I also did Airbnb in Japan. My host in Tokyo had an entire binder full of maps and travel brochures for us to use, and another binder pointing out nearby places to eat, shop and sightsee. Unlike the other hosts I rented from in  Japan, she and her father lived next door to the rental flat and were very willing to talk to us or even guide us around. The other airbnb places were all clean and well appointed, but having that extra personal touch was very welcome. I stayed with her again before I left Japan.
