The Japanese stock market is attracting renewed interest from investors, driven by corporate governance reforms, a focus on improving capital returns, and increased foreign investment. This resurgence is occurring alongside a changing inflation and interest rate environment. A prominent investor, Warren Buffett, has identified opportunities in Japan, with his company Berkshire Hathaway investing significantly in five major Japanese trading companies since 2019. These companies, known as Sogo Shosha, are diversified conglomerates involved in energy, metals, food, shipping, and more, operating across entire supply chains. Buffett views them as similar to Berkshire Hathaway due to their diverse businesses, long-term outlook, attractive valuations, and financial discipline.
Beyond these trading giants, Japanese companies are also playing a crucial role in the artificial intelligence (AI) supply chain. Firms like Ibiden are producing advanced substrates for chip packaging, essential for high-performance AI processors. Ajinomoto, known for its food products, supplies a critical insulating material used in these advanced chip substrates. Other companies involved in the AI ecosystem include Tokyo Electron, a semiconductor manufacturing equipment producer, and Advantest, which develops chip testing systems. Shin-Etsu Chemical provides raw materials and silicon wafers, while Fujifilm is expanding into electronic materials for chip production.
For Israeli investors, exposure to the Japanese market can be achieved through exchange-traded funds (ETFs) and index funds traded on the Tel Aviv Stock Exchange or via foreign brokers. These funds track Japanese indices like the Nikkei 225 or TOPIX, offering a diversified approach rather than selecting individual stocks. The article discusses the differences between these indices and the impact of currency fluctuations, particularly the Japanese yen, on overall returns. Investors must consider factors such as index composition, management fees, and currency hedging strategies when choosing investment products.
Buffett's investment in the five Japanese trading companies, Itochu, Mitsubishi Corp., Mitsui & Co., Marubeni Corp., and Sumitomo Corp., began in 2019 and was publicly disclosed in August 2020. By the end of 2025, Berkshire Hathaway's holdings in these companies were valued at approximately $35 billion, compared to an acquisition cost of about $15 billion. These investments generated around $860 million in dividends in 2025. Buffett has indicated a long-term holding strategy for these investments, potentially spanning decades. The article notes that while the Japanese market has seen significant gains, with the Nikkei 225 rising about 21% year-to-date and 24% over the past 12 months, it has also experienced a correction. The price-to-earnings ratio for the Nikkei 225 is around 17, which is considered moderate compared to the S&P 500's forward P/E of 19, but future returns depend on sustained profit growth and market conditions.
