In the current unstable global market, Warren Buffett's investment philosophy continues to guide many investors. Amid rising geopolitical risks, Buffett's Berkshire Hathaway has been increasing its investment in Japan's five major trading companies, demonstrating its long-term investment resolve. Despite the rising interest rates, Buffett maintains a long-term holding stance, believing these companies play a crucial role in the global supply chain.

Recent reports indicate that Buffett has been gradually building positions in these trading companies since 2020, planning to raise his stake to nearly the regulatory limit of 9.8%. The diversified business structure of these Japanese trading firms enables them to withstand geopolitical and trade conflicts.

Moreover, these firms are actively pushing for share buybacks and increasing dividends, not only benefitting shareholders but also attracting further capital inflow. Investors looking to follow Buffett's footsteps could consider participating through ETFs focused on Japanese stocks.

Overall, Buffett's asset allocation strategy flexibly responds to market uncertainties, focusing on Japanese trading companies, U.S. tech stocks, and short-term U.S. government bonds, providing investors with a balanced approach.
