Japan's retail investors have increasingly focused on trading house stocks, which are strongly supported by Warren Buffett, the legendary investor and CEO of Berkshire Hathaway. These stocks are favored for their robust business models and attractive shareholder returns. Buffett, who has shaped his investment philosophy through early experiences such as selling Coca-Cola door to door, advises younger generations, including Gen Z, to understand their strengths, choose the right associates, and not fear mistakes. He continues to advocate for stock investments over real estate, highlighting the superior long-term opportunities in the U.S. stock market, as evidenced by the S&P 500's growth since 1988. Buffett's leadership principles and investment style remain influential, with discussions around replicating his approach gaining attention among investors. Berkshire Hathaway remains a top company on the 2025 Fortune 500 list, reinforcing Buffett's enduring impact on the investment community.
