Yahoo! Auctions Japan for synths: the third door, after the Hard Off junk corner and Digimart shop stock

[RenSynthJp]

Closing out the set. Thread one was Hard Off, where untested gear washes up in a corner of a second-hand chain. Thread two was Digimart, where the actual instrument shops list their graded, tested stock online. Both threads had the same hole in them, and a couple of you poked at it: what about the stuff private owners sell directly? In Japan that is Yahoo! JAPAN Auctions (ヤフオク!), and it is a genuinely different market with different rules.

Some notes from working it. No affiliation with Yahoo, obviously.

What is actually on there

Yahoo Auctions is where Japanese households and small dealers clear out. For us that means: 80s and 90s Japanese-market Roland, Korg, Yamaha and Kawai gear, the JX/MKS/M1R/TX rack generation, Boss and Maxon pedals in bulk lots, and a steady stream of "cleaning out my late father's music room" listings that never get near an English-language site. Prices sit under Digimart's, because you are buying from someone who wants the room back, not from a shop that has to warranty it.

The trade-off is the obvious one: no shop warranty, descriptions written by amateurs, and ノークレーム・ノーリターン (no complaints, no returns) on a lot of listings. Same vocabulary as the Hard Off thread applies — 動作確認済 tested, 完動品 fully working, 通電のみ確認 powers on only, ジャンク as-is, 訳あり known fault. If a listing has none of those words and only photos, assume untested.

Why you cannot just bid

A Yahoo! JAPAN ID normally wants a Japanese phone number, a Japanese address and a Japanese payment method, and sellers ship domestically only. yahoo.co.jp is a separate company from the Yahoo you know in the States. So overseas bidders go through a proxy that holds a Japanese account, bids on your instruction, pays the seller in yen, receives the item at a warehouse in Japan and forwards it on.

What the middle step costs, roughly

Worth knowing before you fall in love with a listing:

- Auction proxy fee: expect a few percent of the winning bid. The service I use charges (winning bid + tax) x 3%, minimum 200 yen, maximum 300 yen per order, so on anything above about 10,000 yen it is effectively a flat 300 yen. That is the smallest number in this whole exercise.
- Payment is two-stage: item plus service fee first, international shipping later, once the thing is physically in the warehouse and weighed. Nobody can quote you the real shipping number before that.
- Domestic shipping inside Japan, seller to warehouse, is on you. Budget 1,000-2,000 yen for a pedal-sized box, more for anything with a keybed.
- Consolidation is where the money is. Multiple wins into one outbound box beats shipping each one home, by a lot.
- US buyers: the 800 dollar de minimis exemption was revoked on 2025-08-29, so small parcels into the States are dutiable now. Price that in.

The practical bit

Auctions run to a clock and most action happens in the last minute, so bidding through a human middleman by email does not work. Whatever service you use, check it can place a timed bid for you rather than asking you to wake up at 3am Japan time.

And for a sanity check on what synth gear is currently listed in Japan and what it goes for, this is the search I keep open: synthesizers listed in Japan right now. Same disclosure as the last two threads: that second link is the proxy service I use, so read it as a price reference rather than a recommendation.

Open question for the board, because I have never got a straight answer: has anyone shipped a fully weighted 88 out of Japan and had it arrive intact? Every quote I get makes it look insane next to just buying the same board locally, and I want to know whether anyone has actually made that maths work.
