The Nikkei 225 Index fell 0.1% to close at 50,324, while the broader Topix Index dropped 0.37% on Monday, extending losses from the previous session, with tourism and retail stocks leading the decline amid rising geopolitical tensions with China. Beijing warned Tokyo against intervening over Taiwan and cautioned Chinese citizens about traveling to Japan, while a Japanese diplomat is set to visit China to help defuse tensions. Travel stocks Japan Airlines and ANA Holdings tumbled 3.8% and 3.1%, respectively. Consumer-related firms including Fast Retailing, Isetan Mitsukoshi, Oriental Land, Ryohin Keikaku, and Sony Group also fell between 3.2% and 11.3%. Meanwhile, Japan's economy contracted 0.4% quarter-on-quarter in the three months to September, reversing a 0.6% expansion in Q2 but beating market forecasts for a 0.6% decline.
