Japan: Merger Control

19 February 2014

Introduction Merger control was introduced in Japan by Law No. 54 of 1947, as amended (the Anti-Monopoly Act (AMA)) at the same time as Japan’s first competition rules. The Japan Fair Trade Commission (JFTC) has primary jurisdiction over the enforcement of merger control under the AMA. The AMA provides two types of regulations for business combination: (i) a formalistic regulation which requires a prior notification for transactions that satisfy the relevant thresholds; and (ii) a substantial regulation which prohibits a business combination that will result in restraint of trade in a particular field of trade (relevant market).
