Japan Phone Buyback Prices (iPhone, Android, iPad, Switch — 3 kaitori shops)

Type a model name and get the buyback (kaitori, 買取) prices that three Japanese buyback shops pay for it right now — sealed new, opened and used — in one table with model, capacity, colour, carrier, JAN and the shop's update date. Every row carries a cross-shop key (maker | model | capacity), and a best-price comparison per model is saved with the run.

Resellers and trade-in businesses check these shops one by one to find out where a phone sells for the most, or how much they can pay when sourcing. This Actor does it in one run:

Shop	What it shows	How it is read
買取商店 (Kaitori Shouten, kaitorishouten-co.jp)	新品 (sealed), 新品 開封済 (opened) and 中古 (used) per colour, with JAN, model number, option deductions and the update date	its public product API (one request per 100 listings)
携帯空間 (Keitai Space, keitaispace.co.jp)	未開封品 (sealed) and the top used price; JAN for many gadgets	its search / category pages (12 listings per page)
モバイル一番 (Mobile Ichiban, mobile-ichiban.com)	sealed and opened new prices, used prices, colour and network-restriction deductions, list date	its search form, then one list per model

Unofficial tool. Not affiliated with 株式会社エルシーエス (買取商店), 株式会社オーアール (携帯空間) or 海峡通信株式会社 (モバイル一番). It reads only publicly available price pages, requests only URLs that each site's robots.txt allows, sends one request at a time per shop (2–3 s apart) under a hard request budget, and does not try to get around blocks. It extracts product facts only: no images, no descriptions, no personal data. The prices are the shops' published reference prices; the shops set the final price after inspecting the item. 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

{
  "keywords": ["iPhone 17 Pro"]
}

This reads all three shops for "iPhone 17 Pro" (which also matches "iPhone 17 Pro Max") and stores about 100 rows — every colour and condition the shops list. It needs about 10 requests and finishes in under a minute. モバイル一番 is reached through an Apify residential proxy in Japan by default (it refuses Apify's datacenter IPs); 買取商店 and 携帯空間 need no proxy. The best price per model and condition is in the key-value store record COMPARISON.

Common input mistakes

Wrong	Right	Why
"keywords": ["アイフォン17"]	["iPhone 17"]	The shops write model names in Latin letters.
"keywords": ["iPhone 17"] when you mean only the base model	["iPhone 17"] + "excludeWords": ["Pro", "Air"]	Matching is by whole words: "iPhone 17" also matches "iPhone 17 Pro" (but never "iPhone 17e").
"categories": ["android"]	"keywords": ["Pixel 10", "Galaxy S25"]	Whole-category browsing covers iphone and ipad; everything else is searched by model name.
"shops": ["iosys"]	"shops": ["keitaispace"]	イオシス, じゃんぱら and GEO are not supported (see the FAQ). The run stops right away and lists the valid shops.
"startUrls": ["https://www.mobile-ichiban.com/..."]	"keywords": ["iPhone 16"]	モバイル一番 lists are answers to its search form and have no URL.

Empty results?

• A keyword matches nothing when a shop does not buy the model or writes it differently. Try the shorter model name ("Switch 2" instead of "Nintendo Switch 2 本体") or drop the capacity.
• One shop has rows and another has none: each shop buys a different range of models; that is normal.
• If nothing matches anywhere, the run still succeeds with complete: true and 0 rows, and nothing is charged.

Output

One row per shop, listing and condition (a real row from the verified run):

}

• condition is new or used; sealed is true (unopened), false (opened but unused) or null (the shop does not say). conditionLabel keeps the shop's own wording (新品, 新品 開封済, 未開封品, 新品 simfree未開封, 中古品 ...).
• priceJpy is the buyback price. 携帯空間's used price is an "up to" price (～180,500円).
• priceAdjustments lists what the shop states next to the price: 買取商店 options ({"label": "開封済", "amountJpy": -15000}, 箱なし −1,000), モバイル一番 colour or restriction deductions ({"label": "青、橙", "amountJpy": -3000}, {"label": "△", "amountJpy": -10000} = network restriction △), or a note without amount (amountJpy: null).
• carrier: simfree, docomo, au, softbank, rakuten, ymobile, uqmobile, overseas, wifi or null; carrierLabel is the shop's wording.
• priceUpdatedAt is the date the shop prints (買取商店 per product, モバイル一番 per list); 携帯空間 shows none (null).
• url is the listing's page at the shop (モバイル一番 has no product pages: its top page).

COMPARISON (key-value store record), one entry per matchKey and condition (new, new_opened, used):

{
  "matchKey": "apple|iphone 17 pro|256gb",
  "maker": "Apple", "model": "iPhone 17 Pro", "capacity": "256GB",
  "condition": "used",
  "bestShop": "mobileichiban", "bestShopName": "モバイル一番", "bestPriceJpy": 145000,
  "byShop": { "kaitorishouten": 143000, "keitaispace": 136000, "mobileichiban": 145000 },
  "shops": 3
}

byShop is the highest price each shop shows for that key and condition, across colours and carrier versions — check the rows before you sell (a colour or a carrier version can be priced differently). A run summary per shop and query (requests, rows, stop reasons) is in RUN_SUMMARY.

How matchKey works

Each shop writes the same phone differently (iPhone 17 Pro 256GB シルバー MG854J/A SIMフリー, iPhone 17 Pro 256GB, iPhone 17 Pro 256GB 中古). The Actor removes colour, carrier wording, model numbers and JAN, normalizes spacing (iPhone17 → iPhone 17) and keeps maker, model and storage: apple|iphone 17 pro|256gb. Carrier and colour stay in their own fields. This lines up iPhones, Pixels and other phones named "model + capacity" across the shops. iPads, consoles and accessories are named too differently between shops; use jan or modelNumber for them where the shop provides one.

Input

Every field is optional; {} runs the Quick start.

• keywords — model names, one per line. A row is kept when its listing name contains every word of the keyword as a whole word.
• categories — iphone and/or ipad: every listing of that category at every selected shop (a full daily price list). モバイル一番 reads one list per model (about 40 for iPhone), so allow a few minutes.
• shops — kaitorishouten, keitaispace, mobileichiban (default: all three; Japanese names work).
• startUrls — shop list URLs: 買取商店 /products/list?category_id=17, /category/1/747, /products/detail/27097; 携帯空間 /product/?ca=23 or /product/?kw=....
• makers, conditions (new / used), excludeWords — filters.
• maxItems (500) — rows for the whole run. maxPagesPerShop (5) — list pages per query at 携帯空間 / 買取商店.
• proxyConfiguration — proxy for 買取商店 and 携帯空間; not needed (default: none).
• residentialProxyConfiguration — proxy for モバイル一番 (default: Apify RESIDENTIAL, country JP). It refuses Apify's datacenter IPs, so keep it on; one sticky IP per run, never rotation.

Pricing

Pay per result: each stored row is one result. A run that stores nothing is not charged for results. See the Pricing tab for current prices.

FAQ

Which conditions can I compare? Sealed new (condition: new, sealed: true), opened-but-unused (sealed: false, where 買取商店 and モバイル一番 price it) and used. Used prices assume a good-condition device; the shops lower them after inspection (scratches, battery, network restriction).

Why are イオシス, じゃんぱら and GEO not included? イオシス's and GEO's firewalls refuse this Actor's requests although they are honest (イオシス answers its HTTP client with 403, GEO refuses its User-Agent), and the Actor does not disguise itself. じゃんぱら's disclaimer page requires permission for robot-type automated copying of its pages. Only shops whose robots.txt and terms allow automated reading of their price pages, and that answer the Actor's honest requests, are included. (Flea markets such as Mercari are not buyback shops and are out of scope.)

Why does モバイル一番 make extra requests? Its search shows 20 listings per page and the next pages cannot be opened without a browser. When a search has more pages, the Actor reads the matching model lists from the shop's own menu instead, so nothing is missed. If something is still out of reach, the run says so (complete: false with the reason).

Why a residential proxy for モバイル一番? It drops connections from Apify's datacenter IPs and answers the same honest request from a Japanese residential IP. The Actor therefore sends only that shop's requests through Apify's residential proxy (Japan), keeps one IP for the whole run and never rotates. If the very first request is refused, it is retried once on a new IP and then given up.

What if one shop blocks the run? That shop is marked with a stopReason and is not asked again; the run still succeeds with complete: false as long as other shops returned rows. It fails only when nothing at all was stored and a shop stopped.

Is this data personal? No. The rows are shop prices for products. No seller, customer, staff or contact data is collected, so there is no personal data under the GDPR or Japan's APPI in the output; you remain responsible for how you use it.

How do I credit the source? Every row carries source, sourceUrl and license. Please keep them when you republish, and link back to the shop.
