Japan is where the good used guitars are: 80s and 90s Fender Japan (JV / E / A serials), Made in Japan Tokai, Greco, ESP, Navigator and Momose, Yamaha and Yanagisawa saxophones, at prices well below Reverb and eBay. The listings are only in Japanese, each shop words things differently, and "Made in Japan" is buried in a brand label or a staff comment. This Actor turns Japanese shops (and the dozens of shops on J-Guitar) into one clean, English dataset you can pipe into Google Sheets, n8n, Slack, Discord or your own pricing model.

Who uses it

You are…	You use…
A Reverb or eBay seller sourcing from Japan	search with a grade floor and a max price; reverbCondition is ready to paste; monitor to be first on new stock
A Made in Japan collector (Fender Japan, Tokai, Greco, Burny, ESP…)	search / monitor on a brand or model code; filter on madeIn: "Japan", era: "1980s", accessories.caseType: "hard"
A vintage Fender Japan hunter	monitor on "Fender Japan" or a code ("ST57", "TL52", "JB62") with alerts to Discord; history for how the Japanese median moves
A dealer benchmarking Japanese prices	stats (median per model, by shop and grade) and history

Shops

Shop	Id	Listings	What you get
Shimokura Gakki (下倉楽器: Ochanomizu, Omiya, Hachioji and the "Second Hands" used-guitar shops)	shimokura	~1,400 used instruments: electric / acoustic / classical guitars, basses, ukuleles, woodwinds, brass, effects	no shop grade (conditionGrade is null; the shop writes a free-text condition note instead). Brand as the shop labels it ("Fender Japan", "FENDER USA"), model, production year from the title ("2010～2012年製"), branch, price. From the product page: case ("original hard case") and year
J-Guitar (Jギター: a marketplace listing shops across Japan: Kurosawa, Gakkido, Woodman, Yamano, Miki Acoustic INN, Shimokura and more)	jguitar	~11,000 used instruments on sale (guitars, basses, amps, effects…)	one condition scale for all shops (5[M] … 1[P]), brand, model, year, price, and the listing shop in shop: one J-Guitar search covers dozens of shops at once. From the product page: brand label, model code, category, case
Ishibashi Music (イシバシ楽器, 12 stores: Ochanomizu, Shinjuku, Shibuya, Yokohama, Umeda, Fukuoka…)	ishibashi	~8,500 used instruments (guitars, effects, basses, amps, drums, wind instruments, keyboards…)	brand / model, its 7-step rank (S / A+ / A / B+ / B / C+ / C, read per rank list), price, store. From the product page: category, case
Shimamura Music (島村楽器, stores nationwide, mostly in shopping malls)	shimamura	~5,500 used instruments (guitars, basses, keyboards, wind instruments, drums…)	no shop grade (conditionGrade is null), brand, model, production year from the title, price, store, stock (sold cards stay listed as 在庫切れ). From the product page: category, case
Ikebe Music (イケベ楽器, Shibuya / Akihabara / Osaka specialist stores)	ikebe	~1,400 used and vintage instruments	no shop grade (conditionGrade is null), maker, model, price, category. From the product page: store, case
Hard Off Off Mall (ハードオフ オフモール, stores nationwide)	offmall	~13,000 on sale: electric and acoustic guitars, basses, woodwinds, brass	brand, model code, grade N / S / A / B / C / D / ジャンク, price. From the product page: case, store, and year / "Crafted in Japan" from the staff comment

Shimokura lists part of its stock on J-Guitar too, so a few instruments can appear twice (shimokura and jguitar with shop: "下倉楽器 …").

Shops not included

What you can do

Mode	What it does
search	Listings matching keywords / brands / grades / price. Keywords match brand + title in English or Japanese, and model codes. For each listing in the result, the product page is read once to add case, store, year and country when the listing itself doesn't say.
stats	Per-model summary of in-stock listings: count, min / median / max in JPY and USD, broken down by shop and grade, plus the cheapest listing. Models are grouped by brand + model code, so the same guitar groups across shops.
monitor	Run on a schedule. It keeps a snapshot and emits only what changed: NEW, PRICE_DROP, PRICE_UP, SOLD_OUT. An optional webhook goes to Slack / Discord / n8n / Make / Zapier.
history	Daily min / median / count per model, by shop and grade, from stored daily snapshots. There is no crawling, so it returns in seconds. Needs keywords, brands or models.
deals	In-stock listings at least dealThresholdPct % (default 15) under the median of the same model in the same grade or better, best dealScore first. Statistics only. See Deals.

Made in Japan (madeIn) and the Fender split

madeIn is the country of manufacture: Japan, USA, Mexico, Korea, Indonesia, China, France, Germany, or null when nothing says. madeInSource tells you where it came from, in this order of trust:

1. title: the listing says it ("Made in Japan", "日本製", "Crafted in Japan", "MIJ"), or names a one-country model line ("American Standard", "American Vintage" → USA).
2. brand: the shop's brand label carries the country ("FENDER JAPAN", "FENDER MEXICO"), or the brand builds in one country only (Gibson → USA; ESP, Momose, Navigator, Yanagisawa, Muramatsu → Japan). Brands that also build abroad (Tokai, Yamaha, Ibanez, Epiphone, Squier…) are not assumed.
3. product-page: the staff comment says it ("CRAFTED IN JAPAN Rシリアル").

Phrases about parts ("USA製ピックアップ", "USA pickups") are ignored, and so is the "US" at the end of Fender Japan codes like "ST57-58US".

Fender is named by country, because that is how buyers search and price it: Fender Japan, Fender USA, Fender Mexico, or plain Fender when the country is not stated. Fender Japan covers both the 1982–2015 Fender Japan era and today's "Fender Made in Japan" line: use year / era to tell them apart. A model line beats a sloppy label: a listing labelled "Fender Japan" but titled "American Performer Stratocaster" is Fender USA. The shop's own label is kept in brandRaw.

Production year and era (year, yearFrom, yearTo, era)

From the shop's wording: "2013年製" → year: 2013, era: "2010s"; "2010～2012年製" → yearFrom: 2010, yearTo: 2012; "80年代製" or "1980s" → era: "1980s"; a lone year at the end of a title ("ST72-75 NAT 1993") → 1993. For listings that don't say, the product page is checked ("シリアルから2004~2006年製であると思われます" → 2004–2006).

Style names are not dates. "Traditional 60s", "'50s", "60年代仕様", "1957年モデル" and "American Vintage II 1957" describe the spec of the guitar, not when it was made, and are ignored. Off Mall's "発売日" (the model's release year) is not used either.

Case (accessories)

"accessories": { "caseType": "hard", "originalCase": true, "summary": "original hard case", "raw": "オリジナルハードケース" }

caseType is hard, semi-hard, soft (gig bag), none, or null when a case is mentioned without its type. It is read from the shop's own accessories field on the product page (Shimokura "付属品", Off Mall "付属品"). That field lists everything included, so a field without a case means none. Without a product page (stats, history), it comes from the title only when the title names a case, otherwise null.

Condition grades, normalized to Reverb's scale

BRAND_NEW > MINT > EXCELLENT > VERY_GOOD > GOOD > FAIR > POOR > NON_FUNCTIONING. reverbCondition holds Reverb's display name ("Very Good"), and the shop's own label is always kept in conditionGradeRaw.

Shop	Raw → normalized
Off Mall	N 新品・未開封 → BRAND_NEW · S 新品同様・廃盤 → MINT · A 使用回数の少ない美品 → EXCELLENT · B 日常使用・傷汚少 → VERY_GOOD · C 使用感・傷汚れ多 → GOOD · D ダメージ多 → FAIR · ジャンク (sold as is, no warranty) → NON_FUNCTIONING
J-Guitar	5[M] 新品同様 → MINT · 4+[NM] ほぼ新品同様 / 4[EX+] 年代から見て状態が良い → EXCELLENT · 3+[EX] 年代相応 / 3[EX-] ほぼ標準的 → VERY_GOOD · 2+[VG+] / 2[VG] 演奏上の問題なし → GOOD · 1+[G] 少し難あり → FAIR · 1[P] 修理が必要 → POOR
Ishibashi	S 新品 → BRAND_NEW · A＋ 新品同様 → MINT · A 美品 → EXCELLENT · B＋ 多少傷あり・使用に問題なし → VERY_GOOD · B 傷・使用感あり・使用に問題なし → GOOD · C＋ 修理が必要 → POOR · C ジャンク → NON_FUNCTIONING
Shimokura, Shimamura, Ikebe	not graded: conditionGrade is null; the product page has a free-text note instead

Filtering by grades therefore drops all Shimokura, Shimamura and Ikebe listings.

Deals

deals mode reads the same listings as stats, then compares each in-stock listing with the other listings of the same model (same model key) in the same grade or better, and returns only those at least dealThresholdPct % under that median:

{ "mode": "deals", "keywords": ["Fender Japan"], "dealThresholdPct": 15, "maxItems": 0 }

Each deal is a normal listing plus:

Field	Meaning
medianJpy (medianUsd)	median price of the listings it was compared with
comparisonCount	how many listings that median is based on
discountPct	how far under the median, in %
dealScore	0–100: the discount (40 % off = full marks) weighted by comparisonCount (1 → 60 %, 5 or more → 100 %). Capped at 50 when comparisonCount is 2 or less (low confidence)

• Models with nothing to compare against are not returned. Grades sold as is (NON_FUNCTIONING) are neither returned nor used as comparisons. Shimokura prints no grade, so its listings are compared with every other listing of the model; an ungraded listing is never used to judge a graded one.
• The market is the listings this run read: use maxItems: 0 (whole shops) or a keyword that covers the whole model, so every listing of "fender japan st57-70tx" is compared.
• No LLM is involved; it is the same arithmetic as stats.

Deal alerts. In monitor mode, "dealsOnly": true outputs and sends only the NEW / PRICE_DROP events that are deals against the listings that monitor tracks, with the same four fields. They are charged as normal monitor events.

Daily deal digest. In deals mode, set alertWebhookUrl (Slack, Discord or any URL) and the best dealsWebhookTop deals (default 10, highest dealScore first, ties broken by the deeper discount) are POSTed once per run, one line each: score, discount, grade, title, price vs median, link. Schedule it every morning (e.g. 0 7 * * *, maxItems: 0) for a short list of the day's best-priced listings; the dataset still holds every deal.

English summaries (optional, your own LLM key). "summarize": true with llmApiKey (stored encrypted) adds summaryEn to every listing in search and deals mode, e.g. "Fender Japan ST57-70TX, 1990s, Very Good, soft case, 22% under Japan median". llmProvider is anthropic (default, Claude Haiku claude-haiku-5-5) or openai (gpt-5-mini); llmModel overrides the model. Listings are sent 25 per request, so the cost grows with the number of listings: with Claude Haiku, 100 listings ≈ $0.003, well under $0.01. Your provider bills your key; the Actor charges nothing extra. Without a key the option is skipped with a warning, and an LLM error never fails the run (the listings are returned without summaryEn).

Input

{
  "mode": "search",
  "sources": ["shimokura", "jguitar", "offmall"],
  "keywords": ["Fender Japan", "Tokai"],
  "grades": ["MINT", "EXCELLENT", "VERY_GOOD"],
  "maxPriceJpy": 150000,
  "maxItems": 30
}

Monitor example (schedule it hourly):

{
  "mode": "monitor",
  "sources": ["shimokura", "jguitar", "offmall"],
  "keywords": ["Fender Japan", "ST57", "JB62"],
  "alertWebhookUrl": "https://discord.com/api/webhooks/XXX/YYY",
  "alertEvents": ["NEW", "PRICE_DROP"]
}

The first monitor run only builds the snapshot and emits nothing. Each monitor keeps one snapshot per shop, keyed by its filters. Give each schedule a distinct monitorId if several use the same filters.

Request budget:

• Every request is one listing page (Shimokura 40 instruments, J-Guitar 50, Ishibashi 72, Shimamura 80, Ikebe 80, Off Mall 30), read newest-first. Shimokura has 8 category lists, J-Guitar 1, Ishibashi 7 (one per rank), Shimamura 1, Ikebe 2 (used, vintage), Off Mall 5.
• An hourly light monitor is normally 24 requests, plus one product page per new listing.
• "fullScan": true reads everything: Shimokura ≈ 40 pages (~2 min), J-Guitar ≈ 224 pages (~30 min), Ishibashi ≈ 121 pages (~4 min), Shimamura ≈ 69 pages (~7 min), Ikebe ≈ 19 pages (~1 min), Off Mall ≈ 440 pages (~8 min). A good setup is a frequent light monitor plus a daily full scan of Shimokura, Ishibashi, Shimamura and Ikebe.

Price history since 2026-11-05

The Actor's own scheduled full scans store the complete inventory of each shop: Shimokura, Ishibashi, Shimamura and Ikebe every day (the last three from 2026-11-05), J-Guitar and Off Mall once a week, on Sundays. history mode reads those snapshots:

{ "mode": "history", "models": ["fender japan st57-70tx", "fender japan jb62-58"], "days": 90 }

Each row is one model × day: count, minJpy, medianJpy, maxJpy, plus byShop, byGrade and byShopGrade.

• History is still being collected. Treat the first 30 days as indicative only.
• Off Mall numbers appear on Sunday rows only, so compare them week to week.

Integrations

• Google Sheets: Apify → Integrations → Google Sheets.
• Slack / Discord: paste an incoming-webhook URL into alertWebhookUrl.
• n8n / Make / Zapier: the Apify node, or point alertWebhookUrl at a webhook trigger.
• AI agents: see the next section.

AI agents (MCP)

A dedicated MCP server, @keiya-dev/japan-used-market-mcp (open source, MIT), gives Claude, Cursor and other MCP clients tools backed by this Actor. Pass "market": "instrument" (the server also covers used cameras, its default, and watches):

Tool	Mode
search_listings	search, with Made-in, year / era, case and Reverb condition
price_stats	stats
price_history	history
start_monitor	creates a scheduled monitor (Task + Schedule) in your Apify account
list_markets	shops and grades per market (no run)

Claude Desktop: add this to claude_desktop_config.json. On macOS it is ~/Library/Application Support/Claude/claude_desktop_config.json; on Windows, %APPDATA%\Claude\claude_desktop_config.json. Then restart the app:

{
  "mcpServers": {
    "japan-used-market": {
      "command": "npx",
      "args": ["-y", "@keiya-dev/japan-used-market-mcp"],
      "env": { "APIFY_TOKEN": "apify_api_..." }
    }
  }
}

Get the token at Apify Console → Settings → API & Integrations. Runs are billed to your Apify account, as with any other run.

Then just ask: "Find a Made in Japan Fender Jazz Bass from the 80s with a hard case under $1,000", "What's the median price of a Fender Japan ST57-70TX in Japan?", "Alert me on Discord when a new Tokai Love Rock appears."

Claude Code: claude mcp add japan-used-market -e APIFY_TOKEN=apify_api_... -- npx -y @keiya-dev/japan-used-market-mcp

Remote / HTTP clients: run npx -y @keiya-dev/japan-used-market-mcp --http --port 3000. The endpoint is /mcp (Streamable HTTP); send your token as Authorization: Bearer <APIFY_TOKEN>.

The generic Apify MCP server also works: add the Actor keiya_dev/japan-used-instrument-market as a tool.

Limitations & fair use

• We read only public listing pages at low request rates and return factual listing data: brand, model / code, price, condition grade, stock, shop and URL. Product photos and the shops' own description text are not copied into the output.
• Prices are the shops' tax-included asking prices (税込), not sold prices. USD is a mid-market conversion for convenience. Shipping is not included.
• madeIn, year and case come from the shops' own words. When a shop doesn't say, the field is null: nothing is guessed from serial numbers.
• Only public listing pages and the product pages of returned or alerted listings are read. There is no login, no search endpoint and no sort parameter that robots.txt forbids.
• Shimokura, J-Guitar (販売中 filter), Ishibashi, Ikebe and Off Mall list instruments on sale only; Shimamura keeps sold cards at the end of its list as 在庫切れ (inStock: false). A sold instrument disappears, and SOLD_OUT for it is detected on full scans.
• If a shop's bot protection challenges a run, a page can't be loaded or a shop changes its layout, the run fails with a message saying what to do. It writes no partial data, charges nothing and leaves the monitor snapshot unchanged. A category the shop itself reports as empty today is skipped, not treated as an error.
• Not affiliated with any of the shops.

Changelog

• 2026-11-05 — keywords: words are AND'ed. A keyword with several words now matches listings that contain all of its words, in any order and position ("Fender Japan Jazzmaster" no longer needs the words side by side). Keywords are still OR'ed with each other. Compatibility: single-word keywords and phrases that appeared side by side still match, but a multi-word keyword can now match more listings than before (e.g. Leica M → "leica" + "m", and "m" is in "mm"). To keep the old exact-phrase behaviour, wrap the keyword in double quotes: "\"Leica M\"" in JSON, "Leica M" in the Console. Monitors whose keywords change get a fresh baseline unless they set a monitorId.
• 0.3 (2026-11-05): J-Guitar (~11,000 used instruments from many shops, its 9-step condition scale mapped to Reverb's, the listing shop in shop), Ishibashi Music (~8,500 used instruments from its 12 stores, 7-step rank), Shimamura Music (~5,500 used instruments, not graded) and Ikebe Music (~1,400 used and vintage instruments, not graded) as new sources.
• 0.2 (2026-11-05): deals mode (listings under the same-model, same-or-better-grade median, with dealScore), dealsOnly for monitor alerts, optional English summaryEn with your own Anthropic / OpenAI key. Output is factual listing data only: imageUrl and the shops' free-text notes are no longer returned.
• 0.1 (2026-11-04): Shimokura Gakki (all used instruments, no shop grade) and Hard Off Off Mall (guitars, basses, woodwinds, brass). Search / stats / monitor / history, Fender split by country, madeIn, year / era, case, Reverb-scale grades.
