Catch it the instant
it lists in Japan.

Create a free alert with your search keywords and Japan Alerts watches every new Mercari Japan listing for you, around the clock. The moment something matches, it appears in your live feed — and it's pushed to your Discord, Telegram, email, or phone — instantly on paid plans, as a bundled digest every ~3 hours on the free plan. It's the saved-search notification Mercari Japan doesn't offer.

No — unlike eBay, Mercari Japan has no saved-search email or push notifications, and the same is true of Yahoo! Auctions, Rakuma, and Yahoo! Furima. That gap is exactly why Japan Alerts exists: we monitor all four marketplaces continuously and notify you the moment a new listing matches your search.

Yes. Japan Alerts monitors new Yahoo! Auctions (ヤフオク) listings continuously — including ¥1-start auctions, which we never filter out by minimum price, since a low current bid says nothing about the final price. You'll know about new auctions while they still have days left, not after the bidding war.

Yahoo! Furima — formerly PayPay Flea Market (PayPayフリマ) — is Japan's fixed-price flea-market app, full of listings that never appear on Mercari. Japan Alerts covers it alongside Mercari, Rakuma, and Yahoo! Auctions, and few alert tools watch it at all — so it's where the least-picked-over finds live.

We typically catch a new listing within seconds of it going live in Japan — median well under a minute — and paid alerts are delivered immediately. That speed matters: the best-priced grails on Mercari Japan often sell within minutes. The free plan gets the same finds on a ~3-hour delay — in your feed and as digest alerts.

No. Type your search in English and Japan Alerts automatically matches the Japanese words sellers actually use — porter tanker also matches ポーター タンカー, figure matches フィギュア. You see it as a one-line translation with an on/off toggle; nothing to configure.

Japanese marketplaces generally don't ship internationally, so buyers abroad use a proxy service: it purchases the item with a Japanese address, receives it, and forwards it to you anywhere in the world. Every Japan Alerts notification links to the original listing — paste that URL into Buyee, ZenMarket, FromJapan, Neokyo, or whichever proxy service you prefer, and it handles the rest.

Any of them will get your item home; they differ in fees, consolidation options, and auction support — match the service to how you buy rather than hunting for a universal winner. Japan Alerts doesn't favor or partner with any of them: we hand you the listing first, and you buy through whichever proxy you prefer. Our proxy comparison guide covers the trade-offs honestly.

Yes — that's the core of the product. Connect a Discord webhook (great for reseller servers), link our Telegram bot in two taps, use email digests or custom webhooks — or turn on native push notifications, straight from your browser on desktop and mobile, no extra app needed. Alerts arrive as rich cards with the photo, price, and a direct link to the listing.

Standard alerts match listing titles the instant they're posted. Deep Search (Pro) additionally polls Mercari and Yahoo! Furima's own search engines every few minutes — which index item descriptions — so it also catches bundles and lot listings where your search words only appear in the description. It's how you find the toy camera hiding in a 22-item ¥2,000 lot.

The free plan includes three alerts, plus every find delivered to Discord, Telegram, email, or phone push as a digest every ~3 hours — no card required. Pro (founding price $19/mo) gets you 20 alerts, 5 Deep Searches, and instant delivery — the speed that wins fast-moving listings. Upgrade, downgrade, or cancel in one click from your billing page; no lock-in, no cancellation fees.
