The Genesis and Scale of the Berkshire Bet
In August 2020, Berkshire Hathaway (NYSE: BRK.A) disclosed initial 5% stakes across Japan’s premier trading houses, commonly known as sogo shosha: Mitsubishi Corporation (TYO: 8058), Mitsui & Co. (TYO: 8031), Sumitomo Corporation (TYO: 8053), Marubeni Corporation (TYO: 8003), and Itochu Corporation (TYO: 8001). According to businesseconomy.com, Berkshire steadily escalated these holdings to as high as 9.8% by March 2025, bringing the total valuation of the Japanese portfolio to approximately $23.5 billion by the end of 2024.
This deployment marked a significant departure from Berkshire’s traditionally U.S.-centric portfolio. The rationale relied heavily on value investing principles. These conglomerates operate expansive global networks spanning energy, metals, food, and textiles, closely mirroring Berkshire’s own diversified structural philosophy. Furthermore, Japan’s low-interest-rate environment allowed Berkshire to finance these equity acquisitions through yen-denominated bond issuances.
The Bottom Line
- Massive Exposure: Berkshire Hathaway holds nearly 10% stakes across all five major Japanese trading houses, totaling roughly $23.5 billion in value.
- Robust Cash Generation: Firms like Marubeni and Itochu continue posting profits, fueled by disciplined capital allocation, share buybacks, and high shareholder payout ratios.
- The Succession Factor: Greg Abel’s upcoming meetings in Tokyo with trading house executives mark a critical juncture for the longevity of the partnership.
Financial Performance and Shareholder Returns
The operational performance of the sogo shosha has largely validated Buffett’s thesis. For the fiscal year ending March 2025, Marubeni Corporation reported a 7% net profit increase to 503 billion yen ($3.5 billion), beating consensus analyst forecasts. Concurrently, Itochu Corporation projected a record net profit of 900 billion yen while maintaining a 50% shareholder payout ratio alongside a 150 billion yen share buyback program.
Historically, diversified conglomerates faced a structural valuation penalty known as the “conglomerate discount.” However, by sharpening their focus on profitable project execution and expanding their information networks, these Japanese firms have shed that discount. Their commitment to shareholder returns, through dividends and share buybacks, has enhanced their appeal.

| Marubeni Corporation | TYO: 8003 | 503 billion yen ($3.5 billion) for FY ending March 2025 (up 7%) | Surpassed analyst forecasts; steady dividend commitment |
| Itochu Corporation | TYO: 8001 | Projected record net profit of 900 billion yen | Maintains 50% payout ratio with 150 billion yen buyback |

Navigating the AI Era and Global Market Shifts
Next month brings a crucial milestone for the partnership: the first meetings in Japan between trading house leadership and Greg Abel, the successor to Warren Buffett as CEO of Berkshire Hathaway. Abel’s engagement will test the operational continuity of an investment strategy that Buffett previously stated he intends to hold for 50 years or longer.

Even so, the fundamental attraction remains intact. According to businesseconomy.com, Berkshire’s endorsement has potentially altered global perception, attracting renewed international capital inflows into Japanese equities and encouraging domestic firms to align more closely with global corporate governance and shareholder return standards.
