Can Minpaku and Ryokan Operations Be Conducted in Minato Ward? Simple Lodging with Key Boxes and Prior Notice Starting 20 Days Before Application
Minato Ward is one of the 23 special wards where it is relatively easy to operate ryokan businesses (simple lodging) in a nearly unmanned manner. There is no requirement to install a front desk, and key handover by key boxes is acceptable. As long as there is a system to respond to troubles by arriving within approximately 10 minutes, it is not necessary to have a person stay at the facility.
However, the effort is required in prior neighbor relations before application. Since August 2020, it has been required to notify nearby residents in writing and display a plan signboard at least 20 days before applying. This 20-day period must be factored into the schedule from property handover to business commencement.
Under the Minpaku Law (Housing Accommodation Business Act), there are no special ward restrictions for host-resident minpaku, but host-absent minpaku have operating period restrictions depending on the area. Minato Ward is not designated as a National Strategic Special Zone minpaku implementation area.
The regulatory information in this article is organized based on our confirmation with the Health Center and publicly available ward materials (as of July 2026).

Ryokan Business (Simple Lodging): Condition for Unmanned Operation Is "Approximately 10 Minutes"
Ryokan businesses require permits, with no limit on the number of operating days per year. In Minato Ward, there is no obligation to install a front desk, and handover of keys via key boxes is permitted. What is required in addition is the arrangement to be able to reach the facility within approximately 10 minutes when contacted by guests.
According to confirmation with the Health Center, plans involving arriving by car are acceptable, but in such cases, a nearby parking lot or parking space at the property must be secured. If your management base is located at some distance from the facility and assumes traveling by car, please include securing parking as part of your operating costs.
Even if cleaning and emergency response are outsourced, it is advisable to confirm before contracting that the time from the contractor’s base to the facility meets this standard for response time.
Operations without a front desk must also handle guest identification and noise complaints as part of their response system. Decide in the entrusted contract who will respond to nighttime calls and who will travel to the facility.
Prior Notice Starting 20 Days Before Application
For ryokan business permit applications in Minato Ward, the following procedures must be completed before applying.
| Timing | Task | Submission to Health Center |
|---|---|---|
| At least 20 days before application | Install a plan signboard (A3 size) | Immediately after installation, submit signboard installation notification |
| At least 20 days before application | Notify nearby residents in writing | — |
| At time of application | — | Submit prior notice result report |
| Until permit is granted | Continue displaying the plan signboard | — |
Notification is basically carried out in writing, but if neighbors request briefing sessions or individual explanations, you are advised to respond accordingly. The quick reference table shows "briefing sessions" for this reason; it is better to prepare venues and materials in advance assuming you will provide them if requested to avoid disruptions in your application schedule.
The signboard must be displayed continuously from 20 days before the application until permission is received. If proceeding alongside renovation work, choose a location where scaffolding or protective sheeting will not obscure the signboard.
Minpaku Law: Host-Absent Type Has Varied Restrictions Depending on the Area
The Minpaku Law operates under a notification system, with a nationwide annual upper limit of 180 days. In Minato Ward, there are no ward-specific restrictions on host-resident types, which may operate within this 180-day limit.
For host-absent types, operating periods are restricted by ward ordinances in residential-only and educational districts. Check property location zoning with city planning maps and confirm the specific restricted periods with the ward office before submitting notifications. Host-absent types are also required to contract with a housing accommodation management company.
Even in unrestricted areas, the allowed operating period under the Minpaku Law is about half the year. If considering accommodation business investment in Minato Ward, it is advisable to start by checking if the property can obtain ryokan business permission.

Minato Ward ranks highest among the 23 wards in both sales prices for detached houses and rental prices for detached houses. Costs for purchasing detached houses for whole-building minpaku as well as fixed monthly costs when renting and subleasing detached houses start from a higher level than other wards.
On the other hand, gross yields for whole-building income properties are relatively low compared to other wards, indicating thin profits when operated as regular rentals. If targeting revenue exceeding rental income through accommodation business, calculate whether guest rates and occupancy can match the high purchase prices and rent by comparing with surrounding accommodation facility prices.
