Japan Corporate Registry Daily Changes | New, Updated, Closed

Japan Corporate Registry Daily Diff | New, Changed & Closed Companies (Official Registry Data)

Apify actor that parses the official daily diff of Japan's National Tax Agency corporate registry （法人番号） and emits one dataset item per company registration change — corporate number, registered name, address, entity type, and change type (new / changed / closed / revival) — public registry data, no account or cookies required.

Cost, up front: pay-per-event — $0.10 per actor start + $0.005 per result item. Your maximum charge for a run is fixed before you start: $0.10 + (maxResults × $0.005). The sample run below (12 items) costs $0.16; a full real day at the 2026-11-06 volume (2,617 items) costs $13.19. There is no rental or subscription. If a run returns zero result items, no per-item charge applies — you pay only the $0.10 actor-start charge.

Input

Field	Type	Default	Description
diffPath	string	./data/diff_sample.csv	Path to the NTA daily diff CSV, relative to actor root
date	string	(none)	Optional date label used only in the run log line. It does not filter anything and does not appear in output items
changeTypes	array of strings	[]	Change types to include: 新規 / new, 変更 / changed, 閉鎖 / closed, 復活 / revival, other. Empty = all types
prefecture	string	(none)	Exact match on the Japanese prefecture name, e.g. 東京都. Empty = all prefectures
maxResults	integer	100	Maximum number of results to emit (min 1, max 10000)

No input field is required.

Output summary

Each kept row becomes one dataset item with exactly 34 fields: the 30 registry columns in English plus change_type, process_label, address, and status.

• change_type: new / changed / closed / revival / other
• process_label: same value as change_type
• address: prefecture + city + street_address concatenated
• status: active, or closed when closing_date is set

Sample output (before the pricing section, on purpose)

Real run, real data. This actor's code (version 0.1.0, actor.json build: Dockerfile) was run on the official National Tax Agency diff file dated 2026-11-06. Result: 2,617 items — 1,404 new, 895 changed, 298 closed, 20 revived. The first three items, exactly as emitted:

sequence	corporate_number	name	change_type	address
1	1010001091202	ウエスタン・アセット・マネジメント株式会社	closed	東京都千代田区丸の内１丁目５番１号
2	1010001132674	ＪＰＭ株式会社	changed	千葉県市原市若宮２丁目１９－２４
3	1010001141980	アセアン・トレーディング株式会社	changed	東京都千代田区丸の内１丁目１１番１号

These are public registry records, shown unedited. (This run was executed locally with the actor's own parser on 2026-11-08; the actor is not yet published, so no Apify run ID exists for it. The console test run after publication uses the bundled sample below.)

Bundled-sample run. The same code run on the bundled 12-row fictional sample — the run the Apify console test performs. Result: 12 items (3 new, 6 changed, 2 closed, 1 revival). Five of them:

sequence	corporate_number	name	change_type	address
000001	1010001000001	東京アルファ製作所	new	東京都港区
000003	1010001000003	大阪ベータ商事	new	大阪府大阪市中央区

Dataset format / column layout

No header row. Exactly 30 comma-separated columns per row in NTA daily-diff order:

sequence_number, corporate_number, process_code, correction_code, update_date, change_date, name, name_image_id, entity_type, prefecture, city, street_address, address_image_id, prefecture_code, city_code, postal_code, address_outside_japan, reserved_empty, closing_date, closing_reason, succeeded_corporate_number, change_cause, assignment_date, latest_history_flag, name_en, prefecture_en, city_en, address_outside_japan_en, name_kana, non_display_flag

Fields containing commas or Japanese text are quoted per the real NTA CSV layout.

Process-code classification

Process code	change_type	Meaning
01	new	Newly registered
11, 12, 13, 71	changed	Changed (name, head office, representatives, etc.)
21	closed	Registry record closed
22	revival	Closed registry record revived
other	other	Unknown or unmapped process code

Verifying the output

Every item carries the registry's own sequence number and the official 13-digit corporate number, in the National Tax Agency's own 30-column layout — so any item can be checked line by line against the official daily diff file it came from. The data is an official public registry: no scraping, no accounts, no cookies.

Local development

npm install
npm run test:local

The local test is dependency-free and works without the Apify platform. Syntax-check the actor sources with:

node --check src/main.js
node --check src/diff.js

Pricing

Pay-per-event (PPE) only. Monthly rentals were retired platform-wide. Creators keep 80% of event revenue.

Event	Price
Actor start	$0.10
Per result item	$0.005

Worked examples: the bundled sample (12 items) = $0.10 + (12 × $0.005) = $0.16. A full real day at the 2026-11-06 volume (2,617 items) = $0.10 + (2,617 × $0.005) = $13.19. Your spend cap is maxResults — a run can never return (or charge for) more items than you set.
