Hey scjp19,
You already have a dorm assignment in Osaka University? How come? We haven't heard anything yet from the school lol.
I think my professor asked the admission office. They haven't called me or sent me a letter yet.
Regarding the public bath, i know there are people who are not used to it. Some public baths have a separate shower room but I guess you just have to get used to their culture since you're going to live in their country.
