Warren Buffett's Berkshire Hathaway has increased its stakes in five major Japanese trading houses—Itochu, Marubeni, Mitsubishi, Mitsui, and Sumitomo—to nearly 10% each, reflecting a commitment to long-term investments in Japan. The total market value of these holdings reached $23.5 billion, with an aggregate cost of $13.8 billion. Buffett, who has been selling U.S. equities, praised the management and capital strategies of these companies, expressing a desire for Berkshire to own them indefinitely.
