Automate the Registry Information Service with a workflow

A workflow runs your methods as one process, with nobody at the screen. A schedule or a call from your own system starts it, the steps run in order, and the result arrives in your inbox or in the systems you already use.

• Weekly check of your counterparties' company records

  Build this

  Starts

  Every Monday at 9:00 (Asia/Tokyo)

  Step 1

  For each 会社法人等番号 on your list, get the company's registry record.

  Step 2

  Keep the companies whose 商号, 本店, 資本金の額 or officers changed since the last run.

  Step 3

  Email you the changes, one section per company, with old and new values.

• Monthly usage statement for accounting

  Build this

  Starts

  On the 5th of every month at 9:00 (Asia/Tokyo)

  Step 1

  Get the monthly usage details for the previous month.

  Step 2

  Have an AI step group the 利用明細 lines by property or company.

  Step 3

  Post the totals per record type and the grouped lines to your accounting system's webhook.

• Company record for a new customer, on request

  Build this

  Starts

  When your system calls the workflow's webhook with a 会社法人等番号

  Step 1

  Get the company's registry record for the 会社法人等番号 you sent.

  Step 2

  Stop if no company is found.

  Step 3

  Post 商号, 本店, 会社成立の年月日, 資本金の額 and the officers to your CRM's webhook.

You can run a workflow by hand on every plan, Free included. Schedules and webhook triggers come with the paid plans, from $29 a month.

Once built, one call from your code

Once you have built a method, it is one POST to /v1/runs from your backend, or a tool an AI agent calls over MCP. This is what “Get a company's registry record” would look like.

curl https://api.fous.com/v1/runs \
  -H "Authorization: Bearer $FOUS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "method": "www.touki.or.jp/get_company_record",
    "input": {
      "company_number": "9999-01-000000"
    }
  }'

      }
    ],
    "receipt_number": "2026111200000001"
  }
}

An example with invented data, not a ready-made endpoint. The method exists in your organization once you build it, and its name, inputs and fields follow your request.

The Registry Information Service’s own options

The service's pages describe no API or file exchange. Records are requested on screen, up to 50 at a time, and delivered as PDF files that carry no certification statement or official seal. Beyond the screens it offers a 照会番号 for agencies that accept one, a ZIP download from マイページ and, for a 管理者ID, a CSV of usage per user.

Signing in to the Registry Information Service

The service signs registered users in with an ID番号 of 8 letters and digits and a password. A company receives one 管理者ID, which cannot request records itself, and creates up to 200 利用者ID. With Fous you sign in once through the service's own sign-in with your own 利用者ID: the login is sealed with AES-256, and an expired session is signed back in.

Worth knowing

Every request is charged, even a miss

A record that does not exist still returns a 該当なし notice and is charged. Requesting a record you already hold fetches the latest version and is charged again.

PDFs can be saved for a short time only

A record can be shown and saved on the day it was acquired and the next 3 通常業務日. After that the PDF取得期限 column reads 期間超過 and you request it again.

Properties are found by 地番, not street address

Land is requested by its 地番 and buildings by their 家屋番号, not by the 住居表示 address. The 所在指定 screen has a 地番検索サービス button that looks up a 地番 on a residential map.

Service hours and size limits

Records are available 8:30 to 23:00 on weekdays and 8:30 to 18:00 on weekends and holidays, maps and drawings to 21:00 on weekdays, and none from 29 December to 3 January. Company records over 3 MB stop with 容量エラー.
