Tokyopop
Tokyo is a music shopper's paradise. It's packed with niche music shops. It's hard to keep track of them; I noticed that some came and went over time. Also, it's very difficult to find them without someone to show you the way. I made this page in hopes it might guide someone to the right areas. Even when I lived there, it took me months to be able to find my way instinctively and directly to these areas.

Shinjuku (Vinyl Japan, Das Gemeine, Loft, etc.)
Shibuya (Zest, DMS, etc.)
Shimokitazawa (Highline)
Nakano, etc. (Fujiya Avic)
