Japanese Pokemon Card Sold Comps — Japan TCG Sold Prices

What did this card actually sell for in Japan? Not what a shop is asking — what buyers paid.

One call returns the realized Japanese sale prices for a card, pulled from Yahoo! Auctions and Mercari, resolved down to individual cards (set code + collector number + rarity), and split into raw and PSA/BGS graded copies — because the same card sells for 1.6× to 5× more slabbed, and a third of Japanese listings are slabbed.

pokemontcg.io gives TCGplayer and Cardmarket prices away for free, so Western prices are not a gap. Japanese realized prices are. Nothing public joins a free-text Japanese marketplace title to a typed card identity — that join is this Actor.

What you get

cards[]	One entry per identified card: setCode, cardNumber, rarity, name, and separate raw and graded sold statistics (min / p25 / median / p75 / max / average, each with its own n)
gradedPremium	graded median ÷ raw median per card, with both sample sizes. Measured range on real data: ×1.6 to ×5.03
shopAsk	What a Japanese retailer (Yuyu-tei 遊々亭) asks for the same card today, and the gap to the realized median — only when the row is in stock (see below)
keywordBand	The price band of the whole search term, raw vs graded, over every comparable listing — the denominator
coverage	matchedCount / unmatchedCount / coverageRate, overall and per marketplace
sources	Per-source availability, hit count, sample size and source URL

USD conversion included. No login, no API key, nothing stored between runs.

Three bases, tagged on every single statistic

Every block in the output states all three. Ignoring them is how a price product becomes a lie:

Tag	Values	Why it matters
priceBasis	sold / asking	Yahoo! and Mercari are realized sales; the shop catalog is an asking price
gradingBasis	raw / graded	Never pooled. sv10 114/098 measured raw ¥2,999 vs graded ¥15,100 = ×5.03. 32–49 % of listings are graded, so one blended median describes no card that exists
identityBasis	card / keyword	A keyword band for リザードン spans forty different cards. It is a useful denominator, never a card price

Out-of-stock shop prices are shown but never differenced. An out-of-stock 提示価格 keeps its last value and drifts far above the market — xy08bs 062/059 asked ¥178,000 against a ¥17,750 sold median (×10.03). Publishing that gap would invent an arbitrage that does not exist, so shopAsk.usable goes false and no difference is computed. (In the live run below, three cards hit this — including one asking ¥128,000 with no stock.)

Coverage is published, not hidden

Marketplace titles are free text, so not every listing can be resolved to a card. Measured over 360 real listings:

	Resolved to exactly one card
Yahoo! Auctions	80.4 % of comparable listings
Mercari	48.9 % (shorter titles, usually no collector number)
Combined	62.6 % of comparable listings — 55.3 % of all listings

Identification precision, hand-audited: 99.0 %.

Unresolved listings are not discarded — they fall back to keywordBand with their own n, and coverage.coverageRate always tells you how much of the sample made it. The only listings dropped from every statistic are lots (まとめ / オリパ / N枚 / …) and non-Japanese printings, counted as excludedListings: a 30-card lot at ¥30,000 is not a comp for one card.

Pricing — from $0.02 per call, no subscription

Event	Price	When
card-analyzed	$0.02	Once per card name analyzed
listing-scraped	$0.002	Only if you enable Include individual listings

A default run (one card name) costs $0.02 and takes about 5 seconds. A card name that returns no realized sale price is never charged.

Apify's $5/month free credit covers ~250 default runs. No subscription, no minimum.

Input

Field	Example	Notes
cardNames	["リザードン"]	Japanese. Search broadly — see below. Max 10 per run, $0.02 each
game	"poc"	poc Pokemon (measured default) / ygo / opc / dm / ws / ua / vg / digi / bs / gcg
maxSoldPerSource	100	Sold listings sampled per marketplace (30–300)
minSoldPerCard	1	Hide thin cards from cards[]. Never changes a denominator — coverage and keywordBand are unfiltered
includeIndividualListings	false	Every listing with the card it resolved to and why (+$0.002 each)
convertToUsd	true	Adds USD next to JPY

Search broadly, not narrowly. Use リザードン, not リザードンex. The shop catalog is fetched with the same word, and a narrow word leaves prints like メガリザードンXex out of it — 11 sales were lost that way when measured. Individual cards are separated afterwards, locally, at no extra request cost.

メガリザードンXex is exactly the card a narrow catalog query would have missed.

Who this is for

• Resellers and arbitrage — the Japanese realized price is the number that decides whether an import is worth it, and gradedPremium tells you whether the margin is in the card or in the slab
• Graders — is submitting this card worth the fee? gradedPremium with both n values answers it per card, not per set
• Collectors — what a card really goes for in its home market, not the asking price of the one listing you found
• Card shops and marketplaces — pricing against realized Japanese comps

How it works

Three sources, three separate infrastructures, fetched in parallel; paging inside each stays sequential and throttled to one request per 1.5 s. No browser, no login.

1. Yuyu-tei (遊々亭) — one request returns the whole catalog for the search word (no paging), giving setCode / cardNumber / rarity as typed fields
2. Yahoo! Auctions — closed auctions; an auction counts as sold only with bidCount >= 1, so ended-unsold buy-it-nows never reach a median
3. Mercari — sold-out listings only

Then the join runs locally: collector number first (114/098, 001/SV-P promo numbers canonicalized), then card name plus an explicit rarity. A title with neither is left unresolved rather than guessed. EX (2012) and ex (2023) are treated as different cards — case is the only thing separating ミュウツーEX from ミュウツーex, and conflating them put eleven ¥30,000 sales onto a ¥500 card.

Limits

• Japanese-language catalog. Card names must be in Japanese
• Coverage is 37–80 % per source and varies with how specific the listings are. It is always reported; it is never silently assumed to be 100 %
• Pokemon is the measured default. The collector-number match works for any game, but the Japanese set-name and series tables are Pokemon-tuned, so other games resolve fewer listings — visible in coverage.coverageRate
• Sampled statistics, not a full census: sources[].totalListingsFound is what the marketplace reports, sampledListings is what was actually read
• No image URLs and no description text are collected from the shop catalog (its terms of service forbid reuse of images and copy)
