This is a commemorative medal bestowed upon lower-ranking subjects by King Yi of Korea, a member of the Japanese Imperial Family.
The overall outline of the medal forms a five-petalled blossom, depicting the plum blossom (Ihwa) that represents the Korean imperial House of Yi, which also served as the official crest of the Changdeokgung Palace following the annexation of Korea by Japan. The pistil is inlaid with red enamel, while the filaments of the stamens radiate outwards from the centre, with three filaments per petal and the anthers filled with yellow enamel. Inscribed between the pistil and stamens is the text: “In Commemoration of the Royal Sojourn and Bestowal by His Royal Highness Prince Yi Un / July, AD 1934 / Ito Tojiro”. The reverse side features the same design as the obverse, with the exception that it bears no inscription.
Yi Un (AD 1897–1970) was the last Crown Prince of the Korean Empire (Prince Yeong). Appointed Crown Prince in AD 1907 during his childhood, he was subsequently taken to Japan under the guise of study, effectively becoming a political hostage of the Empire of Great Japan. Following the annexation of Korea in AD 1910, his status was downgraded to “King Yi”, receiving treatment equivalent to that of ordinary Japanese imperial royalty. Under Japanese arrangement, he married Princess Masako of Nashimoto-no-miya in AD 1920. Thereafter, he served for an extended period in the Imperial Japanese Army, acting as a political figurehead for the Empire’s assimilation policies and pacification propaganda. Following the Mukden Incident, he was promoted to Lieutenant-Colonel in AD 1932 and subsequently served as a member of the Educational Affairs Section in the Inspectorate General of Military Training. In April AD 1934, he visited Seoul to attend ceremonies at the Chōsen Shrine. His movements during the second half of that year remain unclear; however, the term “sojourn” (chaihaku) on the commemorative medal suggests that he had likely just returned to Japan in July. In AD 1935, he visited Taiwan. He subsequently joined the war of aggression against China as a member of the imperial family, eventually rising to the rank of Lieutenant-General. Following the end of the Second World War, he was stripped of his royal status and Japanese nationality, remaining stranded in Japan for a prolonged period in exile and ill health due to exclusion by Syngman Rhee’s government in South Korea. In AD 1963, he was finally able to return to South Korea at the invitation of the Park Chung-hee administration, eventually passing away in Seoul in AD 1970.
Ito Tojiro, whose birth name was Otani Tojiro, was born in AD 1888, with his year of death unknown. A modern Japanese industrialist, he was originally the second son of Otani Toshiro before being adopted into the family of the prominent Osaka textile merchant, Itoman Sukematsu I, subsequently marrying his second daughter, Banki. He was active in the Kansai textile industry and business community for many years, serving as a director of Itoman Shoten (later renamed Itoman Co., Ltd.), president of Miyagawa Muslin, and holding key positions such as Managing Director and Standing Statutory Auditor at Dai-Nippon Spinning (later Nichibo, now Unitika). As a distinguished entrepreneur, he had already been awarded the Order of the Sacred Treasure, Eighth Class by AD 1911, likely in recognition of his merits as a major taxpayer.
