Functions and Features of the Automated Important Matters Explanation Check Tool
We have started pre-orders for our Important Matters Explanation check tool, which is, of course, a tool that performs checks automatically.
You should leverage the parts where human memory and experience are valuable, while also
taking advantage of the tool's strengths, such as the AI, proprietary prompts, and uniquely designed features it is equipped with.
And you should strive to ensure that this leads to more secure and safer transactions.
There is information suggesting that 30% to 40% of troubles in the real estate industry are caused by the Important Matters Explanation document.
For example, take the security deposit settlement trouble in lease agreements, which has been a long-standing issue and is a representative type of trouble in the real estate industry.
Even in 2026, this remains a very common issue, but it is possible to reduce the number of such troubles if you understand how to properly create an Important Matters Explanation document.
However, even in 2026, security deposit settlement troubles remain frequent.
This may be proof that real estate companies that have not yet encountered such troubles have been viewing them as someone else's problem.
It may be that many real estate companies are using Important Matters Explanation documents that are merely templates from various associations with the blanks filled in, or documents finished to an equivalent level.
However, when trouble occurs, it can place a heavy burden on both the employees of the real estate company and the tenants (customers).
Real estate troubles can affect both parties' families as well.
The attitude of striving to minimize the probability of such troubles not only helps in preventing them but also serves as an opportunity to increase the sense of security and trust from your customers.
This tool is recommended for business efficiency, reducing labor costs, improving the quality of employee checks, learning purposes for inexperienced new employees, agents new to the real estate industry, those starting a new business without real estate experience, and landlords who handle contract work themselves.
I hope that finding this article will be the catalyst for you to
consider introducing the Important Matters Explanation check tool.
If you have circumstances that prevent immediate adoption, I would be happy if you could at least keep in mind that such an Important Matters Explanation check tool exists.
Introduction to the functions of the (automated) Important Matters Explanation check tool
Check Accuracy and Comprehensiveness
Check function for all 370 items
Checks the entire structure of the Important Matters Explanation, including property identification, rights relations, legal restrictions, infrastructure, road access, boundaries, area, building condition, facilities, management, management association finances, charges, special provisions, notification matters, contract conditions, cancellation conditions, damages, and IT-based explanations.
■ Examples of the number of check items by transaction pattern
・Lease x Condominium unit x Tenant (simplest)
Approximately 80-100 items checked
・Lease x Condominium unit x Tenant x Tokyo
Approximately 120-140 items checked
・Sales x Detached house x Buyer x Kanto
Approximately 130-150 items checked
・Sales x Condominium unit x Full protection x Tokyo (most complex) Approximately 180-200 items checked
Checks completed in 6-7 minutes with 5-phase automatic execution
Automatically executes 5 stages in succession: RED/YELLOW check -> Diagnosis/Legal scan -> Regional custom check -> 2nd AI independent inspection.
Completed with a single operation.
(*Since regional customs cannot be fully grasped, only some customs are subject to checking)
Prompts developed by licensed real estate notaries
Check criteria from a practitioner's perspective, covering the Real Estate Brokerage Act Articles 35 and 37, the Civil Code, the Consumer Contract Act, and the latest judicial precedents.
Check function for all 280 items
Checks performed with the perspective of a judge considering whether it will function as evidence in court.
Implements original prompts capable of wide-ranging checks impossible with free AI chats.
Real-time legal information retrieval
Although it is a tool that uses AI,
when using either Claude or Gemini, the AI performs its own web searches during the check to obtain the latest information from the Ministry of Land, Infrastructure, Transport and Tourism, the All Japan Real Estate Federation, the Consumer Affairs Agency, and the courts (ChatGPT is supplemented with RSS information injection).
Support by Regional Custom and Perspective
Equipped with Regional Custom Modules
Supports 13 regions nationwide from Hokkaido to Okinawa, plus forest and rural areas.
Independently checks region-specific business customs and checkpoints in a dedicated phase.
5 Perspective-Based Protection Modes
A function that switches check priorities according to the respective positions of real estate companies, sellers, buyers, lessors, and lessees. Supports both BtoB and BtoC.
Visibility and Ease of Use of Results
Instant Visual Recognition with RED/YELLOW/GREEN
Displays check results in color blocks by severity.
RED = Immediate correction required, YELLOW = Improvement recommended, GREEN = No issues. You can also grasp the number of items at a glance.
Includes Ready-to-Copy Correction Text
Automatically generates "correction text ready for immediate use in the field" for RED/YELLOW findings.
Displays legal grounds, articles, and precedents simultaneously.
Quality Evaluation (A-D) by Second AI
A second AI, independent of the first, checks for oversights and misjudgments.
Displays quality evaluation from A to D to ensure reliability.
2-AI Interactive Cross-Check Function
It is also possible to have the same important matter explanation checked twice by different AIs, such as Claude and Gemini, and automatically compare the differences.
Effective for double-checking high-value or important cases.
(*Cross-checking using two types of AI, or even using the same AI, provides a cross-check effect.)
Operational Efficiency
Supports File Loading
Supports drag-and-drop for PDF (text-based), Word (.docx/.doc), and text (.txt) files. Pasting is also possible.
The specifications allow for checking photographed important matter explanations, but there are cases where the tool cannot read them, such as when the text is faint or has unique fonts.
Dispute Probability and Damage Risk Diagnosis (19 Perspectives)
Automatically diagnoses dispute risk after checking.
Identifies in advance matters that may become points of contention in court, such as "I didn't know" or "I wasn't told."
Check History and Template Saving
Automatically saves up to 15 check histories in the browser.
Allows registration of frequently used condition sets (rental, Tokyo, condominium, real estate company, etc.) as templates.
Printing, PDF Output, and Text Saving
Can be printed or output as a PDF as a check report.
Supports full-text copying and text downloading.
Safe and Secure Design
API Keys Kept Only Within the Browser
API keys are not sent to the server.
Designed to be kept only in the browser's memory.
No Learning Usage via API
Claude API and ChatGPT API are not used for learning by default according to their specifications. Important matter explanations containing personal information can be processed safely. (The same applies to the paid Gemini tier. Use of the free Gemini tier is prohibited as it is used for learning.)
Differentiation Points
Includes prompts designed by licensed real estate notaries based on practical experience
Checks with the depth of "Important Matter Explanation-specific" rather than "General-purpose AI"
Comprehensive risk coverage based on actual cases using the 37 Trouble Catalog
Regional custom checks as an independent dedicated phase
A dual-verification mechanism featuring independent inspection by a secondary AI
Corrected text is output in a ready-to-copy-and-paste format
