The Nikkei 225 stock index rose more than 3,300 points this Thursday, reaching the historic 62,000-yen range for the first time [1].

This surge marks a significant psychological breakthrough for the Tokyo Stock Exchange. The jump suggests a strong return of investor confidence following a period of consecutive holidays in Japan, signaling that global appetite for Japanese equities remains high despite broader volatility.

The index rose about 3,400 points during the morning session [1]. Market analysts said the rally was due to intense buying interest in semiconductor and artificial intelligence stocks [2]. This sector-specific growth coincided with a shift in geopolitical sentiment regarding the Middle East.

Investors reacted positively to perceptions that U.S. diplomatic efforts to end conflict with Iran have reduced overall geopolitical risk [2]. This sentiment created a favorable environment for riskier assets, allowing the Nikkei to climb rapidly as trading resumed.

"It has become an amazing market. There is a buying mood centered on semiconductors. Isn't it an expectation of a 'war-end agreement'?" said a representative from Iwai Cosmo Securities [2].

Despite the record-breaking numbers, some participants expressed caution. The rapid ascent has led to concerns that the market may have overextended its gains in a short window, potentially leading to a correction.

"There are parts that have risen a bit too much, and it is necessary to see how far this momentum will spread," said a market participant [2].

The Nikkei 225 rose more than 3,300 points, reaching the historic 62,000-yen range.

The breakthrough to 62,000 yen reflects a convergence of technological optimism and geopolitical relief. By tying the rally to AI and semiconductor demand, the market is betting on long-term structural growth in tech. However, the reliance on diplomatic progress between the US and Iran suggests that the current peak is sensitive to political developments, meaning any flare-up in Middle East tensions could quickly reverse these gains.
