I made a return trip to JBS in Shibuya (it's in the Cafe section) and was able to have a long chat with the owner Kobayashi-san. He only opened the place 7 years ago but has been collecting records for over 35 years..amazing to think he had so many albums in a small Japanese apartment. Kobayashi-san is like a lot of jazz cafe and bar owners, very calm and soft-spoken, and seemingly very content in the small world he has created in his cafe. He told me he buys on average one new album every day, is at the cafe every day from 2pm-11pm and has no staff. Whether there are customers or not he'll stay and keep spinning records (while I was there he had on an amazing Harold Land record called "A New Shade of Blue"). A bit of a hermetic life, really far removed from mainstream Japanese society..and quite appealing to all us jazz geeks I think..
