Tokyo – Warren Buffett’s Berkshire Hathaway has raised its stake in Japanese trading giant Mitsubishi to over 10%, according to an announcement on August 28. The move sent Mitsubishi’s stock price to its highest level since July 2024.
Mitsubishi said that National Indemnity Company (NICO), a subsidiary of Berkshire Hathaway, increased its ownership from 9.74% to 10.23%, officially making Berkshire one of the company’s major shareholders.
This latest move is part of Buffett’s broader investment strategy in Japan. Since 2019, Berkshire Hathaway has invested in five major Japanese trading houses: Mitsubishi, Mitsui & Co., Sumitomo Corp., Itochu, and Marubeni. Over the years, Berkshire has gradually raised its stakes, reflecting Buffett’s signature value-investing approach—targeting companies with attractive valuations and long-term potential.
Following the news, Mitsubishi shares rallied, and the four other trading companies also gained over 1% amid speculation that Berkshire could continue buying more shares.
In a 2023 interview with Nikkei, Buffett said he was “very proud” of these investments. Earlier this year, he reiterated to Berkshire shareholders: “For the next 50 years, we will never think about selling those shares.”
In March, Berkshire Hathaway increased its holdings in all five Japanese trading houses to nearly 10% after the companies agreed to ease ownership limits for foreign investors.
