Japanese retailers and tourism operators voiced concern Saturday after China warned its citizens against visiting Japan following Prime Minister Sanae Takaichi's remarks about a potential contingency involving Taiwan. Department stores and travel agencies expressed fears about a possible decline in Chinese visitors, who had been returning since the end of COVID-19 pandemic restrictions a few years ago. Some industry officials said they would closely monitor Beijing's future actions, noting that the Japanese government's response could determine whether the warning results in an actual drop in tourist numbers.
