Masuda-san sadly passed away in 2012.
Stardust is an old bar, first opened in Asagaya in 1971 by the very chatty Masuda Junko-san. It's been at its current spot for about fifteen years and has a steady customer base of mostly locals. It's a dark basement bar with beautiful photos of jazz greats all around the place (as well as randomly hung American flag). The kind of bar that would have been plentiful back in the 60s and 70s but now is becoming all too rare.
Masuda-san plays all genres of jazz and is happy to take requests. Just be ready to wait awhile for your drinks while she chats away happily to you in Japanese (whether you can speak it or not!) Lovely lady and a lovely bar.
