Japanese stocks soar, Buffett's one-day unrealized gains nearing $2 billion.

On Monday local time, the Nikkei 225 index rose by over 2,000 points, breaking through the 56,000 point mark for the first time in history - this also pushed the market value of Berkshire Hathaway's Japanese assets, the investments in the five major trading companies, past 41 billion US dollars. Since 2019, Warren Buffett, who has stepped down as Berkshire Hathaway CEO, has made significant bets on Japanese stocks. The sharp rise in the Tokyo stock market on Monday pushed up the prices of related stocks, resulting in a single day unrealized gain of nearly 2 billion US dollars. Combined with the details revealed in Berkshire Hathaway's financial report, the investment cost is estimated to be around 13.8 billion US dollars, which means that this investment has nearly doubled in value.
