A detailed guide to the procedures for turning a home in Japan into a minpaku in 2026: mansion requirements, mandatory equipment, management costs, and a realistic profit-and-loss simulation.
Owning a detached house or condominium in Japan is a proud milestone for many Vietnamese families, engineers, and working residents who have settled there. However, many families need to return to Vietnam to visit relatives for several weeks or even months, or have one or two unused rooms. Turning this vacant space into a minpaku (民泊 — short-term, Airbnb-style accommodation) to earn extra passive income can be extremely appealing.
That said, running accommodation in Japan is not simply a matter of “cleaning the house and uploading photos online.” You will face a host of strict legal regulations, restrictions imposed by building management associations, the cost of installing fire-prevention and firefighting systems, and the ongoing challenge of operating expenses. This article by OlaChill’s editorial team will give you a complete overview of the requirements, procedures, and realistic financial considerations involved in legally turning your home into a minpaku in Japan.
1. What Is Minpaku? Two Common Operating Models in Japan
The minpaku system was officially legalized under the Residential Accommodation Business Act — 住宅宿泊事業法 (jutaku shukuhaku jigyo ho), also known as the New Minpaku Act. Under this law, homeowners can rent out their homes to short-term visitors for a maximum of 180 nights/year (calculated from 1/4 of this year to 1/4 of the following year).
Depending on whether you live with your guests, the law divides minpaku operations into two main models:
Type 1: Owner-occupied — 家主居住型 (yanushi kyoju gata)
- Features: The owner lives in the apartment throughout the guests’ stay (typically renting out a spare room in the home).
- Procedures & Costs: Fire-safety requirements are less demanding, and because the owner handles guest check-in and management personally, hiring an outside management company is not mandatory.
Type 2: Owner absent — 家主不在型 (yanushi fuzai gata)
- Features: You rent out the entire house/apartment while you are away (on a business trip or visiting Vietnam), or the property has no owner living there.
- Procedures & Costs: Requirements are much stricter. Under the law, if the owner is absent or the property has more than 5 rooms available for rent, the owner must appoint a licensed residential accommodation management company — 住宅宿泊管理業者 (jutaku shukuhaku kanri gyosha) — to operate the property.
2. The Biggest Obstacle for Mansion Condominiums: Building Rules 管理規約 (kanri kiyaku)
If you own a detached house (一戸建て - ikodate), registering a minpaku mainly depends on local government regulations. However, if your home is a condominium (Mansion - マンション), the biggest obstacle is the building management association — 管理組合 (kanri kumiai).
According to statistics from major cities such as Tokyo and Osaka, as of August 2026, more than 90% of condominium buildings clearly state in their building management rules — 管理規約 (kanri kiyaku) that using units for minpaku or short-term accommodation is prohibited. This is because local residents are concerned about noise, waste, and security.
- Required step before starting the procedure: You must check the building’s 管理規約 (kanri kiyaku).
- If the rules prohibit it: You absolutely cannot register a legal minpaku.
- If the rules do not clearly state either way: You must obtain written confirmation from the management association (管理組合 - kanri kumiai) proving that the building does not prohibit minpaku operations. If you operate secretly and are discovered, you may face administrative penalties, lose listing access on platforms such as Airbnb/Booking, and seriously affect your residency records in Japan.
3. Neighbor Notification and Permit Procedures (August 2026)
If the property meets the legal requirements and the building allows minpaku operations, you must complete the registration process according to the standard steps in effect as of August 2026:
Step 1: Explain the plan and notify neighbors — 近隣への説明 (kinrin he no setsumei)
Many wards and municipalities in Tokyo, Kyoto, and Osaka require homeowners to send notification letters or hold an explanatory meeting for households within the prescribed radius (typically neighboring units, as well as those directly above and below) before submitting the application. The notification must include an emergency contact phone number to use in the event of an incident.
Step 2: Prepare the legal documentation
The documents submitted to the Minpaku Portal — 民泊ポータルサイト (minpaku potaru saito) or the local Public Health Center — 保健所 (hokenjo) include:
- Real estate registration certificate: 登記事項証明書 (toki jiko shomeisho).
- Floor plan of the property: 住宅の平面図 (jutaku no heimeizu) — clearly showing the locations of the kitchen, toilets, bathroom, firefighting equipment, and bedroom floor areas.
- Fire-safety compliance certificate: 消防法令適合通知書 (shobo horei tekigo tuchisho), issued by the Fire Department (消防署 - shobosho) after an on-site inspection.
- Proof of identity and residence: 住民票 (juminhyo) of the homeowner.
- Property management authorization agreement: (If operating under the 主人不在型 - owner-absent model).
4. Mandatory Equipment and Safety & Fire-Prevention Systems
To meet minpaku standards, the property must have 4 basic residential amenities: a kitchen, toilet, bathroom, and balcony/washing facilities. In addition, the minimum bedroom area must be 3,3 m² / guest.
Fire-safety regulations — 消防設備 (shobo setsubi) — are also strictly enforced:
- Fire extinguisher: 消火器 (shokaki), placed in an easily visible location.
- Smoke detector / automatic fire alarm: 自動火災報知設備 (jido kasai hochi setsubi). Condominiums and multi-story homes are often required to install an interconnected alarm system.
- Emergency lighting: 非常用照明設備 (hijoyo shomei setsubi), installed along passageways and staircases so it operates during a power outage.
- Evacuation route map: 避難経路図 (hinan keirozu), posted by the room entrance in multiple languages (Japanese, English, Vietnamese/Chinese).
- Guest accommodation guide: Guests must be given instructions on sorting waste, the rule against making noise after 22h, and the emergency phone numbers 119/110.
5. Operating Costs, Cleaning, and Management Company Fees
When you are not at home to clean the property and welcome guests yourself, you need to carefully calculate the monthly expenses involved.
Detailed Minpaku Operating Cost Breakdown (As of August 2026)
(Reference exchange rate as of August 2026: 1 JPY ≈ 165 VND)
| Expense item | Details & Average cost (Yen) | Estimated conversion (~VND) | Notes |
|---|---|---|---|
| Management company fee (住宅宿泊管理業者) | 15% – 20% / of net revenue | ~15% – 20% of revenue | Mandatory for the owner-absent model. |
| Platform commission (Airbnb / Booking) | 3% – 15% / per booking | Depends on the OTA’s policy | Deducted directly from each booking. |
| Cleaning & laundry fee (清掃費) | 7.000 ¥ – 15.000 ¥ / per stay | ~1,15 – 2,48 million VND / per stay | Usually charged to guests as a cleaning fee. |
| Electricity, water, internet, and gas | 20.000 ¥ – 35.000 ¥ / month | ~3,3 – 5,78 million VND / month | Tourists typically use more electricity and heating than a household. |
| Depreciation & consumables | 5.000 ¥ – 10.000 ¥ / month | ~825.000 – 1,65 million VND / month | Restocking shampoo and toilet paper, and replacing damaged towels. |
| Fixed asset tax (固定資産税) | Calculated annually | Depends on the property value | A fixed annual cost regardless of whether the property is rented out. |
6. Simulated Revenue and Realistic Profit & Loss
Suppose you own a 2LDK detached house near a station in the suburbs of Tokyo or Osaka. You set aside 120 days/year (within the 180-day limit) to operate it as a minpaku while you are away or during peak travel seasons.
Business Assumptions (As of August 2026)
- Average nightly rate: 18.000 JPY (~2,97 million VND).
- Occupancy rate: 70% of the 120 available days = 84 nights/year (an average of 7 nights/month).
- Total gross annual revenue: 18.000 JPY × 84 nights = 1.512.000 JPY (~249,48 million VND).
Annual Income and Expenses
1. Gross Revenue: 1.512.000 JPY (~249,5 million VND)
2. Airbnb platform fee (estimated at 3%): -45.360 JPY (~7,5 million VND)
3. Management company fee (20% of net revenue): -293.328 JPY (~48,4 million VND)
4. Electricity, water, and internet (12 months): -240.000 JPY (~39,6 million VND)
5. Annual fire-equipment inspection/maintenance: -30.000 JPY (~4,95 million VND)
--------------------------------------------------------------------------------
=> AFTER OPERATING EXPENSES:
Profit before tax (Net Profit): ~903.312 JPY / year (~149 million VND)
(An average of approximately ~75.000 JPY / month, equivalent to ~12,4 million VND/month)
(Note: The cleaning fee 清掃費 is paid separately by guests through the app, so it offsets the actual cost of hiring a cleaning service).
Practical assessment: If you operate a minpaku to help cover your mortgage payments (住宅ローン - jutaku ron) while you are away, a profit of 75.000 JPY/month is highly meaningful. However, if you view it as a get-rich-quick investment, the 180 days/year limit and strict management costs make it difficult for the return to outperform a traditional long-term rental.
7. Frequently Asked Questions
Q. Can I operate a minpaku in a home I am still paying off with a mortgage (住宅ローン - jutaku ron)?
Answer: Most banks in Japan offer preferential 住宅ローン (jutaku ron) packages on the condition that the property is used as YOUR primary residence. If you convert the property entirely to minpaku operations, the bank may require you to switch to a business loan, which carries a much higher interest rate. However, if you operate under 家主居住型 (living with guests and renting out a spare room) or only offer short-term rentals while you are away, you should consult your lending bank before registering.
Q. Can I clean the property myself to save on the cleaning fee (清掃費)?
Answer: Yes, if you operate under the owner-occupied model (家主居住型 - yanushi kyoju gata). However, if you operate under the owner-absent model (家主不在型) and have authorized a management company (住宅宿泊管理業者), the company will generally handle the cleaning or set professional cleaning standards to ensure tourist-accommodation hygiene standards are met.
Q. Who is responsible if neighbors complain about noise or waste caused by minpaku guests?
Answer: Under the New Minpaku Act, if you operate under the owner-absent model, the appointed management company must be able to arrive at the property within 10-30 minutes (depending on local regulations) to address neighbors’ complaints. If the problems recur repeatedly, the authorities may revoke the property’s minpaku license.
Conclusion
Turning a home you already own into a minpaku is a smart way for Vietnamese residents in Japan to make better use of their assets and generate additional passive income while they are away. However, Japan’s legal procedures require complete compliance—from checking the building’s 管理規約 (kanri kiyaku), to obtaining a fire-safety certificate, to hiring a legally authorized management company. Carefully calculate the potential profit and loss, and prepare all the necessary documents before you begin operating.
