Japan Tourism And Retail Stocks Tumble Amid Escalating Row With China Over Taiwan. Japan’s tourism and retail sectors were hit hard on Monday as stocks tumbled following China’s warning advising its citizens not to travel to Japan. The alert comes amid a deepening diplomatic row over Taiwan, after Prime Minister Sanae Takaichi suggested Tokyo could consider military action if China attacked the island. Shares in major department store groups — including the parent company of Mitsukoshi and Isetan — plunged nearly 12% while brands such as Shiseido also saw sharp declines. Retailers Takashimaya and Uniqlo’s owner each fell more than 5% and travel-related companies including Japan Airlines, ANA Holdings and Tokyo Disney Resort operator Oriental Land all closed significantly lower. China, a key source of inbound tourists, has further escalated tensions by urging students to reconsider studying in Japan, citing safety concerns and claims of rising crimes targeting Chinese nationals.
