Japan Resale Price Comps (Yahoo Auctions sold, Flea Market, BOOKOFF, Hareruya)

Type in product keywords and get two things back: what the items actually sold for in Japan, and what they are listed for right now. Each keyword also gets a price summary with count, min, quartiles, median, max and mean, kept separate for sold and listed prices.

This Actor is a price comps tool for Japanese second-hand markets. You do not need Mercari data. One run queries:

Source	What you get	Status
Yahoo! Auctions (ヤフオク! closed search)	Final sold prices with sale time, bids, condition and category	sold
Yahoo! Flea Market (Yahoo!フリマ, ex-PayPay Flea Market)	Current asking prices from individual sellers	listed (rarely sold)
BOOKOFF online store	Shop prices for used and new games, comics, books, CDs and DVDs	listed
Hareruya (晴れる屋)	Shop prices for Magic: The Gathering singles, with card grade	listed
Suruga-ya (駿河屋), opt-in	Shop prices for figures, games and hobby goods	listed

Resellers, importers, appraisers and pricing teams usually check these sites one by one. This Actor does it in a single run and returns one English-schema dataset.

Unofficial tool. Not affiliated with LY Corporation, BOOKOFF, Hareruya or Suruga-ya. It collects only publicly available listing pages. It requests only URLs that each site's robots.txt allows. Requests to each site are made one at a time and spaced 1.2 to 30 seconds apart, under a hard request budget. It does not try to get around blocks. It extracts item facts only: no seller IDs, names, ratings or locations, no reviews and no personal data. You are responsible for making sure your own use of the data complies with each site's terms and the law.

Quick start: verified input

The input below was run successfully on 2026-10-04. It needed about 10 requests and took about 7 seconds without a proxy.

{
  "keywords": ["Nintendo Switch", "ポケモンカード"],
  "maxItemsPerSource": 20
}

You get up to 20 items per keyword from each source plus one summary record per keyword. The same summaries are saved to the key-value store record OUTPUT.

Common input mistakes

Wrong	Right	Why
"keywords": ["pokemon cards"]	["ポケモンカード"]	These are Japanese sites. English works for brand and model names (Nintendo Switch, Nikon F3). For anything else, use Japanese.
"keywords": ["Switch"]	["Switch 有機EL 本体"], plus "excludeWords": ["ジャンク", "ケース"]	Broad keywords mix consoles, games and accessories, so the median means nothing. Be specific, and use priceMin / excludeWords.
"sources": ["mercari"]	["yahoo-auctions-sold", "yahoo-flea-market"]	Mercari is not supported. The run stops right away and lists the valid sources.
"bookoffCategory": "toys"	"game", "comic", "book", "magazine", "cd", "dvd" or a numeric genre id	BOOKOFF is browsed by category (see the FAQ).

Empty results?

• Hareruya returns 0 for anything that is not a Magic: The Gathering card. That is expected.
• BOOKOFF returns 0 when no title in the chosen category contains every word of your keyword. Change bookoffCategory or shorten the keyword.
• If every source returns 0, the run still succeeds with complete: true and empty summaries. Try a Japanese keyword.

Quartiles use linear interpolation (the same method as Excel PERCENTILE.INC) and are rounded to whole yen. The sold window shows how recent the sold items are. Yahoo lists the latest sales first, so for a popular keyword 20 sold items may cover only the last half hour. Raise maxItemsPerSource and maxPagesPerSource to cover a longer period. The example above uses a deliberately broad keyword, which is why games and consoles are mixed together.

Input

Every field is optional, and {} runs the Quick start. Main fields: keywords (up to 200), sources, maxItemsPerSource (20), maxPagesPerSource (2, one page is one request), soldWithinDays (0 = no cutoff), condition, priceMin / priceMax, excludeWords, bookoffCategory (game). The four default sources need no proxy. Suruga-ya uses its own surugayaProxyConfiguration (RESIDENTIAL, JP).

Pricing

Pay per event: a small run start fee, a fee per result written to the dataset (item and summary records alike), and a fee per keyword summary. A keyword is billed only when at least one priced item backs its summary. See the Pricing tab for current prices.

FAQ

Does it include Mercari? No. This Actor uses only sources whose robots.txt and terms the developer has reviewed. On these sites, Yahoo! Auctions sold prices are the main reference for real transaction prices in Japan.

Why is BOOKOFF limited? BOOKOFF's store has no server-side keyword search. The keyword only re-orders a category. The Actor browses the category you choose and keeps an item only if every word of your keyword appears in its title, author or genre label. Results are relevant, but you will not get every match.

Are Yahoo Flea Market prices sale prices? Mostly not. The publicly allowed search lists items that are on sale, so they are listed prices. For sold prices, use Yahoo! Auctions. Its closed search also includes items sold on the flea market (details.isFleaMarket).

Why is Suruga-ya opt-in? suruga-ya.jp blocks datacenter IPs, and its robots.txt asks for 30 seconds between requests. It needs a Japanese RESIDENTIAL proxy, which is billed by Apify as platform usage. Even then, some proxy exits are refused. If the first request is refused, the Actor retries once on a different exit. If that also fails, it skips Suruga-ya while the other sources continue.

What if one site blocks the run? That source is marked with a stopReason, and the run still succeeds with complete: false as long as other sources returned items. It fails only when nothing at all was collected and a source errored.

Are duplicates removed across sources? Within a source, yes. Across sources, no. A flea-market item that also appears in Yahoo Auctions results can be counted once in each source.
