From everything I have been reading the Japanese are actually happy about the reduction in Chinse tourists and the Koreans seem to be happy to have them, so a win-win for everyone:

Tang and his family were among the influx of Chinese tourists who visited Korea during the holiday period, which began on Feb. 15 and ended on Monday.
Beijing and Tokyo have been embroiled in a diplomatic dispute since November, when Japanese Prime Minister Sanae Takaichi said that Tokyo could respond militarily to a potential attack on Taiwan. In response, Beijing has advised citizens to avoid traveling to Japan.
Korea’s Ministry of Culture, Sports and Tourism estimated that up to 190,000 Chinese tourists visited the country during the nine-day holiday period. The daily average was 44 percent higher than during last year’s holiday window, which ran from Jan. 24 to 29.
The fresh wave of Chinese tourists brought rare optimism to Korea’s retail and tourism sectors, which have been dampened by a consumption slowdown.
In the weeks leading up to the holiday, retailers and tourism operators rolled out intensive marketing campaigns tailored to Chinese tourists, including discounts and gift vouchers linked to Chinese payment platforms such as Alipay and WeChat Pay.
Chinese tourists have traditionally been big spenders, according to Korean tourism industry officials. The most recent government data shows that the average spending per Chinese visitor to Korea reached $1,622 in 2024, compared with the overall foreign visitor average of $1,372.
Even the Korean government has been pulling out all the stops to encourage more spending by Chinese group tourists. On Feb. 15, Minister of Culture, Sports and Tourism Chae Hwi-young visited Myeong-dong, one of Seoul’s main shopping and tourism districts, to inspect facilities for foreign visitors, and called for efforts to foster a more welcoming atmosphere.
