The Nikkei 225 Index rose 0.9% to above 51,300 while the broader Topix Index climbed 0.8% to 3,343 on Tuesday, extending gains from the previous session and following Wall Street higher amid a rebound in AI names and hopes for a potential US government reopening. Tech and AI-related shares led the advance, with Kioxia Holdings, SoftBank Group, Fujikura, Lasertec, and Hitachi climbing 2.3% to 5%. In corporate news, Honda Motor (-0.2%) cut its full-year profit forecast amid pressure from US tariffs and global chip shortages, while facing intensifying competition from Chinese electric vehicle makers. On the economic front, Japan recorded a record current account surplus of JPY 4.5 trillion in September as exports outpaced imports.
