Following newly sworn-in Japanese Prime Minister Sanae Takaichi's remarks about Taiwan, China and Japan are reportedly embroiled in their biggest diplomatic dispute in years, prompting travel advice for residents and significantly impacting trade and tourism.
Japanese Prime Minister Sanae Takaichi's comments to parliament this month that a Chinese attack on Taiwan endangering Japan's life could result in a military reaction are thought to be the catalyst for the diplomatic dispute between China and Japan.
Following the comments, East Japan International Travel Service, a Tokyo-based tour operator, said it had lost 80% of its reservations for the rest of the year, while China advised its citizens not to visit Japan because of the diplomatic spat, according to Reuters.

The China-Taiwan dispute centers on Beijing's insistence that Taiwan, which Japan held for many years until 1945, is a part of its territory and has not ruled out using force to gain control.
What was said by the Japanese PM?
For the first time in decades, Prime Minister Sanae Takaichi officially linked a Taiwan Strait crisis to the potential deployment of Japanese troops.
On November 7, Takaichi informed parliament that the use of force against the Chinese-claimed self-ruled island could result in a military reaction from Tokyo and justify the deployment of troops to the island for "collective self-defense."Takaichi was quoted by the AFP news agency as saying that "battleships and the use of force, then that could constitute a situation threatening the survival (of Japan), any way you slice it" if an emergency in Taiwan occurs.
China quickly responded to the comments, threatening more. On Monday, China warned its people not to visit Japan.
Beijing announced on Friday that it had called in Japan's envoy, while Tokyo announced that it had called in China's ambassador following an online post that was deemed "inappropriate" and has since been deleted.
Threat to "cut off" the head of the PM of Japan
Japan's envoy Masaaki Kanai said on Tuesday that the nation's stance on Taiwan has not altered amid the diplomatic back and forth.The remark was made following a meeting between Kanai and Liu Jinsong, the director-general of the Asian affairs division of the Chinese Foreign Ministry. According to Bloomberg, which cited a story by Chinese news outlet The Paper, Jinsong had stated he was "dissatisfied" with the outcome of his meeting with Kanai on Tuesday.
Additionally, Kanai denounced what he called "extremely inappropriate statements" made recently by China's consul general in Osaka, Xue Jian.
In a now-deleted post on X, formerly Twitter, Osaka had threatened to chop off Takaichi's head.
The director general of the agency responsible for Asian and Oceanian relations, Kanai, called for swift action against the diplomat.Repercussions of hostilities between China and Japan
Key commercial links, historical mistrust, and conflict over territorial rivalries are at the center of China and Japan's relationship, which is frequently put to the test by military spending.
Takaichi is a conservative who has a reputation for being a China hawk.
According to a Reuters article that quoted people familiar with the situation, trade has been impacted by the tensions between China and Japan. Beijing's travel warning caused a strong selloff in Japan's largest tourism and retail companies before they recovered some of their losses.
According to the aforementioned individuals, some investment groups, banks, brokerages, and other businesses sent warning messages to employees this week advising them not to travel to Japan.

According to the study, there are worries that China would use commerce as a weapon, as it has done in the past during conflicts with South Korea, Japan, Australia, and other countries.
East Japan International Travel Service, a tour operator based in Tokyo, reportedly lost 80% of its reservations for the rest of the year.
According to Yu Jinxin, vice president of East Japan International Travel Service, a tiny company that specializes in group tours and primarily serves Chinese customers, "this is a huge loss for us," Reuters reported.
Tourism accounts for about 7% of Japan's GDP.
