Warren Buffett’s Berkshire Hathaway Inc. has become a major shareholder of Mitsui & Co. after raising its stake, the latest bet that Japan’s trading houses will remain attractive.

The US investor increased its holdings in Mitsui to more than 10% on a voting-rights basis, and may consider expanding its stake even further, according to a statement from the Japanese company on Monday.
