evidence: The interpretation of Taiwan becoming the Republic of China's '"de jure" territory is supported by several Japanese court decisions such as the 1956 Japan v. Lai Chin Jung case, which stated that Taiwan and the Penghu islands came to belong to the ROC on the date the Treaty of Taipei came into force.[26] Nevertheless, the official position of the Government of Japan is that Japan did not in the Treaty of Taipei express that Taiwan and Penghu belong to the Republic of China,[28] that the Treaty of Taipei could not make any disposition which is in violation of Japan's renouncing Taiwan and Penghu in San Francisco Peace Treaty,[29] and that the status of Taiwan and Penghu remain to be determined by the Allied Powers in the future.[30] [...] "For the purposes of the present Treaty, nationals of the Republic of China shall be deemed to include all the inhabitants and former inhabitants of Taiwan (Formosa) and Penghu (the Pescadores) and their descendants who are of the Chinese nationality in accordance with the laws and regulations which have been or may hereafter be enforced by the Republic of China in Taiwan (Formosa) and Penghu (the Pescadores)."
