Today I happened to find a wonderful blog called Surviving in Japan.
It is full of useful infos for all the foreign residents, especially those who are new to Japan, such as "how to transfer money to/from Japan," "how to do a bank transfer," "How to find cheese in Japan," etc.
American girl named Ashley, who had lived in Japan for several years, has this blog for sharing what she learned through her own experience. This is the best how-to guides for living in Japan I have ever seen. As a foreigner she knows what foreigners need to know, much better than Japanese.
Seems like she has already gone back to her home country, but she keeps posting back in the U.S.
It is definitely worth checking.
