Japan has also led to the transfer of tens of thousands of cultural artifacts to Japan. The question of where these items should be was during the American occupation of Japan.  In 1965, as part of the Basic Relations Treaty between Japan and the Republic of Korea, Japan ceded some 1,400 artifacts to Korea and estimated that the diplomatic matter was closed.  Korean artifacts are kept in the Tekya National Museum and in the hands of many private collectors.  Since the early 1990s, former Korean comfort women have continued to protest against the Japanese government for the obvious historical denial of the crimes of the Imperial Japanese Army and have demanded compensation for their suffering during the war.    Comfort women`s issues should be resolved definitively and irreversibly in a 2015 agreement between the South Korean and Japanese authorities.  However, the agreement reached by the conservative Park Geun-hye government proved extremely unpopular with South Korean society, as the agreement was seen as a denial of the Japanese government`s direct responsibility for the historical issue. The later moon-jae-in administration withdrew from the agreement. Similar differences between South Korea and Japan over Japan`s responsibility for war crimes committed during World War II remain a sensitive issue. According to a study by the United States Library of Congress, «Korean culture was shattered and Koreans had to speak Japanese and adopt Japanese names.»    This policy of name change, called s`shi-kaimei (창개명; 氏) was part of Japanese assimilation efforts.
  This was strongly rejected by the Korean people. The Koreans, who kept their Korean names, were not allowed to enrol in the school, were not served in government offices and were excluded from lists of food rations and other stocks. Faced with this constraint, many Koreans finally complied with the name change regulation. Such a radical policy was considered symbolically significant in the war effort that associated the fate of the colony with that of the Empire.  A number of prominent Koreans working for the Japanese government, including General Ka Shiyoku/Hong Sa-ik, insisted on retaining their Korean names. Another ethnic Korean, Boku Shunkin/Park Chun-Geum (춘금, 朴), was elected to the House of Commons of tekya`s third district in the 1932 parliamentary elections and served two terms without changing his Korean name, but was registered as Chinilpa by the current government of the Republic of Korea. Many Japanese settlers were interested in acquiring farmland in Korea, even before Japanese land ownership was officially legalized in 1906. Governor General Terauchi Masatake facilitated colonization through land reform, which initially proved popular with the Korean population.
