The problem
Japan has gear you can’t get anywhere else. And you can’t reach it.
✕ Access
Half-price grails and Japan-only models sit on Yahoo Auctions & Mercari — domestic-only, in Japanese. Dealers “can’t ship to foreigners.”
✕ Price
You can’t see what an IEM, headphone or DAP actually goes for in Japan — so you can’t tell a deal from a markup.
✕ Condition & fakes
Worn pads, failing drivers, re-shelled units, counterfeits — described in shorthand you can’t verify from abroad.
What you get
A Japan-market desk in your pocket.
Not another measurements site. Japan-specific intelligence plus an engineer’s eye on build and authenticity — the things that decide whether you win or overpay.
01 / PRICE
Real Japan price
What an IEM, headphone or DAP actually sells for in Japan right now (Yahoo Auctions, Mercari, e-earphone, Fujiya) — so you never overpay.
02 / GRADING
Build & authenticity checks
Drivers, shells, cables, wear — and whether a unit is genuine. Read condition like an engineer before you commit.
03 / JP-ONLY
Japan-exclusive radar
JDM models, region-locked firmware (LDAC/DSEE), domestic-only releases — what’s genuinely worth importing, and what isn’t.
04 / ALERTS
Alerts & sourcing
Deal & restock pings on the models you want, plus which proxies/sellers to use and how customs works.

Who’s building this
An engineer in Japan who buys this gear.
Production/manufacturing engineer based near Tokyo — electronics, acoustics, precision build. I read the Japanese market every day and inspect gear the way I’d check a part on the line. This is the tool I wished existed.
