I spend an unfortunate amount of time browsing y!ja out of boredom / curiosity, and thought some people might care about some unique/interesting/rare/etc. items that get posted. The higher bid on items are, generally, either pretty normal (e.g. a wii u, ps4), or people selling insanely decked out smartphone game accounts (if you want a Puzzle&Dragons or Monster Strike account for $600USD let me know) but some legitimately cool things pop up often enough. I'll post some new listings whenever if there ends up being any interest.
Some current listings (with actual bids and their price at the time of posting)
Sealed PS1 Nocturne in the Moonlight / Symphony of the Night, ¥80,000
Sega Saturn 太郎丸 / Shinrei Jusatsushi Taromaru, ¥50,000
Neo Geo Power Instinct, ¥70,000
293 Super Famicom carts, ¥51,000
Maybe the most interesting at the moment, a PCB for an unreleased Atlus STG called Wing Force, currently going for quite a high ¥199,000
