JFTC merger control process

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.

2021	Z Holdings / LINE merger	Cleared after behavioral commitments around messaging-app data	Cross-border filing parallel with KFTC / TFTC

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).
