Foreign Ownership of Japan Stocks Hits New Record on AI Boom
Nikkei Asia (08/21/26) Nakada, Mayu
The share of Japanese stocks held by overseas investors hit a record for three consecutive years in fiscal 2025, with the greatest increases seen at AI-related companies and those held by activist investors. Overseas investors held 34.7% of all Japanese stocks last fiscal year, according to a shareholder distribution data by the Tokyo Stock Exchange and other exchanges. Nikkei compiled data on foreign ownership, including pension and investment funds, in companies on the TSE's Prime market with book-closings in March. Of the 1,060 for which previous fiscal year comparisons were available, 737 companies saw an increase in such holdings, while foreigners' share fell at 321 companies. Foreign investors "are increasingly picking stocks based on changes in profitability, such as return on equity, instead of scale metrics like market capitalization and liquidity," said Daisuke Uchiyama, a senior strategist at Okasan Securities. Audio equipment maker Foster Electric (TYO: 6794) recorded the biggest increase in the proportion of overseas holdings, rising 24.9 percentage points to reach 44.4%. As of the end of March, Singapore-based fund Axium Capital was Foster's largest shareholder. In June, Yasuto Monden, the fund's chief investment officer, was appointed as an outside director at the annual shareholders meeting. Amid business structure changes and rising expectations of greater shareholder returns, Foster's share price more than doubled over the year through March. The company plans to raise annual dividends to 115 yen (72 cents) this fiscal year, a 35 yen increase from the year before. While not in the top 10 in foreign ownership, digital equipment maker Wacom (TYO: 6727) saw a 13.4 percentage point increase, reaching 55.8% ownership by overseas investors. U.K. fund Asset Value Investors (AVI) increased its stake. "Changes to the Corporate Governance Code have led to more opportunities for corporate decision-making, giving activist investors more room to intervene," said Kohei Onishi, a senior investment researcher at Mitsubishi UFJ Morgan Stanley Securities. Foreign capital inflows to artificial intelligence-related stocks were also notable. Holdings by overseas investors in Furukawa Electric (TYO: 5801) rose 19.6 percentage points, putting it at second place in the ranking. The company saw sales growth, mainly for its fiber-optic cables used in AI data centers, and has forecast a 45% year-on-year rise in net profit for the fiscal year through March 2027. This year, Furukawa was added to the MSCI ACWI, a benchmark index for global equities, giving it an international spotlight. Metal company Mitsui Kinzoku's (TYO: 5706) foreign ownership rose 15 percentage points, ranking ninth. Robust demand for the company's copper foil for AI servers has led to more investors amid the AI boom, bringing in more overseas capital. Of the 33 TSE industry sector indexes, electric appliances had the most companies with increases in foreign ownership, at 68. Overseas investors hold 68.5% of shares in Kioxia Holdings (TYO: 285a). In June, the memory chip maker briefly became the top Japanese company by market capitalization. The next sector was banks, where foreign ownership increased for 64 companies. Investors bought more on expectations of improved earnings due to wider interest rate spreads following rate hikes by the Bank of Japan. Yet, the biggest increase in the sector was only 9.0 percentage points, at Ogaki Kyoritsu Bank (TYO: 8361). In fiscal 2025, net buying of Japanese stocks by overseas investors came to 10.34 trillion yen, near a 22-year high. As of the end of July, their net buying stands at over 7 trillion yen for fiscal 2026.
