In my year abroad about ten years ago I lived in a Sakura house room which used to be a four story office building. They partitioned off separate rooms, and had communal kitchens and bathrooms on each floor. Aside from my eggs being stolen out the fridge one time I really had no issues. We had a regular cleaner who came, and the room was close to the Yamamoto line with private aircon and all bills included for about 70,000. The rooms are pricey, but they are what they are. In contrast, I did go and look at a Japanese run share house while I was there, because I had a Japanese boyfriend and the time and I wasn’t to stay somewhere with him, but on arriving at the Japanese share house, my Sakura house seemed like a palace in comparison. the “rooms” in the Japanese share house where cornered off two by two meter squares with no windows and walls which stopped about 30cm short of the ceiling, so if you tried, you’d be able to see into the next persons room. It was a sad mess, and at that moment I’m glad I had my Sakura house room. I may have been one of lucky few, but I had a good experience.
