I recently talked to Joytalk and I got to choose my housing situation. I had the option of an older house with an additional half room and it was 5000 yen less a month or a newer house with newer furniture and other add-ons. This was a quick decision for me, I choose the newer house. Below is a picture of the layout and the main room.
Although it looks small everything in Japan is small. The housing looks really nice. It is a newer building and everything is furnished. I will also get free appliances and internet/basic cable is provided. The kitchen is tiny but I'm not going to be in there that often. I think I will get an extra futon for when people visit, and I'll set up my laptop on the desk I have. My bed is also in a raised position with storage underneath and 2 stairs leading up to it. I won't be throwing many house parties, but no one really does in Japan (no room).
