Summary
Japan's Ministry of Finance and Ministry of Economy, Trade and Industry have formally recommended that South Korean private equity firm MBK Partners suspend its $1.7 billion acquisition of Makino Milling Machine, Japan's world-leading machine tool manufacturer. The suspension recommendation, issued on April 22 and announced by Chief Cabinet Secretary Minoru Gihara, represents only the second government intervention under Japan's Foreign Exchange and Foreign Trade Act since the legislation was strengthened in 2017.
The rejection centers on national security grounds. Machine tools are classified as dual-use items under the Foreign Exchange and Foreign Trade Act—technologies with potential military and civilian applications—and therefore subject to mandatory government review before acquisition by foreign investors. Finance Minister Satsuki Katayama stated to parliament that after examining Makino's role in Japan's defense industrial base, authorities determined the investment posed "a risk of undermining national security." Specifically, the government noted that Makino's products are widely used by manufacturers of Japanese defense equipment, making technology transfer or foreign control a strategic concern.
MBK Partners announced its tender offer plan in June 2025, following an earlier hostile M&A attempt by Japanese motor maker Nidec in April 2025. The acquisition was valued at 275 billion yen ($1.72 billion). Regulatory reviews in Japan and overseas had pushed back the expected tender offer launch to late June 2026. MBK has stated it presented measures to address national security concerns and expressed surprise at the government's recommendation. The firm now has 10 days to decide whether to accept the suspension recommendation.
The timing of Japan's intervention coincides with Prime Minister Sanae Takaichi's government unveiling its biggest overhaul of defense export rules in decades this week, which opens pathways for exports of warships, missiles, and other weapons. Market reaction was swift: Makino's shares declined 9.4% in afternoon trading on the Tokyo exchange. The company said it was gathering information and that no decision had been made regarding its next steps.
