It took Airbnb, which says Japan was one of its top ten countries, about a year to gain legal footing in the country. Short-term Apartment rentals to visitors in Japan was notably picked up in the media, with TV specials centered around (often foreign) guests that didn't obey residential rules, that were noisy, excessively messy or otherwise a nuisance to neighbors. The new 180-day limit is actually pretty long: in London, the rules state a limit of 90 days. Airbnb also has other problems that still need addressing.

The challenge for local authorities will be to strike a balance between opening up a new price band for visitors (and their tourist yen) and ensuring everyone who isn't renting is okay with their temporary neighbors. According to the company, there are already 52,000 Airbnb listings in Japan.
