Dental Practice Startup: Financing with 300,000 Yen in Personal Funds | Practical 5-Layer Full Design [2026 Edition]
I only have 300,000 yen in personal funds on hand right now.
I confessed those words to a colleague from my days as a salaried doctor on the way home after viewing a potential property for my practice.
When you add up the property, chair units, CT scanner, sterilizer, electronic medical records, interior design, and operating capital, the total investment is on the scale of 50 million yen.
The reality staring me in the face was that I had no choice but to secure almost full financing for it.
Perhaps you are standing in the same situation.
This article focuses specifically on the concrete situation of having only 300,000 yen in personal funds, and organizes how to stack five funding sources—Welfare and Medical Service Agency (WAM), Japan Finance Corporation, bank proprietary loans, leasing, and installment payments—including credit information from your time as a salaried doctor and the design of pre-opening operating capital (as of June 2026).

Key Points of This Article
A dental startup with 300,000 yen in personal funds is designed on the premise of a 5-layer full financing structure, treating it as 'near-zero personal funds'.
The Welfare and Medical Service Agency (WAM) clinic loan offers 24 million yen unsecured with a 1-year deferment, which can be combined with the Japan Finance Corporation's startup loan as a two-stage rocket.
Leasing and installment payments should be used selectively for each piece of equipment to level out monthly burdens and preserve pre-opening operating capital.
Taking steps to organize your credit information (credit cards, card loans, student loans) from your time as a salaried doctor starting six months in advance significantly impacts the loan approval rate.
This article is a guide to a 5-layer design calculated backward from the 'extreme premise of 300,000 yen in personal funds' that higher-level articles do not touch upon.
What the premise of 300,000 yen in personal funds means
You must design your plan on the premise that 300,000 yen in personal funds is 'close to zero personal funds'.
According to the Japan Finance Corporation's '2024 Survey on New Business Startups,' the average loan amount at the time of opening is 7.8 million yen (65.2% of the total funding), and the average personal fund amount is 2.8 million yen.
There is a misunderstanding that many readers have here.
It is the idea that 'even with only 300,000 yen in personal funds, a total of 50 million yen will be granted in a lump sum based on clinical experience and future earnings.'
However, the reality is the opposite.
It is difficult to secure a 50 million yen dental startup loan in a single financing package, even if you have 5 to 10 million yen in personal funds.
Even more so with only 300,000 yen in personal funds, a multi-layered design that combines five funding sources to reach 50 million yen is the only realistic solution.
Many dentists who have successfully opened their practices have been building up their personal funds and cleaning up their credit history in parallel starting one year before opening.
Breakdown of a 50 Million Yen Dental Startup and the 5-Layer Funding Map
The basic design is to break down the 50 million yen into 'equipment, interior, and operating funds' and apply the optimal funding source to each.
The total investment of 50 million yen for a dental startup is roughly broken down into the following ratios.
Property acquisition/security deposit … 3 to 5 million yen
Interior/facility construction … 12 to 18 million yen
Chair units (2-3 units) … 8 to 12 million yen
CT/panoramic diagnostic imaging equipment … 8 to 15 million yen
Sterilizers, small instruments, electronic medical records … 3 to 5 million yen
Pre-opening operating funds (personnel costs, rent, advertising) … 5 to 8 million yen
In contrast, the 5-layer funding sources that can be designed based on 300,000 yen in personal funds are as follows.
1. Welfare and Medical Service Agency (WAM) Clinic Loan
Role: Main pillar of startup funding (long-term funds for land, buildings, and large equipment)
Estimated Limit: Publicly stated as available up to 24 million yen for unsecured portions
Term: Up to 20 years (including a 1-year deferment period)
Strengths: Stable interest rate levels as a public financial institution, and specialized screening criteria for medical institutions
Weaknesses: 2 to 4 months from application to execution, and a heavy burden of document preparation
2. Japan Finance Corporation (New Startup Loan)
Role: A second pillar to run alongside WAM, or for advance procurement when WAM cannot meet the timeline
Estimated Limit: 15 to 20 million yen is a realistic target for a startup dental practice
Term: 15 years for equipment, 7 years for working capital (2-year deferment)
Strengths: Relaxed personal fund requirements and extensive expertise in screening for startups
Weaknesses: Difficult to fully cover 50 million yen on its own
3. Bank Proper Loans (Regional Banks/Credit Unions)
Role: A supplementary framework to fill the gap left by WAM/JFC, or a flexible framework for working capital
Estimated Limit: 5 to 15 million yen depending on the individual practitioner's credit and projected earnings
Strengths: Allows for early establishment of a main bank relationship after opening
Weaknesses: Pure proper loans generally require 3 terms of stable profit; for startups, loans with Credit Guarantee Association backing or bank business loans with guarantee companies are more realistic
4. Leasing (Large equipment such as chair units and CT scanners)
Role: Deferring equipment ownership and leveling costs as monthly working capital
Term ... 5 to 7 years is standard
Strengths ... Initial cash outflow can be kept near zero; plans including maintenance are also available
Weaknesses ... Total payment is 10-20% higher than a loan; early termination is generally not possible
5. Installment Plans (for small to medium equipment such as sterilizers, small instruments, and electronic medical records)
Role ... Installment purchase of individual equipment; ownership eventually transfers to you
Term ... 3 to 5 years is standard
Strengths ... Total payment is lower than leasing, and ownership is transferred
Weaknesses ... Consumes credit limits from credit companies, which can tighten limits when handling multiple projects
These five layers complement each other.
Establish the main pillar with WAM, build a second pillar with the JFC, secure a flexible operating fund line with a bank, level out large equipment costs with leasing, and finely distribute small equipment costs with installment plans.
Why the Welfare and Medical Service Agency (WAM) is strong for 300,000 yen in personal funds
WAM's clinic loans are the 'first public funding source to consider' for practitioners with limited personal funds.
The Welfare and Medical Service Agency (WAM) is an independent administrative institution under the Ministry of Health, Labour and Welfare that provides policy-based financing specialized for medical and welfare facilities.
There are three key points regarding 'medical loans' that can be used as startup capital for dental clinics.
The first is that an unsecured limit of up to 24 million yen is set.
Considering that JFC startup loans typically land in the 15 to 20 million yen range for unsecured amounts, WAM alone allows for higher unsecured procurement than the JFC.
The second is that a deferment period of one year is guaranteed.
Opening a dental clinic is not a business where patient numbers stabilize from the very first month.
Since insurance claim payments are deposited two months after the month of treatment, the first deposit after opening will not arrive until the third month.
During the deferment period, principal repayment is waived, which creates significant leeway in cash flow during the startup phase.
The third point is the fact that interest rate levels are publicly stable.
WAM interest rates are determined based on the interest rates of fiscal loan funds and are positioned at a lower level compared to bank-proprietary loans or business loans with guarantee companies.
Assuming a long-term repayment period of 20 years for the practice, a 1% difference in interest rates results in a difference of several million yen in the total payment amount.
Note that WAM screening takes 2 to 4 months from application to execution, so starting 6 months before opening is a realistic schedule.
Two-Stage Rocket Design: JFC and WAM
The "two-stage rocket" approach, which uses both WAM and JFC, is the most efficient way to design a startup with 300,000 yen in personal funds.
It is not realistic to secure 50 million yen through WAM alone or JFC alone.
By running both in parallel, you can leverage the strengths of each.
The first step is to begin preparations for the WAM application 6 months before opening.
Gather your business plan, tenant information for potential practice locations, quotes (for chair units, CT, and interior work), withholding tax slips from your time as an employed doctor, and a list of household assets and liabilities.
Since it takes time from application to execution, you should work backward from this point.
The second step is to apply for a JFC startup loan 3 months before opening.
JFC has a faster execution speed than WAM, with the process from application to execution taking 1 to 2 months.
If you apply for JFC while having secured the main pillar of funding through WAM, it becomes easier to convey the story to the screening officer that "WAM has already approved, and the remaining amount is for JFC."
The third step is to cultivate relationships with banks for proprietary loans or business loans with guarantee companies after the execution of WAM and JFC loans.
Build relationships with regional banks and credit unions once you have accumulated 3 to 6 months of performance data after opening.
The important thing here is not to expect a bank-direct loan from the start.
In the startup phase, it is realistic to use loans guaranteed by the Credit Guarantee Corporation or bank business loans guaranteed by non-bank private guarantee companies (such as Orico or Credit Saison).
This structure, where the bank is the lender and the non-bank company provides the guarantee, has an increasing number of products available for startups and functions as a supplementary route after exhausting the JFC and WAM limits.
As a way to run this in parallel, using a matching service that allows you to apply to multiple banks simultaneously can reduce the time spent visiting each bank yourself.
Leveling out monthly burdens with leases and installment plans
The standard practice is to use leases for large equipment like chair units and CT scanners, and installment plans for smaller equipment like sterilizers and electronic medical record systems.
Leasing and installment plans are similar but distinct procurement methods.
The strength of a lease is that the leasing company retains ownership of the equipment, allowing you to keep initial cash outflow at almost zero.
Because it is leveled into a monthly lease fee, you can preserve your pre-opening operating funds.
If you set up an 8 million yen chair unit on a 5-year lease, the monthly burden will generally be in the 140,000 to 150,000 yen range.
This stays within a range that does not overly pressure your repayment sources for JFC and WAM loans.
On the other hand, the strength of an installment plan is that ownership eventually transfers to you, and the total payment amount is 10-20% cheaper than a lease.
For equipment with a medium unit price, such as sterilizers (300,000 to 500,000 yen) and electronic medical record systems (2 to 4 million yen), it is efficient to set them up with 3 to 5-year installment plans.
There are common pitfalls here.
The first is purchasing all equipment at once with a loan.
If you try to buy all equipment using JFC/WAM loan limits for a 50 million yen scale dental startup, your operating fund limit will shrink.
Considering the risk of continued deficits from the first month of opening, the standard approach is to convert equipment costs into monthly payments via leases or installments and secure a thick cash buffer for operating funds.
The second is underestimating the total monthly lease amount.
When you add up the lease fees for 5 years and 10 units, the monthly cost can sometimes reach 500,000 to 800,000 yen.
Given that receipt payments are delayed by two months, a simulation that ensures monthly lease payments do not strain your working capital is essential.

Credit information from your time as an employed doctor influences loan approval rates
Taking steps to organize your credit information 6 months before opening significantly determines the success or failure of loan approval.
Because dentists have high income levels during their time as employed doctors, they are a demographic that easily passes screenings for credit cards, card loans, and mortgages.
However, the flip side of this is that there are cases where they have damaged their credit information without realizing it.
There are 4 points you should check before opening your practice.
1. Number of credit cards held and usage limits
Verification … Perform credit information disclosure via CIC/JICC
Risk … If you hold 10 or more cards, the total credit limit is too high, which is a negative factor in the evaluation for new loans
Action … Cancel unused cards at least 6 months before opening
2. Outstanding balances on card loans and cash advances
Verification … Understand the total of your outstanding balances and contract limits
Risk … If there is an outstanding balance, it will be deducted from the requested amount for your business opening loan
Action … Pay off in full by 3 months before opening and proceed to cancellation
3. Scholarship repayment status
Verification ... Repayment history of Japan Student Services Organization (JASSO) loans
Risk ... If delinquency history remains on your credit report, it will definitely be checked during the loan screening process
Response ... If there is a history of past delinquency, disclose the circumstances and current repayment status at the time of application
4. Status of mortgage and auto loans
Verification ... Outstanding balance and monthly repayment amount
Risk ... If the repayment burden of existing loans is high, the evaluation of the repayment source for the business opening loan will decrease
Response ... Consider options to reduce the monthly burden through refinancing or early repayment
These four points can be grasped within one hour by requesting a credit information disclosure (CIC/JICC, approximately 1,000 yen online for each company).
A realistic schedule is to request disclosure 6 months before opening, identify issues, and rectify them by 3 months before opening.
How to accumulate operating funds before opening
Operating funds should be based on '6 months of fixed costs for opening' and incorporated into the framework of the Japan Finance Corporation (JFC) and WAM.
Operating funds for a dental practice are a cash reserve to support the 'start-up period' from the first month of opening until receipt payments stabilize.
The start-up period is usually 3 to 6 months.
The total amount of fixed costs during this period (rent, personnel costs for hygienists and receptionists, lease fees, utilities, advertising expenses, and your own living expenses) is the guideline for operating funds.
The first point is not to cut operating funds from the equipment and interior budget .
Out of a total investment of 50 million yen, it is standard to secure an operating fund framework of 5 to 8 million yen.
If you cut this to spend on equipment and interiors, the possibility of a cash shortfall in the third month of opening will increase dramatically.
The second point is to explicitly incorporate operating funds into the JFC startup loan .
JFC startup loans allow you to combine both equipment funds and working capital into a single loan.
By clearly specifying the breakdown in your business plan, such as '6 million yen for working capital and 14 million yen for equipment funds,' it becomes easier to secure the working capital quota.
The third point is to prepare to secure a flexible working capital line through bank business loans after opening before you even open.
Once you have 3 to 6 months of operating results, explore regional banks, credit unions, and bank business loans with credit guarantees to prepare a flexible working capital line (5 to 10 million yen).
This is not meant to be used at the time of opening, but rather secured as an 'insurance policy' that you hopefully won't need to use.
6-Month Preparation Schedule Starting with 300,000 Yen in Personal Funds
The success rate of an opening plan with 300,000 yen in personal funds is determined by the arrangements made 6 months in advance.
Here are the actions you can take starting six months before opening, organized by month.
6 Months Before Opening — Disclosure and Organization of Credit Information
Request credit information disclosure from CIC and JICC
Cancel credit cards and confirm outstanding balances on card loans
Compare tenant information for 3 to 5 potential opening locations
Begin preparing application documents for WAM and JFC
Select a certified support agency and a tax accountant specializing in dental practice openings
5 Months Before Opening — Full-Scale Preparation for WAM Application
Create a business plan (sales forecast, profit and loss plan, and cash flow statement)
Obtain quotes for chair units, CT, and interior work (from at least 3 companies)
Increase personal funds (aim to grow from 300,000 yen on hand to over 1 million yen)
4 Months Before Opening — Executing the WAM Application
Submitting Application Documents to WAM
Starting Preparation of Application Documents for JFC
Preliminary Consultations with Banks (Regional Banks/Credit Unions)
3 Months Before Opening — Executing the JFC Application
Applying for JFC Startup Financing
Requesting Quotes from Leasing and Credit Companies
Final Adjustments for Tenant Lease Agreement
2 Months Before Opening — Leasing and Installment Contracts
Confirming Execution of WAM and JFC Loans
Signing Leasing and Installment Contracts
Commencement of Interior Construction
1 Month Before Opening — Final Stages of Opening Preparation
Delivery and Installation of Equipment
Staff Recruitment and Training
Preparing Applications for Bank Business Loans (Flexible Working Capital Lines)
By advancing this 6-month schedule, it becomes possible to realize a dental practice opening on a 50-million-yen scale, even under the extreme premise of having only 300,000 yen in personal funds.
As a strategy to run in parallel, we also recommend a service called Taskari, which compares and proposes bank business loans suited to you.
In parallel with the JFC and WAM screening processes, you can list candidates for flexible working capital lines for after you open.
Three Execution Principles for Building from 300,000 Yen in Personal Funds
We will consolidate the design for a dental practice startup with 300,000 yen in personal funds into three principles.
The first is to design with a 5-layer full financing structure.
Instead of trying to secure 50 million yen through a single loan, we combine WAM, JFC, banks, leasing, and installment plans, utilizing the strengths of each.
The second is to apply with a time lag using a two-stage rocket approach with WAM and JFC.
By applying to WAM six months before opening and JFC three months before, you can secure your primary and secondary pillars along a timeline.
The third is to prepare your credit information and operating funds six months in advance.
While cleaning up credit cards and remaining debts from your time as an employed doctor, explicitly incorporate 5 to 8 million yen in operating funds into your financing framework.
If you align these three elements, even with the extreme premise of only 300,000 yen in personal funds, a concrete path toward a 50-million-yen-scale dental practice startup becomes visible.
Frequently Asked Questions
Is it really possible to get financing for a dental practice startup with only 300,000 yen in personal funds?
It is possible. However, this does not mean you get 50 million yen with only 300,000 yen; it is based on the premise of building up by combining the five layers of WAM, JFC, banks, leasing, and installment plans. If the accuracy of your business plan, your clinical track record as an employed doctor, the state of your credit information, and the patient acquisition prospects of your chosen location are all in order, there are examples of people who have realized a startup with less than 1 million yen in personal funds. Conversely, if even one of these elements is missing, there are cases where screening becomes strict even with 10 million yen in personal funds.
Which should I apply to first, WAM or JFC?
WAM comes first. There are two reasons. First, WAM's screening takes a long time, 2 to 4 months, and if the application timing is delayed, you will not make it in time for the opening date. Second, if you apply to JFC with your primary pillar already approved by WAM, the story that 'it is already approved by WAM and we are seeking the remainder from JFC' is easily conveyed to the screening officer, which tends to make it easier to pass the JFC screening as well.
If my annual income as an employed doctor was high, do I not need to worry about my credit information?
You do need to worry. The higher your income bracket, the more likely you are to hold numerous credit cards, card loans, and mortgages, and having a total credit limit that is too high can negatively affect your loan screening. It is standard practice to request a credit information disclosure from CIC and JICC six months before opening and to proceed with canceling unused cards and paying off remaining debts.
How should I distinguish between leasing and installment plans?
Distinguish based on the unit price of the equipment and your intention to own it. Large equipment such as chair units (3 to 5 million yen per unit) and CT scanners (5 to 10 million yen) are suited for leasing, which can bring initial cash outflow close to zero. Medium-sized equipment such as sterilizers (300,000 to 500,000 yen) and electronic medical record systems (2 to 4 million yen) are suited for installment plans, where ownership is eventually transferred. Since the total payment amount is 10-20% higher for leasing, the basic decision axis is to use installment plans for equipment you strongly intend to own, and leasing for equipment where you want to prioritize leveling out monthly payments.
