Short term rental rules in Japan
The minpaku notification route caps a private home at 180 nights a year nationally, and many wards cut that further by season or by zone. A ryokan or hotel licence lifts the cap but is a different asset. Underwriting a full year on the notification route overstates revenue by roughly half.
What this does to the numbers
A 180 night ceiling is not a risk note on the side of a deal. It is a cap on the revenue model itself. Underwriting a full year here overstates gross by roughly 51 percent before a single other assumption is tested, which is more than enough to turn a confident buy into a loss.
The building can rule the deal out on its own, whatever the city allows. Verify the by laws, the juristic person or the owners association before you sign anything, because that document outranks your underwriting.

This page is the regime. A verdict is the deal. Run an address and the engine prices it in JPY, against sources that actually cover Japan, with this regime surfaced next to the number.
This is a summary of the shape of the regime, so an operator knows what to verify. It is not legal advice. Councils, prefectures and building by laws override the national picture constantly, which is exactly why we show these rules rather than silently applying them. Confirm with a local lawyer before you commit.
