Japan has expressed regret South Korea hoisted a flag that represents Korea's ancient naval forces at this week's 2018 Jeju International Fleet Review. <br />Japanese broadcaster NHK reported Friday that Tokyo's foreign ministry complained to South Korea over its hoisting of 'Sujagi', a flag that represents Korea's greatest commander, Yi Sun-shin, who fought successful battles against Japan in the 16th century. <br />Japan said South Korea told them the participating countries could only hoist their national flags and the host country's flag, Taegeukgi. <br />Thus, Tokyo says the hoisting of the Sujagi flag contradicts what Seoul had told them. <br />Seoul had asked Japan not to hoist the Rising Sun flag, which is viewed as an emblem of Japan's wartime aggression and imperialism. <br />Japan, refusing to not hoist the flag, ended up not participating in the event. <br />
