Warren Buffett, through his conglomerate Berkshire Hathaway, famously initiated massive investments in Japan's five major general trading companies, known as sogo shosha. These initial and continuing equity acquisitions include prominent Japanese corporations such as Itochu Corporation, Marubeni Corporation, Mitsubishi Corporation, Mitsui & Co., and Sumitomo Corporation. Berkshire has steadily built up these strategic stakes over several years, utilizing favorable low-cost yen-denominated bond issuances to finance the positions while committing to multi-decade holding horizons.
