Mostly for my own reference, this is a list of less well-known places to hunt down old/rare/unusual stuff in Japan. May be updated occasionally. No idea how well these work with shopping proxies. The obvious ones: Rakuten, Amazon, Mercari, Yahoo Auctions
General stuff:
- Suruga-ya (Don’t miss the electronics category; note that a lot of gun stuff ends up in the 18+ restricted category)
- Sofmap re-colle (mostly electronics)
- Hard-off Net Mall
- Rakuma (kind of useless now)
- Paypay Flea Market (Linked to YAJ but apparently not all listings)
R/C stuff:
- Super Rajikon (also good for gun stuff)
- Rakusei Model
Audio stuff:
- e-earphone
- Fujiya Avic (they used to have an audio gear rental service, it might come back)
- Soundhouse (particularly pro-oriented studio stuff)
Gun stuff:
- airgun.jp (Don’t confuse the for-sale lists with the trade-in price list)
- d-stage gunnet
- Echigoya
Bike stuff:
- Buychari
- Crown Gears (Not cheap, same company as Map Camera)
- Uemura Cycle Parts Parts (their real stores are more fun than online)
Others:
- Watch Shop L (found walking around the area)
