Japan Real Estate Brokers Register (MLIT 宅建業者)

Licensed real-estate brokers in Japan (宅地建物取引業者), straight from the Ministry of Land, Infrastructure, Transport and Tourism's official register — by prefecture or company name, with license number, validity dates, head-office city, guarantee and trade associations, office count and staff counts.

This Actor searches MLIT's public company-information system (建設業者・宅建業者等企業情報検索システム, etsuran2.mlit.go.jp) — the register behind every licensed real-estate brokerage in Japan — and returns corporate license holders as clean JSON with an English schema. Japanese values (company names, associations) are kept as published, so they match what you see on property ads and company websites.

Unofficial tool. Not affiliated with or endorsed by MLIT or the Government of Japan. Records are edited/processed data from the register, published under 公共データ利用規約（第1.0版）(PDL 1.0), which permits commercial reuse with attribution. Every record carries the required notice: 出典：国土交通省 建設業者・宅建業者等企業情報検索システム（https://etsuran2.mlit.go.jp/TAKKEN/）の宅地建物取引業者情報を編集・加工して作成.

Quick start — verified input

Copy-paste this into the input (JSON tab) or send it via the API. It was run successfully on 2026-10-13: 20 licensed brokers headquartered in Tokyo, each with its company page and office count, in about one minute.

{
  "prefecture": "Tokyo",
  "maxItems": 20
}

Running with an empty input {} does exactly the same.

Common input mistakes

Wrong	Right	Why
"prefecture": "東京都" or "13" (via API)	"prefecture": "Tokyo"	The platform checks the dropdown values (47 English names, or empty) before the run starts.
"prefecture": "Yokohama"	"prefecture": "Kanagawa"	Cities are not prefectures.
"companyName": "株式会社三井不動産"	"companyName": "三井不動産"	The register searches the name without 株式会社 / 有限会社 (a leading or trailing one is removed for you).
"companyName": "三"	"companyName": "三井"	At least 2 characters.
"prefecture": "" with nothing else	add "companyName" or "licenseType": "minister"	Unfiltered national lists are not supported; the run would fall back to Tokyo.
"maxItems": 5000	"maxItems": 1000 and split by companyName / licenseType	One run returns at most 1,000 brokers.

Invalid values stop the run immediately — before any request to the register — with a message that names the field and lists the valid values.

Empty results?

A run that ends with 0 records and complete: true is not an error. Typical causes:

• the register has no broker whose name contains your companyName fragment in that prefecture (try a shorter fragment, the katakana reading such as "ミツイ", or "officeScope": "anyOffice" to include branch offices);
• every match is an individual (sole-proprietor) broker — those are always excluded (see FAQ);
• includeDetails: false (list mode) and none of the names carries a corporate designator such as 株式会社.

A run with no records incurs no per-record charges.

Who is this for?

• Proptech and real-estate SaaS sales — build target lists of licensed brokerages by prefecture, filter by size (staff, licensed agents, offices) and by association membership (e.g. 全宅連 / 全日 members, the ハトマーク and ウサギマーク networks).
• Market research — count and profile licensed brokers in a region; license renewal counts (the number in parentheses) show how long a firm has been licensed.
• Counterparty and ad verification (KYB) — confirm that a company's license number, licensing authority and validity period match the official register before you sign or publish.

Input reference

Field	Default	Meaning
prefecture	"Tokyo"	One of the 47 prefectures (English name). Empty = all of Japan, only together with companyName or licenseType: "minister".
companyName	—	Fragment of the trade name. Kanji/kana as written searches the name; katakana only searches the registered reading. Latin letters are converted to the register's fullwidth form.
licenseType	"any"	minister, governor or any.
officeScope	"headOffice"	headOffice = head office in the prefecture; anyOffice = any office there, including branches of nationwide firms (each company once).
includeDetails	true	Read each company page (validity, associations, counts, and the authoritative corporate/individual flag). false = fast list mode, 50 brokers per request, corporate-designator names only.
includeOfficeCount	true	Read each office list to return officeCount (one more request per broker).
maxItems	20	1–1,000 brokers per run. About 3 seconds per broker with details and office counts.
maxApiRequests	0 (automatic)	Hard request budget, at most 2,500. When it runs out the run still succeeds with what it collected and complete: false.
proxyConfiguration	no proxy	Not needed: the register answers direct requests.

A run summary (RUN_SUMMARY in the key-value store) reports the register's total, rows scanned, individuals excluded, requests used, and whether the result is complete.

FAQ

Where does the data come from, and how fresh is it? Live from MLIT's official register, which the ministry updates about twice a month for real-estate brokers. The register shows what the licensing authorities (MLIT regional bureaus and prefectures) have recorded; occasionally a validity period is shown as expired while a renewal is being processed.

Are individual (sole-proprietor) brokers included? No — corporations only. The register records whether each licensee is a corporation or an individual (法人・個人の別), and the Actor excludes individuals using that flag. In list mode, where the flag is not read, only names with an explicit corporate designator are returned. The run summary shows how many were excluded.

Why are there no representative names, phone numbers or e-mail addresses? By design. Representative names, the names of branch managers and licensed agents, and phone numbers are never read or stored — the parser locates those columns only to skip them. The register does not publish e-mail addresses or websites. Office lists are only counted. Addresses stop at the city/ward level.

Can I download the whole country? No. Searches are always scoped (prefecture, company name or license type), one run returns at most 1,000 brokers, and every run has a hard request budget. Split larger lists over several runs.

What about server load? Requests are strictly one at a time, at least 1.5 seconds apart, with exponential backoff, Retry-After support and no block evasion. If the register refuses or changes its layout, the run stops with a clear message — as a partial success if records were already collected, as a failed run otherwise.

Legal and privacy notes This Actor collects only data the register publishes openly under PDL 1.0. You are responsible for complying with the source's terms and with the laws that apply to your use (for example Japan's Act on the Protection of Personal Information or the GDPR) — in particular when you combine these records with other data. Keep the attribution notice when you publish or redistribute the data, and do not present it as an official MLIT publication.
