial Conference was a conventional institution that was strong in final approval of value judgments but weak in designing practical strategies in nature. The two meetings in August 1945 typically demonstrate this character. In the next chapter, we will visualize how this institutional character failed to mesh with
the actual battlefield environment (Manchuria, Northern Korea, Karafuto, Kuril Islands)—how the window for evacuation closed, and what happened because certain things were not decided—using a theater-by-theater timeline.

Chapter 3: The Reality of August—The Overall Picture of the Anti-Soviet Front (Manchuria, Northern Korea, Karafuto, Kuril Islands)

3-1 Overview of the entire front (August 9 to early September)

In August 1945, the Soviet Union deployed simultaneously on four fronts: Manchuria (main front), Northern Korea, Karafuto, and the Kuril Islands. Simultaneous with the entry into the war against Japan on August 9, they began a multi-axis, high-speed invasion (the so-called 'August Storm'), and thereafter, repeatedly conducted maritime maneuvers and coastal landings, cutting off Japanese evacuation routes one after another. (Army University Press)

3-2 Manchuria: Multi-axis Blitzkrieg and Collapse

• Nature of the operation: The three fronts—Transbaikal, 1st Far Eastern, and 2nd Far Eastern—advanced simultaneously from the periphery to the depth. They forced their way through railway junctions and river crossings, pressuring the rear and flanks of the Kwantung Army simultaneously. (Army University Press)

• Tempo: Started on August 9. The main defensive lines were breached in a short period, and the collapse of command spread rapidly. Even in operational studies (US Army CSI/Glantz), it is summarized as "strategic success in the shortest possible time". (Army University Press)

• Implications: It was necessary to "to whom and where to surrender" (unifying the handover destination) and procedures to avoid internment to be clearly defined on all fronts immediately after acceptance. In reality, the policy was not unified, and local surrender and disarmament became chaotic. (Wikipedia)

3-3 Northern Korea: Successive Landings and the Acceleration of Military Government

• Barrage of coastal landings: August 11–13 at Unggi (present-day Sonbong) and Rajin, and August 13–16 at Chongjin ("Chongjin Operation"), naval infantry and others landed successively. While cutting off the Japanese military's retreat from the rear, they seized railways and ports. (Wikipedia)

• Incursion into the interior: August 24, Soviet forces entered Pyongyang. Thereafter, the establishment of a military government system north of the 38th parallel proceeded. (Wikipedia)

• Implication: A unified directive prioritizing evacuation southward from the north (via rail) and the designation of humanitarian corridors were necessary within the first 48 hours after acceptance. The delay directly resulted in a narrowing of the window for movement.

3-4 Karafuto (Sakhalin): Invasion, Port Chaos, and the 'Ban on Leaving the Island' of August 23

• Operational Progress: Started August 11—until the 25th. After breaching the border, forces entered ports and cities such as Maoka and Korsakov. (Wikipedia)

• Blocking of Evacuation: On August 23, the Soviet side issued a decree 'banning departure from the island'. By then, emergency evacuation had been partially achieved, but on the 22nd, three evacuation ships were sunk, resulting in approximately 1,700 deaths (Sansen Junan Incident). Full-scale postwar repatriation reached a total of approximately 280,000 people between late 1946 and the summer of 1949. (Wikipedia)

• Supplementary Lines from Primary Sources: Japanese official documents and surveys reveal a scale of 'planned repatriation of approximately 80,000 people'. Additionally, it is estimated that approximately 25,000 people escaped via clandestine travel between August 1945 and September 1946, which the Soviet side strictly suppressed. (city.bibai.hokkaido.jp)

• Implication: Because a nationwide uniform protocol for humanitarian corridors—such as port priority quotas, evacuation order, and the demarcation of non-combatant zones—was missing, it led to confusion and a concentration of casualties based on on-site decisions.

3-5 Kuril Islands: The Assault on Shumshu and Chain Occupation

• Battle of Shumshu: August 18–23, Soviet forces launched an amphibious assault on Shumshu. Both sides suffered heavy casualties, and it is considered the only battle where Soviet casualties exceeded those of the Japanese. Later, all of the Kuril Islands were occupied by September 5. (ibiblio.org)

• Implication: By institutionalizing measures such as the aforementioned dispersed evacuation and the rotation of small craft, the scope for early withdrawal of island residents and personnel should have been expanded, but no unified design existed.

3-6 External Conditions (Minimal Summary)

On August 16, Stalin requested that the U.S. include the 'northern half of Hokkaido (north of the Kushiro-Rumoi line)' in the Soviet surrender acceptance zone, but Truman rejected this on the 18th. As for the external environment, the Soviet occupation of Hokkaido was deterred, but for the local handling of Karafuto, the Kurils, northern Korea, and Manchuria, Japan's own 'end-of-war implementation' was essential. (Office of the Historian)

3-7 Summary of this Chapter—The 'Window' was Short, and the 'Corridor' was Undesigned

• Window of Time: Due to the blitzkrieg in Manchuria and the barrage of coastal landings, the time window for evacuation was compressed to just over ten days. (Army University Press)

• Undesigned Corridor: Humanitarian corridors for ports and railways, unification of surrender acceptance points, disarmament and identification procedures, and centralized withdrawal and transport command—the fact that these were not promptly unified in design after the Imperial Conference led directly to confusion, casualties, and expanded internment in each theater. (Wikipedia)

Chapter 4: The Costs Created by 'What Was Not Decided'—Visualizing Theater-Specific Timelines

4-1 Five Undecided Items × Theater Symptoms (Correspondence Table)

Undecided Items: Manchuria, Northern Korea, Karafuto, Kuril Islands

1. Operational principles for the Soviet front * (Total cessation or delay for civilian evacuation cover)

   • Local judgment dispersed before multi-axis breakthroughs. Cessation/delay/self-defense combat mixed, units lacked coordination, leading to increased encirclement and internment

   • Between coastal landings and inland advances, explicit instructions prioritizing southward movement were not thoroughly implemented, causing regional variations in train operation and evacuation priority

   • Resistance under the pretext of evacuation cover and thorough ceasefire ran in parallel at ports and cities, concentrating chaos and casualties at ports

   • Decisions on resistance/evacuation split by island, leading to localized combat without the institutionalization of prior dispersed evacuation

2. Unified guidelines for surrender

   • (To which Allied power, and in what order)

   • Field negotiations were delayed due to confusion over where to hand over control. As a result, the flow of mass surrenders to the Soviet side, leading to internment, was reinforced.

   • Guidelines for movement to the south (US military lines) were weak, and surrenders in the northern regions took precedence.

   • Restrictions on movement off the islands arose early, leaving little room to choose where to surrender.

   • In places like Shumshu, the cycle of combat, occupation, and surrender occurred in such a short period that the room for choice was minimized.

3. Design of Humanitarian Corridors

   • (Priority slots for ports and railways, evacuation order)

   • Humanitarian priority slots for railways and transit hubs were invisible, leaving the distinction between military and civilian use to local discretion

   • The priority sequence for humanitarian trains from the north to the south was ambiguous, causing the window for movement to shrink

   • Non-combat zones at ports, concentrated allocation of shipping capacity, and evacuation priorities were not standardized, leading to congestion and casualties at ports

   • Rotational operation of small vessels and route designations were missing, preventing early evacuation from functioning as a system

4. Disarmament and Identification Protocols

   • (Handling of stockpiles, insignia, and ports/stations)

   • Weak standardization of weapon stockpile locations and insignia led to dangerous encounters

   • Delays in demarcating non-combat zones at train stations fueled public disorder

   • Low visibility of ceasefire identification at ports kept tensions high

   • Stockpile and identification procedures on islands varied by location, causing disparities in surrender processing speeds

5. Unification of Command and Control

   • (Unified Command for Withdrawal, Transport, and Surrender)

   • Lines of operations, administration, and transport were fragmented, leading to uneven arrival order and speed of orders

   • Absence of a unified command for southward operations, resulting in reliance on local coordination

   • Port operations (who decides)lacked unification, causing delays in decision-making

   • Left to self-help for each island, with no unified scheme in operation

4-2 'Narrowing of the Window' Viewed on a Time Axis (Outline)

• 8/9–12 (First Wave)
  Manchuria: Start of deep penetration. Northern Korea: Coastal landings ahead.
  → 'Where to withdraw to' should have been clearly stated as the first window.

• 8/13–18 (Second Wave)
  Northern Korea: Successive landings in Chongjin and elsewhere, inland advance. Kuril Islands: Pre-stage of Shumshu.
  → A window to secure humanitarian priority slots for railways and ports that should have been fixed.

• 8/19–25 (Third Wave)
  Northern Korea: Advance into Pyongyang. Sakhalin: Port combat and prohibition of movement off the island. Kuril Islands: Battle of Shumshu.
  → The final window to finalize the last evacuation flights and decentralized rotation.

4-3 Three Bottlenecks That Appeared on the Ground

1. Lack of a single directive
   Because there was no foundational sentence stating "prioritize civilian protection; military action limited to delay," the line between ceasefire/covering fire became fragmented at each location.

2. Lack of a corridor map
   The absence of a "corridor specification document" detailing priority allocation of ports and railways, demarcation of non-combat zones, and priority order for evacuation targets induced congestion and conflict.

3. Lack of a unified command
   There was no provisional integrated command to bundle withdrawal, transport, surrender, and external communication, causing the speed and order of command transmission to become chaotic across theaters.

4-4 Common Patterns of Symptoms (Across Theaters)

• "Ports and railways will be the first to be blocked."
  Without corridor specifications, a chain reaction occurs: port congestion leading to increased attack risk / railway bottlenecks leading to abandoned evacuations.

• "Confusion at surrender points increases 'internment'."
  Unless the priority for handover is clearly stated, handover at the nearest location will take precedence, and the risk of post-war detention will skyrocket.

• "Strict punishment for minor errors / ambiguity for major errors" is the worst combination.
  The workarounds devised by small-scale sites on their own are corrected after the fact, while the overarching strategic design remains undecided—a reversal of priorities.

4-5 Summary of this chapter: What the 'absence of operations' brought about

• The five practical items that the Imperial Conference failed to decide manifested within the short time window of August in Manchuria, Northern Korea, Karafuto, and the Kuril Islands as delayed evacuations, surrender confusion, increased internment, and port chaos.

• The common cause lies in the fact that simplification of objectives (humanitarianism first), pre-definition of corridors, and unification of integrated command—the minimum necessary specifications—never came down from above as a system.

Chapter 5: Why No Strategy Was Formed—An Anatomy of Systemic Factors

5-1 Constitutional Structure: The Separation of Supreme Command and Administrative Power

• System Design

  • Under the Constitution of the Empire of Japan, supreme command (operational guidance) belonged to the Emperor's prerogative and was assisted by the General Staff Office and the Naval General Staff, while administration (politics, diplomacy, and finance) was under the jurisdiction of the Cabinet.

  • As a result, a space for institutionally creating 'strategy (the integration of politics and military)' was prone to being left vacant.

• Consequence

  • Even if the value judgment of accepting the end of the war was decided at the Imperial Conference, the demarcation of stopping operations / the integration of withdrawal and transport / the guidance of surrender acceptance locations and other such implementations were left in limbo between 'supreme command or administration'.

5-2 Triple Power Structure: The Overlap of the Imperial Court, Cabinet, and Imperial General Headquarters

• The Actual Power Map

  • The Imperial Court (Lord Keeper of the Privy Seal/close aides), the Cabinet (Foreign Ministry/various ministries), and Imperial General Headquarters (Army/Navy)—these three poles overlapped with one another, yet decision-making authority remained ambiguous.

• Impact on Meeting Operations

  • The Imperial Conference was closer to a ritual for 'sanctioning' a consensus prepared in advance, and it lacked the capacity to refine new practical proposals on the spot.

  • 'Who has final responsibility and what is being decided' was scattered, and 'not deciding' tended to be the choice with the least friction.

5-3 Vertical Dual Systems: The Army/Navy General Staffs and the Army/Navy Ministries

• Dual Line

  • Army: General Staff (Operations) — Ministry of War (Personnel/Logistics)

  • Navy: Naval General Staff (Operations) — Ministry of the Navy (Personnel/Logistics)

• Missing Elements

  • The Joint Staff function was weak, preventing cross-coordination between the Army and Navy, and between operations and administration.

  • As a result, 'withdrawal = operations,' 'transport = administration,' and 'surrender = diplomacy + security' operated separately, making a simultaneous, parallel design impossible.

5-4 The Limits of Deliberative Bodies: The 'Coordinationism' of the Liaison Conference / Supreme Council for the Direction of the War

• Preliminary Meetings

  • The Imperial General Headquarters-Government Liaison Conference / Supreme Council for the Direction of the War specialized in coordinating the opinions of each organization and drafting policy proposals.

• Submission to the Imperial Conference

  • The value judgment draft of 'accept/not accept'prepared here is submitted, but it is unclear who is drafting the 'specifications' for withdrawal, surrender, and corridors.

  • If one attempts to include specifications, the issue of the boundary between command and administrationis touched upon, causing resistance, so the agenda itself thins out.

5-5 Command and Communication Mechanisms: Lack of Unified Distribution

• Lack of a 'distribution entity' rather than communication speed

  • Even if the Imperial Rescript on the Termination of the War and ceasefire notices are issued, the standing protocol for 'who, with which seal, and in what order of priority to distribute simultaneously nationwide' is weak.

• Field Results

  • Ceasefire/self-defense combat/civilian protection interpretations of the wording variedwidely, resulting in time lags and mutual contradictions.

  • Disarmament and identification procedures (insignia/assembly points) were also difficult to unify due to divided jurisdictions.

5-6 Priority of Values: The Inflation of National Polity Preservation and the Marginalization of Practical Affairs

• Bias in Agenda

  • Under the shock of the atomic bombings and the Soviet entry into the war, the pros and cons of 'preserving the national polity/unconditional surrender' inflated into the sole political issue.

• Oversight

  • At that moment, non-heroic but effective agendas that were fundamentally necessary, such as 'humanitarian priorities' and 'designing evacuation corridors', were pushed outside the conference culture.

5-7 Disconnect Between Diplomacy and Military: The Uncoupling of External Leverage

• Structural Division

  • Foreign Ministry diplomatic negotiations and Imperial General Headquarters' operational and ceasefire management were not mutually constrained at the same table.

• Loss of Opportunity

  • International confirmation of humanitarian corridors (ports, railways, emblems) and external coordination such as directing surrender locations (prioritizing the U.S. and China if possible) could not be integrated into domestic operational instructions.

5-8 Summary of Systems and Operations: Capable of Decision-Making, but Unable to Create Implementation

• Consequences of the System

  • The Imperial Conference was suitable for final approval of value judgments, but it was not a mechanism for designing and ordering the implementation of the end of the war (withdrawal, surrender, corridors, identification, and unified command).

• Ripple Effects on the Ground

  • That void was visualized as the complexity of surrender acceptance and increased internment in Manchuria, the delay in the southward advance in northern Korea, the chaos at ports and the stagnation of evacuations in Karafuto and the Kuril Islands (see Chapters 3 and 4).

5-9 Conclusion of this chapter

While the Imperial Conference on ending the war decided on the act of 'ending it' itself, the institutional circuit to decide 'how to end it' was missing from the start. That omission stemmed from

1. the structural separation of command and administration,

2. the diffusion of responsibility due to the triple structure of the Imperial Court, the Cabinet, and the Imperial General Headquarters,

3. the fragility of the integration function that bundles operations, administration, and diplomacy,

4. the operation of meetings that had become mere approval rituals, which derived from
   systemic problems. Therefore, even though the Imperial Conference could sanction
   the pros and cons of ending the war, it could not produce a design for ending the war—this is the subject of this paper. In the next chapter (the final chapter), based on this systemic defect, I will list the 'minimal practical tasks that Japan could have decided' (at the item level) and conclude this paper.

Chapter 6: The Minimal Practical Tasks That Could Still Have Been 'Decided' at the Time—Conclusion

6-1 Design Philosophy: Codify the Three Principles (within 48 hours)

• Principle 1: Humanitarianism First
  At the beginning of the nationwide notification, clearly state in one sentence that 'the protection of civilians and the maintenance of medical and communication services are the highest priorities.'

• Principle 2: The Military's Role is Limited to Delaying Actions
  'Combat is limited to covering civilian evacuation. Offense and retaliation are prohibited.' Standardize the interpretation of the ceasefire order nationwide.

• Principle 3: Surrender Must Be Orderly and Rapid
  In regions where possible, prioritize non-Soviet surrender (US/China), and in other areas, hand over to the Soviets using a standardized protocol. Present the priority order for surrender destinations on a single sheet of paper.

6-2 Command and Control: Temporary Integrated Command for 'Withdrawal, Surrender, and Humanitarianism' (Today to 24 hours)

• Name and Jurisdiction: Temporary 'End-of-War Implementation Headquarters'. Unify and direct withdrawal, transport, surrender, and external communication.

• Authority: Exclusive power to simultaneously issue Army/Navy operations, transport (ministry), and foreign ministry external notifications under the headquarters' name.

• Personnel Selection: Cross-departmental placement of vice-ministerial level officials from the Army, Navy, Foreign Ministry, Railways, and Home Ministry (no individual charisma required; coordinating the administrative windows of the offices).

• Distribution Protocol: Multiplexing of encryption, radio, wire, official gazettes, and press telegrams, and mandatory receipt confirmation (read/resend).

6-3 Humanitarian Corridor: Visualizing the 'specifications' of ports and railways (24–48 hours)

• Ports:

  • Type 1 (Highest Priority): Clearly designate evacuation-only, non-combat zones; prohibit the lingering of disarmed personnel.

  • Type 2 (Auxiliary): For small vessels and coastal routes. Disperse and rotate to extract personnel.

  • Standardize ceasefire identification (flags/lights) and inspection flow across the country for use within ports.

• Railways:

  • Humanitarian slots (women, children, the sick, medical personnel) fixed by time and formation.

  • Lower the priority of military trains and clear tracks in the direction of the corridor.

• Evacuation priority: (1) Children (2) Women (3) The sick (4) Medical/communications personnel (5) Others. Nationally standardized vocabulary used for codification.

• Ceasefire map: Non-combat zones at ports, stations, and roads, and evacuation routes plotted on a single map and distributed to local government offices.

6-4 Acceptance of surrender/disarmament: A single-page document for avoiding conflict (48–72 hours)

• Guidelines for Surrender:

  • First Priority: Handover to the U.S. military and the Chinese Nationalist Government.

  • Second Priority: For unavoidable regions, hand over to the Soviet military and standardize the procedures.

• Standardization of Procedures (Example):

  1. Assembly points and times (ports, stations, plazas)

  2. Identification marks(white cloth, armbands, flags) types and placement

  3. Order of disarmament (ammunition → firearms → melee weapons)

  4. Formation of officers, non-commissioned officers, and enlisted men, and roll call forms

  5. Minimum necessary medical and communicationexempt items

• Prohibited acts: Destruction of facilities, concealment of supplies, and conscription of residents are prohibited uniformly nationwide. Violations will result in immediate punishment (sentencing in the following section).

6-5 'Institutionalization' of Rewards and Punishments: Limited only to appointments, dismissals, and sentencing (to be announced within 72 hours)

• Appointments and Dismissals:

  • Commanders and local officials who achieved results in evacuation and maintaining order are to be immediately promoted and commended.

  • For violations of orders (private warfare, looting, destruction), immediate removal from office.

• Sentencing Guidelines (Simplified Code):

  • Severe punishment: Looting, destruction, violence against residents, resumption of hostilities.

  • Intermediate: Failure to follow orders, private requisition → demotion or suspension.

  • Light punishment: Errors in field judgment → reprimand (however, in case of recurrence, move to intermediate).

• Transparency: Rewards should be publicized, punishments should be concise. Clearly state that this is for the maintenance of order, not based on emotion.

6-6 External Notification: Issue in tandem with domestic specifications (parallel processing)

• To the US and China: Notify them of humanitarian slots for ports and railways and ceasefire identification, and request avoidance of accidental fire on routes and vehicles.

• To the Soviet Union: Notify them of demarcation of non-military zones, disarmament procedures, and humanitarian priority quotas. Mutually declare not to interfere with transportation.

• Public Communiqué: Announce the three points of protection of civilians, maintenance of the ceasefire, and order for accepting surrender using the same wording both domestically and internationally.

6-7 Operational Plan Aligned with the 'Window' (Guidelines)

• Day 0–2 (Acceptance to 48h): Notification of the three principles / Establishment of the Headquarters for Implementing the End of the War / Notification of port and railway specifications.

• Day 3–7: Activation of humanitarian slots / Decentralized evacuation (islands and coastal areas) / Commencement of surrender protocol operations.

• Week 2: Clearing port congestion and accelerating railway southward movement / Connecting to full-scale postwar repatriation schemes (Foreign and Welfare Ministries).

6-8 Expected Effects and Limitations (An Honest Accounting)

• Effects:

  • Reduction of congestion at ports and stations, increase in the number of evacuees, suppression of clashes and accidental fire, gradual reduction of detention (guiding to surrender points).

• Limitations:

  • External constraints such as the Red Army's operational tempo in Manchuria and the ban on leaving the island in Karafuto are significant. The goal is not a miraculous reversal, but the mitigation of damage.

6-9 Conclusion—The Failure Was the Inability to 'Design' the End of the War

The Imperial Conference decided to end the war. However, it failed to produce as a system the practical design for how to end it—prioritizing humanitarianism, establishing corridors, organizing surrender acceptance, and coordinating nationwide action through identification and unified command—as a functional framework. Behind this lay

• the separation of supreme command and administrative authority,

• the triple structure of the Imperial Court, the Cabinet, and the Imperial General Headquarters,

The 'end-of-war implementation package' presented in this paper is the minimum required set of actions that could have been decided within 48 hours without revolutionizing the system. It is not the right or wrong of the defeat, but the absence of a design for defeat that manifested as delayed evacuations, chaotic surrender acceptance, increased internment, and port congestion in each theater—this is where I place the conclusion of this paper.
Ending a war is not about 'stopping' but about 'designing'. The lack of such a blueprint was, in itself, the greatest failure.

Conclusion

What this paper has shown is that while the Imperial Conference of August 1945 could authorize the end of the war, it could not design as a nation how to end it. Ending a war is a design, not a decision—this obvious requirement was not met due to institutional reasons. What remained unresolved were five items: (1) operational principles for the front against the Soviet Union, (2) unified guidelines for surrender acceptance, (3) humanitarian corridors for ports and railways, (4) disarmament and identification protocols, and (5) a unified command to bundle withdrawal, transport, and surrender acceptance. The absence of these manifested concretely as the confusion and internment during the surrender in Manchuria, the delay in the southward advance in northern Korea, and the port congestion in Karafuto and the Kuril Islands. This paper focuses on the defects of the system and conference operations, rather than on personal character or value judgments. Figures for evacuation, repatriation, and internment vary across sources, and details regarding ports and railway stations still require further verification. The counterfactual analysis is limited to the minimum operational specifications that could have been communicated within 48 hours and does not assume any miraculous reversal. Similar comparisons can be found in Germany in 1918, Italy in 1943, and Finland in 1940/44. In all cases, the three points of humanitarian corridors, identification, and unified command are key, and the 'implementation' of ending a war is a challenge of the same nature regardless of the country. To repeat the conclusion: the Imperial Conference decided the 'whether' but did not decide the 'how' of the practical work. Ending a war is a design, and the absence of a blueprint was the greatest cause of increased casualties in every theater. This single point is a lesson worth taking beyond the bounds of history.
