Berkshire Hathaway Deepens Japan Strategy with Mitsubishi Stake Increase and Rail Partnership

Berkshire Hathaway has elevated its stake in Mitsubishi Corp. to 10.23%, signaling Warren Buffett's continued confidence in Japan's trading houses. The move, executed through National Indemnity Company, aligns with Berkshire's broader Japan expansion strategy.

Meanwhile, BNSF Railway—a Berkshire subsidiary—has formed a coast-to-coast freight partnership with CSX, despite Buffett dismissing acquisition rumors. The conglomerate's record $344 billion cash pile remains a focal point for investors, as does the planned leadership transition to Greg Abel.

Berkshire shares closed at $755,280, up 0.77%, reflecting steady gains amid cautious capital deployment. The Q2 2025 results underscored this measured approach, with markets closely tracking how Buffett's empire will deploy its unprecedented liquidity.
