Hello ^^
Thank you for message.
Now Japanese government is conceding about the law of Minpaku. It's still not enacted at the moment. We can only see what's going to be.
We have never cancelled reservations and had no problems at the moment.
We are under the regulations of Airbnb, so if you need information about those things, it's better to ask Airbnb help desk.
Hope them to be helpful for you.
Best regards,
May
