The Nikkei 225 Index fell 0.9% to around 51,500 while the broader Topix Index lost 0.3% to 3,500 on Thursday, with Japanese shares declining for the second straight session, pressured by losses in technology and financial stocks as profit-taking set in.
Local stocks gave back part of the gains recorded earlier in the week, as the early-year optimism that had lifted risk assets began to fade amid rising geopolitical and economic uncertainty.
Investors also continued to assess the potential impact of China's export controls on military-use products to Japan, which could weigh on the country's industrial and manufacturing sectors.
Heavyweight technology stocks led the decline, with Tokyo Electron down 2.8%, SoftBank Group falling 2.4%, Advantest slipping 1.2%, Lasertec losing 1.5%, and Hitachi retreating 2.0%.
Financial shares also moved lower, including Mitsubishi UFJ (-1.3%), Sumitomo Mitsui (-1.9%), and Mizuho Financial (-1.2%).
