Yahoo Auctions Japan
— What We Actually Offer

Yahoo Auctions Japan (ヤフオク) is one of the largest bidding marketplaces in the world — but Kizuna Proxy doesn't currently place bids on it, or on any auction platform. Here's why, and what we do instead.


Why We Don't Bid on Yahoo Auctions

Auctions close at an unknown final price, and our policy requires payment in full before we purchase anything on your behalf. Those two things don't mix well — a listing can close well above what you budgeted, with no way to walk away once bidding is underway. Rather than take that risk with your money, we've chosen not to offer bidding at all, on Yahoo Auctions or any other auction site.

What We Buy Instead

Most of what people hope to find on Yahoo Auctions is also listed at a fixed, known price on Mercari Japan or Rakuma — Japan's two biggest secondhand marketplaces. A fixed price means you know the total cost before you pay, which fits how we work: you approve a price, then we buy.

What You Can Still Get

If You've Already Found Something on Yahoo Auctions

Send us the link anyway — we'll check whether the same or a similar item is available at a fixed price on Mercari, Rakuma, or in a physical store.

We'll always tell you honestly if we can't find a fixed-price alternative, rather than take on a bid we can't guarantee the outcome of.

A Note on Availability

Whether we're buying online or in person, availability is never guaranteed until we've actually confirmed or purchased the item — secondhand and limited-release items can sell out or get relisted at any time.
