I've got mixed feelings returning from Japan. My best and worst stays were both AirBnB's. The best, which is still listed, came from a host who owned the place and very thoughtfully went out of her way to share local things to do. The worst was run by a nebulous "company" that gave us half the rooms promised, at an apartment where residents/management had put up "Foreigners cause crimes, please call the police immediately." signs. It turns out that company had double-booked units in that building using another platform and brazenly gave us another spare unit. This kind of gold rush to capitalize on Japan's tourism boom may indeed need some thoughtful regulation.
