jinboucho antique book heaven.

one of the basics of tokyo is that towns have "topics", the most obvious to many are akihabara where you find electronics everywhere and more recently otaku culture, or shibuya where you will find the young women's shopping paradise. but there are much more distinct smaller towns with likewise more surprising "topics", like ochanomizu for example, which specializes in the sale of musical instrument. and there is jinboucho which has uncountable little used and antique book stores.
