Japan's Nikkei rises past 72,000 as AI euphoria persists

Japan's Nikkei 225 rose 1.55% to close at 72,353.96, touching an intraday record of 72,831.73, driven by continued AI-related euphoria and an eighth straight session of gains — its longest winning streak in over three years. The broader Topix gained 1.24% to 4,095.05. PM Takaichi's administration plans a target of about 370 trillion yen ($2.29 trillion) in public and private investment in AI and chips by 2040, though strategists flagged overheating risks with the 14-day RSI above 70.
