Yahoo! Auctions Japan (ヤフオク!) Scraper

Scrapes live listings from auctions.yahoo.co.jp, Japan's largest consumer auction marketplace, by keyword, category and/or seller. No login, no API key, no proxy needed.

Built for proxy-bidding services, cross-border resellers, collectors and price-monitoring tools that need Yahoo! Auctions data in a clean, typed form.

What you get

One dataset item per listing:

Field	Example
id, url, title	b1242172828, https://auctions.yahoo.co.jp/jp/auction/b1242172828, 希少 英国限定 200台 MINOLTA AF-C …
currentPrice, buyNowPrice, startPrice (JPY)	16800, null, 14800
bids, bidders, watchers, quantity	7, 4, 21, 1
startTime, endTime (ISO 8601 UTC), timeLeftText	2026-09-02T10:55:39.000Z, 24時間
condition, conditionCode	目立った傷や汚れなし, USED20 (code only on seller-page rows; detail pages give the text)
isFreeShipping, shippingPaidBy, shippingMethods, shippingSchedule, isWorldwideDelivery	true, seller, ["おてがる配送ゆうパケットプラス"], …
categoryId, categoryName, categoryPath, brand	2084005100, コンパクトカメラ, [{id, name}, …], コニカミノルタ
sellerId, sellerName, sellerPrefecture, sellerUrl, sellerGoodRatingPercent, sellerRatingCount, sellerIsStore, isStoreItem	6zME3juXWF7V2s4RXKuFS97aWJmfj, mzo101, 東京都, …, 99.9, 2190, false
description, descriptionHtml, images, imageUrl	full seller description and every full-size image

Fields the site does not provide are null. With fetchDetails: false you get the result-card fields only (title, prices, bids, end time, category ids, seller id and rating, thumbnail; seller pages add condition, watchers, seller name/prefecture/rating count/store flag) at 50 organic listings per request (plus a few promoted cards, flagged isPromoted).

Input

Field	Description
keyword	Search text, as typed on the site (Japanese works best). Optional if categoryId is set.
categoryId	Numeric category id — the number in https://auctions.yahoo.co.jp/category/list/<id>/. Alone it lists the whole category; with keyword it searches within it.
sellerId	Seller id (aucUserId) — the id in https://auctions.yahoo.co.jp/seller/<id> and the sellerId of every scraped item; a full seller URL works too. Lists that seller's live listings; keyword / categoryId narrow within them. Not combinable with listingType other than all. Seller-page rows also carry conditionCode/condition, watchers, sellerName, sellerPrefecture, sellerRatingCount, sellerIsStore without a detail fetch, and the run's SUMMARY record gets a seller profile (id, name, isStore, isEkycVerified, ratingCount, goodRatingPercent).
sort	relevance (site default), endingSoonest, newest, priceAsc, priceDesc, bidsDesc.
listingType	all, auction (bidding only), fixedPrice (定額 / buy-now only).
minPrice / maxPrice	Current-price bounds in yen (whole numbers; the site's own price filter).
maxItems	Stop after this many listings (default 100, max 5000).
fetchDetails	Open every listing page for condition, description, images, seller details (default on).
maxConcurrency, proxyConfiguration	Usual crawler knobs.

Example — film cameras ending soonest, list only:

{ "categoryId": "23640", "sort": "endingSoonest", "listingType": "auction", "maxItems": 500, "fetchDetails": false }

Pricing

Pay per event: one item event per listing saved to the dataset. Nothing is charged for list pages, detail pages that turn out to have ended, or failed requests. The run stops cleanly when your maximum total charge is reached and never charges past it.

Notes and limits

• Seller pages use a different (Next.js) layout than search results; the actor maps both to the same item fields, but seller-page rows have no timeLeftText (use endTime). An unknown seller id fails the run (the site redirects it to its home page).
• Live listings only. Sold-price history (/closedsearch/) is disallowed by the site's robots.txt and is not scraped.
• Terms: the LY Corporation common terms, the Yahoo! Auctions guideline and its detailed rules (checked 2026-09-01) contain no clause against automated reading of public pages; they do prohibit access that puts an excessive load on the servers and masking your IP address through external servers. Keep maxConcurrency at its default (5) or lower and leave proxyConfiguration empty; the site answers plain requests from Apify's own IPs. Do not use the output to contact or profile individual sellers beyond what a purchase requires (the guideline restricts collecting other users' personal information for that purpose).
• The site paginates to roughly 5000 results per query; narrow with categoryId, listingType or minPrice/maxPrice to go deeper into a topic.
• Listings can end between the search page and the detail fetch; those are skipped (not charged) and the crawler keeps walking until maxItems is reached or results run out.
• Prices are in Japanese yen as integers. Times are converted from JST to ISO 8601 UTC.
