According to Reuters, Japan has decided not to take part in an international fleet review in South Korea next week after Seoul effectively asked Tokyo not to fly its “Rising Sun” flag on a warship. Japan’s relations with both South and North Korea have long been strained by lingering resentment over its 1910-45 colonization of Korea. Japan’s decision comes after South Korea this week asked participating countries not to fly flags at the bow or at the stern of their vessels.
