Japan's Nikkei index on the Tokyo Stock Exchange rose more than 3% in trading on June 8, 2026, according to Kyodo News. The rally followed a strong advance on Wall Street, driven by optimism that the conflict in Iran could soon conclude.
Investors are hopeful that peace talks or a potential ceasefire will ease geopolitical tensions that have weighed on global markets in recent months. The recovery in U.S. stocks created positive sentiment that spread across Asia, with the Nikkei leading the gains.
Earlier, the Nikkei had come under pressure due to fears of an escalation in the conflict. However, fresh news about the prospects for peace helped the market stage a strong rebound. Analysts suggest that if the situation in Iran improves, Japan's stock market could sustain its upward trend in the near future.
