What it does

The actor searches the Japan National Tax Agency corporate-number (houjin bangou) publication site by company name, paginates the matches, de-duplicates, and writes one normalized record per company to the run's dataset. Each base record has the official 13-digit corporate number, the registered name, its kana reading, the full registered address, and the prefecture parsed from that address. When includeDetails is on (the default), it also fetches each company's detail page for the official English name and address, the last-update date, the full change history (name changes, address changes, mergers), and a isClosed flag derived from that history. No account or key is required.

Optional paid add-ons attach an English company summary and KYB risk flags read from the change history.

Quickstart

Open the actor, paste this into the input, and press Run. It returns up to 10 companies whose name contains Toyota (in Japanese).

{
  "companyName": "トヨタ自動車",
  "matchType": "partial",
  "maxCompanies": 10
}

Search works best with Japanese or kana text. Use matchType prefix to match names that start with the text.

Input reference

Field	Type	Required	Default	Description
companyName	string	yes	トヨタ自動車	Company name to search for. Japanese or kana works best, for example トヨタ自動車, ソフトバンク, 楽天.
matchType	enum	no	partial	partial (name contains the text) or prefix (name starts with the text).
includeDetails	boolean	no	true	Also collect the official English name and address, last-update date, full change history, and closed/active flag. Turn off for a faster name-and-address-only run.
maxCompanies	integer	no	100	Maximum number of companies to collect.
withAiCompanySummary	boolean	no	false	Paid add-on. English company summary from the record and change history. Requires a paid plan. Billed per usable AI result.
withAiRiskFlags	boolean	no	false	Paid add-on. KYB red flags from the change history (closure, dissolution, mergers, frequent name/address changes). Requires a paid plan. Billed per usable AI result.

If companyName is empty, the run returns a single item with a populated error field and is not charged.

Run via API and CLI

Start a run and wait for it to finish, then read the dataset. Replace <TOKEN> with your Apify API token.

Run synchronously and get dataset items in one call:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~japan-houjin-bangou-scraper/run-sync-get-dataset-items?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"companyName":"トヨタ自動車","matchType":"partial","maxCompanies":25}'

Start a run asynchronously:

curl -X POST "https://api.apify.com/v2/acts/scrapers_lat~japan-houjin-bangou-scraper/runs?token=<TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"companyName":"ソフトバンク","includeDetails":true,"maxCompanies":100}'

Apify CLI:

apify call scrapers_lat/japan-houjin-bangou-scraper \
  --input '{"companyName":"楽天","maxCompanies":10}'

Fetch results

Every run writes to a dataset. Fetch items as JSON, CSV, or Excel by changing format:

# JSON
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=json"

# CSV
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&clean=true&format=csv"

# Paginate large datasets
curl "https://api.apify.com/v2/datasets/<DATASET_ID>/items?token=<TOKEN>&offset=1000&limit=1000"

<DATASET_ID> is returned as defaultDatasetId in the run object. clean=true drops empty and internal fields.

Billing and limits

• Pay per result. You are charged per company record returned (result event). See the pricing tab for the current per-result price.
• Detail enrichment billed separately. With includeDetails on, each company whose official detail page is fetched charges a details event. Turn it off to skip that charge.
• AI add-ons billed separately. withAiCompanySummary and withAiRiskFlags are optional paid events (ai_company_summary, ai_risk_flags) charged only when they produce usable output, and require a paid Apify plan.
• No charge on failure. If no company matches or the source is down, the actor writes a single item with a populated error field and does not charge for it.
• Free Apify plans are capped at 10 companies per run. Upgrade for higher maxCompanies.
• Spend cap respected. Set maxTotalChargeUsd on the run; once reached, the actor stops emitting and charging further billable results.

FAQ and troubleshooting

What language should I search in? Japanese or kana works best. The registry matches registered Japanese company names. English name search is not supported by the source.

Why are nameEnglish and addressEnglish null? The company has not filed an official English name or address with the registry. These are returned only when the company provides them. Missing values are null, never invented.

What is in changeHistory? The official registered change events for the company: name changes, address changes, mergers, and closures, each with an event date and reason. The isClosed flag is derived from these events.

Can I run a faster, lighter search? Yes. Set includeDetails to false to return only corporate number, name, kana, address, and prefecture, without fetching each detail page (and without the details charge).

Do the AI add-ons work on a free plan? No. withAiCompanySummary and withAiRiskFlags require a paid Apify plan and are disabled for free accounts.

Is this an official government tool? No. This actor is independent and has no affiliation with Japan's National Tax Agency. It reads only the publicly available corporate-number publication site.
