Why EDINET matters: Japan's disclosure framework in plain English

Japan's securities-market disclosure framework is governed by the Financial Instruments and Exchange Act (金融商品取引法 / Kin'yū Shōhin Torihiki Hō / FIEA) — the 2007 successor to the Securities and Exchange Law of 1948. The FIEA was modelled on the US Securities Acts of 1933/1934 but adapted to Japan's bank-centric capital market, keiretsu cross-shareholding tradition, and corporate-governance reforms following the 1990s asset-price collapse. The act covers:

• Public offerings + secondary trading (Sections 4 + 24) — annual securities reports (有価証券報告書), quarterly reports (四半期報告書) discontinued for fiscal years starting April 2024, semi-annual reports (半期報告書) reinstated thereafter.
• The 5% rule (Sections 27-23 ~ 27-30) — any entity acquiring 5% or more of a TSE-listed company's voting shares must file a 大量保有報告書 (Large Shareholder Report) within 5 business days. Subsequent ≥1% holdings changes trigger a 変更報告書 (Change Report). This is Japan's equivalent of SEC Schedule 13D (active) / 13G (passive). Distinct from the SEC: the threshold is 5% (vs SEC 5%), the timeline is 5 business days (vs SEC 10 calendar days for 13D and 45 days for 13G), and the filing is electronic-only via EDINET since 2007.
• Treasury share repurchase reporting (Sections 24-6) — every TSE-listed company must file a 自己株券買付状況報告書 (Treasury Share Repurchase Status Report) in months when it executes an open-market buyback under a board-authorized program. Discloses month-end shares repurchased, total amount in JPY, average price, and program-to-date cumulative. Filed within 15 days after month-end.
• Tender offer disclosure (Sections 27-2 ~ 27-22) — public tender offers (TOB / 公開買付け) require a 公開買付届出書 (Tender Offer Statement) plus daily status updates throughout the offer period.
• Officer / director shareholding (Section 24 + Article 19 of the Cabinet Office Order) — directors' and executive officers' personal shareholdings are disclosed inside the annual securities report. Insider trading is regulated separately under FIEA Section 166 (the Japanese 10b-5 analogue).

EDINET is the FSA's mandatory electronic filing system — operated since 2001 (mandatory since 2008 for listed companies), it is the single canonical repository for every FIEA-mandated disclosure. As of 2024, EDINET holds ~3 million filings going back 10+ years, with an average ~80-150 new filings per business day across all doctypes.

What this means in practice for institutional research workflows:

• Activist-investor surveillance: Every meaningful stakebuild by Murakami Fund (村上ファンド), Oasis Management, Dalton Investments, Effissimo Capital Management, ValueAct Capital, Elliott Management, 3D Investment Partners, Argyle Street Management, RMB Capital, Asset Value Investors, and the broader Japan-activist ecosystem hits EDINET within 5 business days.
• Cross-shareholding unwind: Japan's keiretsu cross-shareholding network is collapsing (driven by Corporate Governance Code reforms 2015 + 2018 + 2021). Every unwind transaction by a seimei (life insurer), trust bank, or corporate stakeholder ≥5% of an issuer hits EDINET as a 変更報告書 — the highest-signal data point for tracking the multi-trillion-yen Japan cross-shareholding rotation.
• Buyback signal: Japanese buybacks have surged from ¥3 trillion (2013) to ¥12+ trillion (2024) per fiscal year, driven by ROE-focused activism and TSE's 2023 "PBR < 1.0 disclosure" push. Every monthly buyback execution is in EDINET as a 自己株券買付状況報告書.
• Foreign-fund accumulation: FPI / FII accumulation in TOPIX large-caps is captured in real-time — every time BlackRock, Vanguard, State Street, Capital Group, Norges Bank, GIC, Temasek, or T. Rowe Price crosses 5% in a Japanese name, EDINET is the proof.

For any investor, banker, journalist, IR officer, compliance officer, or quant desk running a Japan strategy, clean programmatic access to EDINET is non-negotiable. This actor is the cheapest reliable JSON source you can plug into your pipeline — billed at the proposed $0.15 per filing institutional tier, matching our HKEX Insider/Short Tracker premium-Asia disclosure pricing.

What you get per filing

Every record returned is a complete EDINET filing snapshot pulled directly from the Japan FSA's official REST API v2 (api.edinet-fsa.go.jp). No HTML scraping, no anti-bot battles, no cookie warm-up — these are the same structured JSON + XBRL documents that power the FSA's public investor pages.

• filer_name_jp — Japanese filer name (e.g. "ブラックロック・ジャパン株式会社", "野村アセットマネジメント株式会社", "村上世彰").
• filer_name_en — Latin transliteration when EDINET provides one (e.g. "BlackRock Japan Co., Ltd."). Many domestic-only filers ship Japanese-only.
• issuer_name — Japanese issuer name when distinct from filer. For 5% rule filings the filer is the holder (e.g. BlackRock) and the issuer is the target company (e.g. Toyota).
• issuer_ticker — 4-digit TSE securities code (e.g. "7203" Toyota, "6758" Sony Group, "9984" SoftBank Group, "7974" Nintendo). EDINET stores it as a 5-digit field with trailing check digit 0; this actor strips that automatically.
• holdings_shares — post-filing total shares held by the filer (parsed from XBRL when enrich_xbrl=true).
• holdings_pct — post-filing percent of voting rights held, as a decimal percentage (e.g. 5.21 = 5.21%). Parsed from the XBRL HoldingRatioOfShareCertificatesEtcAfter element.
• change_pct — change in holdings ratio vs the previous filing — populated on 変更報告書 (change reports) only.
• filing_date — ISO-8601 date EDINET accepted the filing (FSA's submitDateTime field, date-portion).
• doc_type — normalized tag: large_shareholder, large_shareholder_change, treasury_buyback, or officer_trade.
• doc_type_code — raw EDINET docTypeCode (e.g. "350" = 大量保有報告書, "360" = 変更報告書, "220" = 自己株券買付状況報告書).
• doc_type_jp / doc_type_en — human-readable Japanese + English doctype names.
• doc_id — EDINET document ID (e.g. "S100UABC") — globally unique, stable forever.
• doc_url — deep-link to the EDINET viewer for the filing.
• edinet_code — filer's EDINET registration code (the unique Japan FSA filer ID).
• data_source — provenance string identifying the data source on every row.

When enrich_xbrl=true, the actor downloads the XBRL filing instance for each 5% rule filing and parses the post-filing holdings %, total shares, and (for change reports) the delta. XBRL parsing adds ~1.5s per filing (EDINET rate limit ~3 req/s) — disable for fast metadata-only scans.

Field semantics

holdings_pct — what exactly is this?

The XBRL HoldingRatioOfShareCertificatesEtcAfter element. FIEA Section 27-23 defines this as the post-filing percentage of total voting rights held by the filer plus joint-holders (共同保有者), computed as the filer's voting-rights count divided by the issuer's total issued voting rights count (after any treasury-share exclusion). Surface value in decimal-percentage form (e.g. 5.21 = 5.21%).

change_pct — what's the trigger?

FIEA Section 27-25 requires a 変更報告書 (change report) when the filer's holdings ratio moves by ≥1 percentage point from the prior filing, OR when a joint-holder relationship changes, OR when the purpose-of-holding changes (e.g. from "passive investment" to "control / management influence"). The change_pct field is the delta in holdings ratio between this filing and the immediately prior filing in the same filer-issuer chain.

Getting your free EDINET API key

EDINET API v2 launched in late 2023 and closed the previous unauthenticated endpoint shortly after. The new key is free and takes 2 minutes:

1. Visit https://api.edinet-fsa.go.jp/
2. Click APIキーを発行する (Issue API key)
3. Enter email + phone number (the SMS code is for fraud prevention only)
4. Confirm via the verification email
5. Copy the key from your dashboard (format: 40 hex characters)

Rate limit: ~3 requests/second per key. Sufficient for any institutional workflow — a full 30-day all-doctype sweep with XBRL enrichment takes ~5 minutes wall-clock.

Privacy: This actor never logs the key, never persists it to the dataset, and never sends it to any service other than api.edinet-fsa.go.jp. For scheduled runs, set it once as the EDINET_API_KEY env var on your task — it survives across runs and never appears in input logs.

FAQ

Q: Does this actor cover insider transactions by directors / officers? A: For the canonical director / officer transaction signal under Japan FIEA, the equivalent of US Form 4 lives inside the annual securities report (有価証券報告書 / docTypeCode 120) and quarterly reports (四半期報告書 / docTypeCode 140) as the Directors' Shareholding section. Set doc_type=officer_trade to ingest those filings. Note: Japan does not publish a separate per-trade director-transaction register like SEC EDGAR Form 4 — the FSA folded that disclosure into the periodic-report shareholding section in 2014.

Q: How fast is EDINET after a filing is accepted? A: Real-time. FSA accepts the filing, validates the XBRL, and exposes it via the API within ~5 minutes. The EDINET viewer (web UI) typically lags by an additional ~5-15 minutes.

Q: What about TOB / tender offer disclosures? A: TOB-related docTypes (公開買付届出書 etc.) are not in the default coverage of this actor — they live under docTypeCode 040 / 050 and behave differently from the 5%-rule register. If you need them, contact support@thenextgennexus.com — a dedicated japan-tob-tender-offer-tracker actor is on the roadmap.

Q: What does the data look like during Japanese holidays? A: EDINET accepts zero filings on weekends, January 1-3 (New Year), Golden Week (April 29 + May 3-5), Bon Festival closures (mid-August varies by year), and December 31. The actor scans those days normally and gets back 0 results — neither blocks nor charges anything.

Q: Is XBRL parsing reliable? A: For docTypeCode 350 / 360 (the 5% rule register) — yes, ~95% of filings post-2020 publish the canonical HoldingRatioOfShareCertificatesEtcAfter element. Pre-2020 XBRL taxonomy varied slightly; the actor handles all common variants. For the ~5% of filings where the element isn't present (extremely old filings or non-standard filers), holdings_pct returns null — you can still cross-reference the doc_url.

---

Pricing

Proposed: $0.00005 / actor start + $0.15 / filing (institutional Asian disclosure tier — matches our HKEX Insider/Short Tracker). At this price, a typical 30-day large-shareholder sweep (~150 filings) costs ~$22.50 — vs ¥3,000,000+/year for a Bloomberg Japan seat.
