Berkshire Hathaway BRK.B is planning its second yen-denominated bond offering of 2026, reinforcing its strategy of accessing Japan’s debt market roughly twice a year. The move allows the conglomerate to capitalize on relatively low borrowing costs while managing currency exposure and funding investments in Japanese assets.
The planned issuance comes amid slowing domestic corporate bond sales in Japan, with credit spreads widening from 45.67 basis points in May to 52.37 basis points in November, according to media sources. In April, Berkshire raised ¥272.3 billion ($1.7 billion) through a six-tranche yen bond offering, with maturities ranging from three to 30 years.
The latest financing initiative underscores Berkshire’s continued confidence in Japan, particularly its investments in five major trading houses — Itochu, Marubeni, Mitsubishi, Mitsui and Sumitomo. Since initiating these investments in July 2019, Berkshire has steadily expanded its holdings. By year-end 2025, the combined market value of these stakes reached $35.4 billion against an aggregate cost of $15.4 billion.
According to Berkshire’s 2025 annual report, its yen-denominated borrowings broadly matched the cost basis of its Japanese investments, carrying an average interest rate of 1.2% and a weighted-average remaining life of approximately 5.75 years.
By matching yen liabilities with yen assets, Berkshire creates a natural currency hedge, limiting foreign-exchange risks. The strategy highlights its disciplined capital allocation, strong credit profile and potential to deepen its exposure to Japan’s investment opportunities.
