Berkshire Hathaway (BRK.B) has steadily increased its stakes in Japan’s five trading houses since 2019, with an aggregate investment cost of $13.8 billion by the end of 2024. Yen bond financing has helped limit currency risk and lower borrowing costs, with expectations of $812 million in 2025 dividends against $135 million in interest expenses. Corporate governance reforms and attractive valuations in Japan have made these investments more appealing to foreign investors, enhancing Berkshire’s long-term earnings resilience in an uncertain global landscape.

Japan remains a key revenue driver for both companies, reflecting their long-term commitment to the market.
