BBC | Japanese stocks related to tourism and retail fell on Monday after China warned its citizens not to travel to the country as Tokyo and Beijing remain locked in a row over Taiwan.
Japan's Prime Minister Sanae Takaichi, who has been a vocal critic of China and its military activities in the region, suggested this month Tokyo could take military action if Beijing attacked Taiwan.
Shares in Japanese department stores were hit hard, with the parent company of the Mitsukoshi and Isetan chains plunging more than 10%. Other well-known brands like cosmetics company Shiseido also fell sharply.
China has consistently ranked among the top sources of tourists visiting Japan.
In morning trade in Tokyo, shares in department store chain Takashimaya, and the owner of global fashion chain Uniqlo fell more than 5%.
Carriers Japan Airlines and ANA Holdings were also down.
Shares in Oriental Land, the theme park company that runs the Tokyo Disney resort, was around 5% lower.
The share price falls came after the dispute between Beijing and Tokyo has deepened in recent days.
On Sunday, the Chinese government urged its citizens to reconsider studying in Japan, citing risks to their safety and a rise in crimes targeting Chinese people.
China's Education Ministry also told students already based in Japan to closely monitor the security situation.
Last year, more than 100,000 Chinese students were enrolled in educational institutions in Japan, according to a Japanese government survey.
Also over the weekend, Chinese airlines - including China Southern Airlines, China Eastern Airlines, and Air China - offered refunds for flights to Japan.
