What are you hunting for?

Every page below watches Japan's four biggest marketplaces for one thing collectors chase — with live listing counts and one-click alert setup. Don't see yours? Any search works: create a custom alert.

Marketplaces市場

Mercari Japan

Mercari (メルカリ) is Japan's biggest flea-market app — millions of listings from Japanese sellers, most of which never ship internationally and sell within hours. Japan Alerts watches every new Mercari Japan listing and notifies you the moment your search matches, with a direct link to the listing — ready to paste into whichever proxy service you buy through. Pro's Deep Search even matches Mercari's own search engine — including item descriptions and bundle lots.

Yahoo! Auctions Japan

Yahoo! Auctions (ヤフオク) is where Japan's rarest items surface — from ¥1-start auctions to dead-stock collections. Being early matters twice here: you get time to research, and time to arrange proxy bidding. Japan Alerts notifies you of new auctions the moment they're listed, not when they're about to end.

Rakuma

Rakuma (ラクマ) is Rakuten's flea-market app — smaller than Mercari, which is exactly why it's less picked-over by overseas buyers and resellers. Japan Alerts monitors every new Rakuma listing alongside Mercari and Yahoo!, so a bargain there never slips past you.

Yahoo! Furima (PayPay Flea Market)

Yahoo! Furima — formerly PayPay Flea Market (PayPayフリマ) — is Japan's third-largest flea-market app, and the hardest for overseas buyers to even browse: the app region-blocks users outside Japan. Almost no alert tool covers it. Japan Alerts watches every new Yahoo! Furima listing — and Pro's Deep Search polls its native search too, descriptions included — making it the least-competitive hunting ground of the four marketplaces.

Archive fashion古着

Porter Tanker bags

Yoshida & Co.'s Porter Tanker line — the MA-1-inspired nylon icon — is dramatically cheaper on Japanese secondhand apps than anywhere abroad, and clean examples in the discontinued colors disappear fast. Sellers list under ポータータンカー; we match both spellings automatically.

Yohji Yamamoto

Mainline Yohji Yamamoto pieces surface on Mercari Japan and Rakuma at prices that would empty a Grailed listing in minutes — archive runway included. Titles are usually written ヨウジヤマモト; an English-only search misses most of them.

Issey Miyake & Pleats Please

Pleats Please, Homme Plissé and mainline Issey Miyake move through Japanese flea-market apps constantly — Japan is where the pleats come from, and where they resurface. Watch イッセイミヤケ and プリーツプリーズ without typing a word of Japanese.

Comme des Garçons

From HOMME knits to archive runway pieces, CdG supply on Mercari Japan and Yahoo! Auctions is unmatched anywhere — sellers write コムデギャルソン or just ギャルソン, and the well-priced pieces are gone the same day they list.

Undercover

Jun Takahashi's Undercover — Scab, But Beautiful, and every era since — appears on Japanese marketplaces long before it reaches Western resale sites, at a fraction of the price. アンダーカバー listings are exactly what our Japanese matching exists for.

visvim

FBTs, Virgils, and kimono-dyed runway pieces circulate on Mercari Japan and Yahoo! Auctions in sizes and prices the Western market never sees. Get pinged the moment ビズビム listings match your size.

Kapital

Kapital's boro, century denim and ring coats sell out at retail and resurface on Japanese flea-market apps at domestic prices — usually titled キャピタル. Alerts mean you see the Friday-night listing before the weekend resellers do.

Number (N)ine

Miyashita-era Number (N)ine is pure archive gold, and Japan is where it lives — most pieces list as ナンバーナイン on Yahoo! Auctions and Mercari. New grails surface weekly; the trick is hearing about them within minutes.

Pokémon & TCGトレカ

Japanese Pokémon cards

Japanese Pokémon cards — cleaner print quality, earlier releases, lower prices than English — flood Mercari Japan and Yahoo! Furima daily as collections break up. Sellers write ポケモンカード or ポケカ; we watch both, plus English titles, around the clock.

PSA-graded Pokémon cards

PSA-slabbed Japanese Pokémon cards trade on Mercari Japan and Yahoo! Auctions well under Western market prices — especially vintage and promos. An alert on psa + ポケモン catches every graded card the moment it lists, before it's cross-posted to eBay at a markup.

Sealed Japanese Pokémon (未開封)

Sealed Japanese booster boxes and packs — 未開封, 'unopened' — are the blue-chip end of the hobby, and Japanese sellers routinely list them below international market. The keyword that matters is 未開封, and it's built into this alert.

One Piece Card Game

The One Piece Card Game's hottest leaders and alt-arts sell out instantly at Japanese retail and reappear on the flea-market apps minutes later — as ワンピースカード. Japan is the source market; alerts put you at the front of it.

Yu-Gi-Oh! (Japanese)

OCG cards, Asia promos and early-2000s holos list all day on Mercari Japan under 遊戯王 — a search most non-Japanese buyers literally can't type. Set the alert once and never miss a binder cleanout again.

Anime figuresフィギュア

Nendoroids

Discontinued Nendoroids either cost a fortune on Western sites or ¥2,000 on Mercari Japan — there's rarely an in-between. Japanese sellers list under ねんどろいど; alerts catch the ones your collection is missing the minute they appear.

Scale figures

Sold-out 1/7 and 1/8 scale figures resurface constantly on Yahoo! Furima and Mercari as Japanese collectors rotate shelves — often boxed, often under retail. Watching the scale keywords catches what the general searches miss.

One Piece figures

P.O.P., Ichiban Kuji last-one prizes, and event exclusives — One Piece figure grails list daily as ワンピースフィギュア on the Japanese apps, at prices the export market doubles. Get there first.

Dragon Ball figures

From vintage Super Battle Collection to modern Ichiban Kuji, Dragon Ball figures move through Mercari Japan in volume — ドラゴンボールフィギュア is one of the busiest searches on the platform, and the good ones don't sit.

Gunpla & Gundam kits

P-Bandai exclusives and retired MG/RG kits that resell for triple abroad list daily on the Japanese apps as ガンプラ — often unbuilt in shrink. An alert is how you catch the ones that never reach export shops.

Hatsune Miku figures

Racing Miku, seasonal exclusives, and long-retired scales — 初音ミク figures are a collector economy of their own in Japan, and the domestic listings beat export prices by wide margins.

Film camerasカメラ

Contax T2 & T3

Japan is the world's best market for the Contax T2 and T3 — more bodies, more honest condition notes (ジャンク means junk, and we can filter it), better prices. New listings surface daily on ヤフオク and Mercari; the clean ones sell within hours.

Pentax 67

Bodies, the coveted 105mm f/2.4, and kits with wooden grips — the Pentax 67 system lists on Japanese marketplaces at prices that justify the shipping several times over. Watch ペンタックス 67 without knowing a word of Japanese.

Olympus mju (μ)

The mju-II and its siblings hide under three different spellings on Japanese apps — μ, ミュー, and mju. Our alert matches all of them, which is exactly how you find the ¥8,000 one instead of the $300 eBay one.

Ricoh GR series

Film GR1s and digital GRs alike surface on Mercari Japan daily — リコー GR — with the honest-condition, boxed examples going fast. Japan is Ricoh's home market; the supply difference is dramatic.

Mamiya medium format

Mamiya 7 rangefinders, RB/RZ systems and C-series TLRs — Japanese pro shops and estates feed a steady stream of マミヤ gear onto Yahoo! Auctions that Western dealers buy up and triple. Alerts are how you shop upstream of them.

Film cameras (all)

The broad net: every listing tagged フィルムカメラ across all four marketplaces. Pair it with a price cap and it becomes a dead-stock detector — Japanese households still surface untouched film gear every single day.
