旭日旗
When hosting an international fleet review at Jeju Island from October 10 to 14, 2018, South Korea requested all participating countries to display only their national flags and the South Korean flag on their vessels, a request apparently aimed at preventing Japan from flying the Rising Sun Flag, which had been the ensign of the Japanese Maritime Self-Defense Force since it was established in 1954. Japan announced on October 5, 2018 that it would be withdrawing from the fleet review because it could not accept Seoul's request to remove the Rising Sun Flag. Japanese officials say the flag is mandatory for Japan’s naval ships under domestic laws and is widely recognized as identification for the Japanese military under an international maritime convention. On October 6, 2018, JSDF Chief of Staff Katsutoshi Kawano said the Rising Sun Flag was the "pride" of Maritime Self-Defense Force sailors, and that the JMSDF would absolutely not go if they had to remove the flag.
