Can You Operate Minpaku and Ryokan Businesses in Sumida Ward? Resident Staff Rules and Operating Day Restrictions Starting April 2026
In Sumida Ward, the revision scheduled to take effect on April 1, 2026, makes the presence of staff at the facility a key factor affecting the number of operating days. Facilities without resident staff can only operate from Friday noon to Sunday noon; they may not operate on weekdays.
For ryokan business (simplified lodging), the on-call requirement is “resident staff,” and keys must be handed over “directly face-to-face.” Facilities operating before the revision are exempt, so the main impact is on businesses starting after the revision.
Sumida Ward is not part of the National Strategic Special Zone Minpaku (short-term rental) area. The following information is current as of the time of research for this article; please check with the ward office for detailed provisions and transitional measures of the revision plans.
The regulatory information in this article is compiled by our company based on confirmation with the health center and publicly available ward documents (as of August 2026).
Summary Table of Minpaku and Ryokan Regulations in Sumida Ward
| Category | Item | Details |
|---|---|---|
| Ryokan Business (Simplified Lodging) | Front Desk (Entrance Reception) | None |
| On-call Requirement | Resident staff (with exclusive restroom/guest rooms) | |
| Notification to Neighbors | Explanation meeting | |
| Key Handover | Direct face-to-face | |
| New Minpaku Law (Residential Lodging Business) | Ward's Additional Ordinance | [Effective 2026/4/1] If no resident staff, operation limited to Friday noon to Sunday noon (no weekday operation). Existing facilities exempt. Front desk installation obligation added from 4/1. |
What Changed in the April 2026 Revision
The revised regulations established by the ward’s additional ordinance include the following three points.
- If there is no resident staff, operation is limited to Friday noon to Sunday noon only (no weekday operation)
- Existing facilities operating before the revision are exempt
- The obligation to install a front desk was added
From Friday noon to Sunday noon covers two nights: Friday stay and Saturday stay. On an annual basis, this limits operations to about 104 nights (52 weeks × 2 nights). Please check with the ward for how holidays on weekdays are handled.
The effective date of April 1, 2026 has already passed. However, the exact details regarding which system and which facilities the front desk installation obligation applies to, and the conditions for facilities to be treated as existing, have not been fully confirmed in this article. Please verify the latest enforcement status with the ward office along with this summary table.
Ryokan Business (Simplified Lodging): Resident Staff and Face-to-Face Key Handover Required
Ryokan business requires a permit system and there is no annual limit on operating days. In Sumida Ward, the on-call requirement is “resident staff,” and conditions regarding dedicated restrooms and guest rooms are also specified. Keys must be handed directly face-to-face to guests; unmanned check-in using key boxes is not assumed.
Please consult the health center at the blueprint stage regarding how to secure the resident staff’s location and restroom. Because a fixed area and personnel cost for resident staff are required, facilities with fewer guest rooms will face tougher revenue conditions.
Preapplication neighborhood notification involves two stages: signage installation and explanation meeting.
| Step | Details | Deadline |
|---|---|---|
| Signage Installation | Display advance notification signage (at least 60cm vertically and horizontally) | — |
| Notification to Health Center | Report signage installation using Regulation No. 11 form | Within 5 days of installation |
| Announcement of Explanation Meeting | Notify neighbors of the meeting | At least 5 days before the meeting |
| Explanation Meeting | Explain the plan to nearby residents | — |
The signage size requirement of at least 60cm by 60cm is larger than A3 size (approximately 42cm x 30cm), so signage used in other wards cannot be reused as is. The 5-day notification deadline after installation is easy to overlook, so it is advisable to prepare the notification form on the same day as signage installation to ensure compliance.
New Minpaku Law: If No Resident Staff, Only Friday and Saturday Stays Allowed
The New Minpaku Law is a notification system with a nationwide annual limit of 180 days. In Sumida Ward, due to the above revision, facilities without resident staff can only operate from Friday noon to Sunday noon. Owner-absent types must entrust management to a residential lodging management operator, and operating day restrictions apply on top of that.
| Operation Type | Operating Days Allowed | Annual Limit (Approx.) |
|---|---|---|
| Ryokan Business (Simplified Lodging) | Every day | 365 days |
| New Minpaku Law with Resident Staff | No ward weekday restrictions | 180 days |
| New Minpaku Law without Resident Staff | Friday noon to Sunday noon | About 104 days (52 weeks × 2 nights) |
| Existing Facilities from Before Revision | Not subject to revision | As per previous conditions |
The approx. 104 nights is the maximum allowed operating days; actual utilization would be lower. The reality is that it has become difficult to build a business using owner-absent minpaku as an investment in Sumida Ward after the revision.
Sumida Ward Property Market Conditions (August 2026)
| Indicator | Sumida Ward | Ranking Among 23 Wards |
|---|---|---|
| Listed Detached House Price (Median) | 62.8 million yen (64 listings, total floor area 90㎡) | 18th highest of 21 wards |
| Rental Detached House Asking Rent (Median) | 200,000 yen/month (26 listings, 73㎡) | 13th highest of 21 wards |
| Whole Building Income Property Gross Yield (Median) | 5.7% (67 listings) | 2nd highest of 23 wards |

Sumida Ward ranks relatively low in detached house listing prices among the 23 wards, making it easier to keep acquisition costs of whole-building minpaku down. Rental detached house rents are mid-range among the 23 wards, and fixed costs of subleasing are lighter than those in central wards.
The gross yield for whole-building income properties ranks high among the 23 wards, offering a certain level of expected return even with regular rentals. For lodging businesses, it is important to consider whether operating costs for resident staff and weekday restrictions allow you to exceed this rental yield. After the revision, comparing lodging business against holding as rental property is worthwhile.
Checkpoints When Considering Properties in Sumida Ward
- Confirm with the ward whether the property is subject to the revision (whether it will be treated as an existing facility or requires new notification/permit)
- Check if the floor plan can secure a place and exclusive restroom for resident staff
- For ryokan business, confirm the zoning. Ryokan and hotels cannot be built in residential-only or industrial zones, and are limited to under 3,000㎡ in Category 1 Exclusive Residential Zones
- Confirm whether there is a place to display signage at least 60cm by 60cm
- If converting from a residence, confirm whether change of use permission is required and estimate costs for compliance with Building Standards Act and Fire Service Act
- Check management rules for condominiums and sublease consent from landlords for rental properties
In revised Sumida Ward, whether a facility can be operated with resident staff is a key factor in choosing this kind of lodging business. For information on operational systems including arranging resident staff, please see the Minpaku Operation Agency page.
