The initials stand for Jazz Blues Soul, with an emphasis on jazz and coffee during the daytime. The huge, 11,000-disk vinyl collection here also includes an impressive selection of old-school hiphop from the seventies through the nineties. Customers can explore the collection and even make requests, although abrupt changes of genre are discouraged.

Drinks are Y500 each with no cover charge, so it's a comfortable place to just drop in for a quick drink or two, or a cup of coffee in the afternoon. The nighttime crowd seems to vary from all foreigners in the early evening to mostly Japanese towards the end of the night.
