As it states very clearly on my listing in this house we must be careful about noise in this house as it is traditional architecture which is not very sound-proof and usually we have no problems with most of our guests. All Airbnb in houses owned by individuals in Japan who don't have a hotel license is illegal. That means most of the hosts here. Having a homestay operation - charging for offering a homestay experience - is legal and that is how Japanese get by it. There are thousands of homestays all around Japan. I told these guests many times in emails the house was too small for them but they pleaded many times to break our rules. We don't advertise this house for 8 people. Our information is (email hidden)ease read the information carefully before you come.
