JFTC merger control process
On this page
Overview
JFTC (Japan Fair Trade Commission) merger control is the antitrust gate that sits in parallel with the FIEA tender offer route: any control transaction that crosses domestic-turnover thresholds must be pre-notified to JFTC under the Antimonopoly Act (AMA) and cleared before completion. It belongs in finance because it is the primary regulatory veto for cross-border M&A in Japan and for acquisition-financed deals.

Notification thresholds (post-2010 amendment)
| Transaction | Domestic-turnover trigger |
|---|---|
| Share acquisition (>20% / >50%) | Acquirer-group >20 bn JPY AND target-group >5 bn JPY |
| Merger / company split | Each combining group above the equivalent turnover line |
| Business / asset transfer | Acquired business segment turnover above 3 bn JPY (with acquirer-group >20 bn JPY) |
| Joint share-transfer | Two groups each above the turnover line |
Foreign-to-foreign transactions with Japan-nexus revenue are caught when the domestic-turnover lines are met — JFTC has extraterritorial jurisdiction parallel to EU / China SAMR / US HSR.
Phase I / Phase II review
| Stage | Statutory clock | What happens |
|---|---|---|
| Pre-notification consultation | Informal, weeks-months | Voluntary white-paper meetings, scope of HHI / market-definition discussion. |
| Notification filing | Day 0 | Acquirer files Form to JFTC; public notice on JFTC site. |
| Phase I waiting period | 30 days | JFTC reviews; can be shortened or extended; clearance or move to Phase II. |
| Phase II request for reports | Day 30 → triggered | JFTC issues request; clock resets to 90 days from full response or 120 days from notification (whichever is later). |
| Remedy negotiation | During Phase II | Structural (divestiture) or behavioral remedies; consent decree possible. |
| Clearance or prohibition | End of Phase II | JFTC issues cease-and-desist if remedies inadequate; deal blocked or restructured. |
Gun-jumping prohibitions
Pre-clearance integration is prohibited under AMA Articles 10 / 15 / 16. Practical gun-jumping risks JFTC warns about:
- Pricing coordination between acquirer and target during pendency
- Customer / supplier allocation discussions before clearance
- Sensitive information exchange (price lists, customer pipelines, bid strategies) without clean-team protocol
- Premature operational integration (joint IT, joint procurement, shared sales force)
Remedy: clean-team / outside-counsel review filters, hold-separate covenants, and JFTC-acceptable information barriers — same architecture used for insider trading controls under FIEA Article 166.
Recent case map
| Year | Case | Outcome | Reading |
|---|---|---|---|
| 2021 | Z Holdings / LINE merger | Cleared after behavioral commitments around messaging-app data | Cross-border filing parallel with KFTC / TFTC |
| 2024 | Nippon Steel / US Steel (US side blocked by CFIUS) | JFTC not the binding constraint; CFIUS / national-security overrode | Shows JFTC clearance ≠ deal closure when cross-border FDI veto exists |
| 2024 | Seven & i Holdings / Couche-Tard inbound bid | Defended via takeover-defense + national-security-designation process | Antitrust analysis secondary to government-designation overlay |
| 2024-25 | Various semiconductor / EV-battery JVs | Phase II remedies on overlapping product lines | Pattern of structural divestitures for chip / battery overlap |
What to extract from a JFTC file
- Acquirer-group / target-group definition — full ultimate-parent capture under AMA Article 10
- Domestic turnover figures — last-fiscal-year revenue, Japan-allocated
- Affected product markets — JFTC market-definition methodology (SSNIP-adjacent)
- HHI and HHI-delta — safe-harbor thresholds (HHI<2500 + delta<250, etc.)
- Remedies offered — structural vs behavioral, monitoring trustee design
- Cross-jurisdiction parallel filings — US HSR, EU EUMR, China SAMR, KFTC
Research checklist
- Cross-check JFTC press releases against IB league-table M&A advisers for the transaction.
- Pull the pre-notification consultation summary if published.
- Map notification dates against TOB timeline — JFTC clearance is often a TOB condition precedent.
- Read JFTC annual report for the year’s enforcement priorities and Phase II-rate.
- Check whether the deal also requires sector-license approval (banking, telecom, energy).
