Meanwhile, SoftBank Group rose 0.59% to 6,352 yen (about $40), while Kioxia gained 0.02% to 54,580 yen. Following the market reopening, Japanese tech and semiconductor-related stocks were boosted by strength in overseas AI sectors, though gains in some individual stocks narrowed significantly from early trading.

During the Japanese market closure, global artificial intelligence-related trades continued to heat up, with the Nasdaq 100 Index previously reaching an all-time high. News such as Meta introducing new AI agents and Alibaba launching AI chips further boosted market attention on the AI supply chain.

However, positive news from external markets did not fully translate into sustained gains for Japanese stocks, as rising bond yields put some pressure on market risk appetite. Japan's 10-year government bond yield rose 8 basis points to 3.055% that morning, with the rapid jump in interest rates keeping investors cautious about asset valuations.
