If you are planning to visit Japan this summer or later & have been considering Airbnb for accommodation, please note that the law is changing as of June 15th and most of the rentals offered on the website are going to be rendered illegal. The regulations are different in every area, so check with the owner of the listing you are considering to be sure that they know about the changes and that the property either does not violate the new laws OR that they applied for & received the necessary license to operate. For example, in Shibuya, you cannot stay in an Airbnb during the week. You can stay on weekend nights or during school holidays only. This is the kind of thing the owners should be aware of & should be able to help you with. Don't get stuck without a place to stay or risk a run-in with the police!
