2F 1-52-1 Jimbocho, Kanda, Chiyoda-Ku
All used records (and a few CDs) here with vocals & swing jazz being the specialty. Lots of old music journals and magazines too, it's a fun place to browse.
Distance from station: 2 minutes
Come out of A4 and walk up Hakusan-Dori (away from the Jimbocho intersection). This map shows you clearly where it is.
