SA is a good opportunity for foreigners to experience japanese culture from inside, try go off your limits to communicate with other tenants in Japanese as mmuch as you can, even it is not perfect, you'll make mistakes, but you efforts will be rewarded by the community. SA community is large, you will be able to make various friends, sharing activities inside and ouside the building (games, outdoor activities, restaurant, party, etc). Compare to other sharehouse, here rules a fair and sustainable (ie. no fridge war).
Finding a good place to live in Japan and especially Tokyo may become a challenge for both foreigners and Japanese. So SA is a good choice as a long term property. The range of facilities is wide and even if it is a mix of private and public space, I can easily call it an apartment. That’s also quite affordable too. It is a great place for people who want to be a part of the community. Like to live in a university dorm but for adults. It was really fun and pleasant experience, and I am truly sad it is over.
