Is Minpaku or Ryokan Operation Possible in Ota Ward? The Three Systems of Special Zone Minpaku, New Minpaku Law, and Simple Lodging, and the Application Process
Ota Ward is the only ward among the 23 Tokyo wards that implements the National Strategic Special Zone Minpaku (Special Zone Minpaku). In addition to the New Minpaku Law (Residential Accommodation Business) and Ryokan Business (Simple Lodging), there are three gateways to the accommodation business.
However, under the ward’s additional ordinance, the New Minpaku Law cannot be operated in residential-only areas and industrial areas. Ryokan business is also in principle not permitted to be built in these areas, so the option used in other wards—"If ryokan business is not possible in a residential area, the New Minpaku Law can be notified"—does not exist in Ota Ward.
This article focuses on the requirements under the New Minpaku Law and simple lodging, and the process until the simple lodging permit is issued. Since the Special Zone Minpaku has requirements uniquely established by the ward, please confirm details such as minimum stay duration and target areas with the ward’s responsible office.
The regulatory information in this article is organized based on our confirmation with the health center and publicly available ward materials (as of August 2026).
Quick Reference Table of Ota Ward Minpaku and Ryokan Regulations
| Category | Item | Details |
|---|---|---|
| Ryokan Business (Simple Lodging) | Front Desk (Entrance Registry) | Not required |
| On-call Requirement | Within 10 minutes on foot | |
| Notification to Neighbors | Explanation meeting | |
| Key Exchange | Key box allowed | |
| New Minpaku Law (Residential Accommodation Business) | Ward’s additional ordinance | Not permitted in residential-only and industrial areas |
Differences among the Three Systems
The New Minpaku Law is a notification-based system with an annual limit of 180 days, Ryokan Business requires a permit with no limit on the number of days, and the Special Zone Minpaku is a ward-certified system where the 180-day limit of the New Minpaku Law does not apply but it must meet ward-specified requirements.
| System | Procedure | Annual Business Days | Residential-only/Industrial Areas |
|---|---|---|---|
| New Minpaku Law (Residential Accommodation Business) | Notification | Up to 180 days | Operation prohibited due to ward ordinance |
| Ryokan Business (Simple Lodging) | Permit | No limit | Principally cannot be built |
| Special Zone Minpaku | Ward certification | Exempt from 180-day limit | Confirm with the ward |
The Special Zone Minpaku also has designated target areas set by the ward. Whether properties in residential-only or industrial areas can be used depends on those designations. Please indicate the property address and confirm with the ward.
Requirements for Ryokan Business (Simple Lodging)
Ota Ward’s simple lodging does not require a front desk (entrance registry), and it allows a system where staff can arrive on foot within 10 minutes as well as key exchange using a key box. Notification to neighbors is by holding explanation meetings.
Additionally, at the time of our investigation, the following revisions to notification and operation were indicated.
| Item | Content of Revision |
|---|---|
| On-call Contact Personnel | At least 3 people |
| Notification Range to Neighbors | Expanded to 20 meters |
| Explanation Meetings | Mandatory to hold at least twice |
| Notification Bulletin Board | From A3 size to A2 size or larger |
| Garbage Collection | From once weekly to three times weekly |
All of these directly impact operational costs. To have three or more on-call personnel requires an organizational structure capable of scheduling, whether handled in-house or outsourced. Increasing garbage collection to three times per week also increases the cost of waste collection contracts for business-generated waste.
When these revisions apply, to which systems or facilities, could not be confirmed in this article’s research. Please check with the health center regarding the latest operations and application to existing facilities.
Process Until Simple Lodging Permit is Issued
When starting simple lodging in Ota Ward, the process from prior consultation with the health center to commencement of business proceeds as follows:
- Consult with the health center in advance
- Receive prior confirmation from the health center based on building plans
- Proceed with building confirmation application (at Ward’s Building Examination Division) and consultations regarding fire law inspections (at the jurisdictional fire department)
- Notify neighbors (host explanation meetings)
- Apply for ryokan business permit
- Undergo on-site inspection by the health center
- The health center director confirms with the fire department chief
- Permit issued and business starts
Notification to neighbors must be completed before submitting the permit application. If holding two or more explanation meetings becomes mandatory, sufficient time will be needed between the first announcement and the second meeting, so preparing these while proceeding with building and fire-related procedures in parallel can shorten the overall period.
When converting a residence for lodging use, the building confirmation stage will include consideration of the change of use and confirmation of compliance with the Building Standards Act and Fire Service Act. If construction is necessary, this stage’s duration becomes the most difficult to predict.
New Minpaku Law (Residential Accommodation Business): Areas Where Operation is Prohibited
Ota Ward’s additional ordinance restricts by area rather than by day of the week. Operation is prohibited in residential-only areas and industrial areas but allowed within the national 180-day limit in other areas. For owner-absent type, management by a residential accommodation management business is required.
The absence of day-of-week restrictions makes it easier to construct cash flow compared with wards limiting operation to weekends or specific days like Friday-Saturday. However, if a residential area with many detached houses falls under a residential-only zone, the New Minpaku Law is excluded from candidates at that point. Please check the zoning on urban planning maps when searching for properties.
Property Market in Ota Ward (August 2026)
| Indicator | Ota Ward | Ranking among 23 Wards |
|---|---|---|
| Listed Detached House Median Price | 75,350,000 yen (154 listings, total floor area 93 m²) | 13th highest out of 21 wards |
| Rental Detached House Median Asking Rent | 220,000 yen/month (130 listings, 77 m²) | 10th highest out of 21 wards |
| Whole Building Income Property Gross Yield (Median) | 4.9% (107 listings) | 9th highest out of 23 wards |

Ota Ward’s listed detached house prices are slightly below the median among the 23 wards, and the number of listings is high. For those buying detached houses to use for whole-building rentals, it provides a favorable environment where acquisition costs can be kept low and options compared easily. Rental detached house asking rents are mid-level among wards, so the rent burden for subleasing types is not as heavy as in central wards.
The gross yield on income buildings is relatively high among the 23 wards. Since a certain yield can be expected even with regular rental, when choosing accommodation business you should compare whether the revenue after subtracting costs for explanation meetings, on-call personnel, and garbage collection exceeds rental income.
Checkpoints When Considering Properties in Ota Ward
- Check the zoning. Minpaku under the New Minpaku Law and ryokan business cannot be used in residential-only or industrial zones. Confirm whether the property falls within the Special Zone Minpaku target area by consulting the ward.
- For simple lodging, confirm if you can secure at least three on-call personnel capable of arriving within 10 minutes on foot.
- Assuming holding two or more explanation meetings, identify in advance the dwellings within the 20-meter notification range and the meeting venue.
- If garbage collection frequency increases to three times weekly, include the cost of collection contracts in fixed costs when calculating expenses.
- For condominium units, verify through management rules that minpaku or ryokan business is not prohibited. For rental properties, confirm and obtain the landlord’s written consent for subleasing and use.
Because Ota Ward has multiple system options, the optimal system varies depending on the zoning and scale of the property. How to organize operations including on-call systems, cleaning, and garbage collection is introduced on the Minpaku Management Service page.
Frequently Asked Questions
Can I file a notification under the New Minpaku Law for a detached house located in a residential neighborhood in Ota Ward?
If the property is located in a residential-only zone, operation is prohibited under the ward’s additional ordinance. If outside residential-only zones, operation is possible year-round within the 180-day limit regardless of day of the week. Please check urban planning maps for zoning.
Which should I choose, Special Zone Minpaku or the New Minpaku Law?
Special Zone Minpaku is not subject to the 180-day limit of the New Minpaku Law, but must satisfy requirements set by the ward (minimum stay days, target areas, etc.). Decide after confirming with the ward office both requirements based on the property location and expected length of guest stays.
Can I operate simple lodging in Ota Ward using a key box?
Key exchange using a key box is allowed. However, an on-call system to arrive within 10 minutes on foot is necessary, and at the time of our investigation, the placement of three or more contact persons was also indicated.
