How Long Will Short-Term Rental Income Last? Reading Regulatory Risk from Osaka
Osaka City stopped accepting new applications for its special-zone minpaku scheme on 29 May 2026. According to Kansai Television, applications and enquiries for minpaku licences under the Hotel Business Act surged afterwards — taking a hotel-business licence for a single apartment unit has become, in practice, a way around the closed door. The city now intends to tighten the rules further.
This is not only a question about operating in Osaka. When we buy an income property, we calculate yield on the rules that exist today. What remains when those rules are rewritten during the holding period? This article uses Osaka as a worked example of how to build regulatory change into your numbers.
What actually happened in Osaka?
Special-zone minpaku is the common name for the accommodation business for foreign visitors established under the National Strategic Special Zones Act. Osaka City decided to close new applications, with the Prime Minister's approval dated 28 November 2025, and the cut-off fell on 29 May 2026.
The stated reason was a rise in complaints from neighbouring residents about noise and rubbish disposal. By the end of May 2026, some 8,887 facilities — reported as over 90 percent of the national total — had been approved under the scheme, so it had already reached considerable scale.
Once that door closed, the applications moved next door. Filings and enquiries under the Hotel Business Act rose sharply, and the city responded by proposing to revise the approval conditions themselves.

The statutory guideline figure
There are three schemes, not one. Which will you operate under?
Letting a home on a short-term basis in Japan falls under one of three broad schemes. All three are loosely called minpaku, but they rest on different statutes, carry different approval burdens, and treat operating days differently.
The first decision when assessing an income property is which scheme you intend to use. The scheme determines the equipment you need, the conditions the building must meet, and the levers a local government has to restrict you.
Three schemes for short-term letting (general outline)
| Scheme | Governing law | Operating days | Key characteristics |
|---|---|---|---|
| Special-zone minpaku | National Strategic Special Zones Act, Article 13 | No day cap | Limited to designated special zones; a minimum stay length applies |
| Private lodging business | Private Lodging Business Act | Up to 180 days a year | Notification-based; local ordinances may restrict areas and periods |
| Hotel business (simple lodging, etc.) | Hotel Business Act, Article 3 | No day cap | Licence granted by the prefectural governor; comparatively strict facility and structural requirements |
Principal governing provisions
- National Strategic Special Zones Act, Article 13
- The basis for so-called special-zone minpaku, the accommodation business for foreign visitors. It sets out the eligible zones and approval requirements.
- Private Lodging Business Act, Article 2
- Defines the private lodging business. The number of days on which guests may be accommodated is generally not to exceed 180 per year.
- Private Lodging Business Act, Article 18
- Prefectures and designated cities may, by ordinance, restrict the periods during which the business may operate in specified areas. This is one reason conditions differ by municipality.
- Hotel Business Act, Article 3
- A person intending to operate a hotel business is generally required to obtain a licence from the prefectural governor or equivalent authority.
- Building Standards Act, Article 48
- Restricts permitted building uses by zoning district. Whether a property can be used for lodging at a given location also turns on this provision.
Why did building structure become a condition?
Osaka's draft ordinance revision would, in principle, exclude wooden and steel-frame row houses and apartment buildings, adding reinforced concrete or steel-reinforced concrete construction as a condition of the operating licence.
The justification offered is complaint data. Of the noise complaints the city received in FY2024–2025, more than 80 percent — 243 cases — concerned facilities in wooden or steel-frame buildings. Because complaints clustered in buildings with poorer sound insulation, the city moved to screen on structure at the point of entry. It has also asked the national government to amend the law so it can strengthen guidance and supervision.
How should you stress-test the assumptions?
Generalised, the Osaka sequence runs: close one scheme, watch applicants move to the adjacent scheme, then see that one tightened in turn. From the closure of special-zone applications to the surge in hotel-business filings and the proposed structural requirement took under a year.
The lesson is not that short-term letting should be avoided. It is that regulatory change is one of the inputs to an investment decision. The trouble starts when yield is calculated on the assumption that rules will hold, and that single scenario becomes the whole case.
In practice, running three sets of numbers rather than one makes the decision clearer. First, short-term letting under the current scheme. Second, that scheme becoming unavailable and switching to another. Third, neither being available and the unit let on an ordinary residential lease. If the third case still covers the loan and running costs, the property can absorb a change in the rules.
Common oversights and how to address them
✕Buying on the assumption that today's yield can be sustained indefinitely, then losing the exit when applications close or an ordinance is revised.
→Prepare a second set of numbers before purchase, based on an ordinary residential lease if short-term letting becomes unavailable.
✕Assuming that if one scheme closes you can simply switch to the next, only to find its requirements raised as well.
→Check the alternative scheme's requirements — structure, facilities, zoning — in advance, and assess whether your property would meet them.
✕Reviewing only the administrative licensing requirements and never reading the condominium management by-laws.
→Confirm any short-term letting provisions before purchase, using the important-matters explanation and a copy of the by-laws.
✕Waiting for complaints before deciding how to respond, until continuing to operate becomes difficult.
→Set operating rules for noise and rubbish disposal and a contact procedure before you open, and inform neighbours.
Before choosing a property for short-term letting
- Confirmed the building structure (wooden, steel-frame, reinforced concrete, etc.) from the certificate of registered matters or equivalent
- Decided which scheme the property would operate under: special-zone minpaku, private lodging business, or hotel business
- Checked the current application status of that scheme in the municipality's published materials
- Confirmed the zoning district and whether lodging use is permitted there
- For a condominium, checked the management by-laws for any prohibition on short-term letting
- Modelled the numbers under an ordinary residential lease in case short-term letting becomes unavailable
- Established operating rules and a contact procedure for handling complaints from neighbours
Frequently asked questions
- Q. If new special-zone applications stop, what happens to facilities already operating?
- A. Closing new applications and invalidating existing approvals are generally treated as separate matters. That said, guidance and supervision are being strengthened, so confirm your specific position with the municipality that granted the approval.
- Q. I have already bought a wooden apartment building. Can it no longer be used for short-term letting?
- A. Structural requirements differ by scheme and by municipality. Osaka's draft ordinance points toward excluding wooden and steel-frame row houses and apartments in principle, but that is one city's policy and does not automatically apply elsewhere. Check with the municipality where the property is located.
- Q. How far should regulatory risk be examined when selecting an income property?
- A. At minimum, look at three layers: the scheme available now, the fallback if that scheme closes, and the numbers under an ordinary residential lease if neither is available.
- Q. Given that regulation is tightening, should short-term rental investment be avoided altogether?
- A. The direction of regulation alone does not settle the question. What matters is whether the numbers were built on the assumption that rules can change.
