Passage: After the War of Independence and truce called in July 1921, representatives of the British government and the Irish treaty delegates, led by Arthur Griffith, Robert Barton and Michael Collins, negotiated the Anglo-Irish Treaty in London from 11 October to 6 December 1921. The Irish delegates set up headquarters at Hans Place in Knightsbridge, and it was here in private discussions that the decision was taken on 5 December to recommend the treaty to Dáil Éireann.The Second Dáil Éireann narrowly ratified the Treaty. In accordance with the treaty, on 6 December 1922 the entire island of Ireland became a self-governing Dominion called the Irish Free State . Under the Constitution of the Irish Free State, the Parliament of Northern Ireland had the option to leave the Irish Free State one month later and return to the United Kingdom. During the intervening period, the powers of the Parliament of the Irish Free State and Executive Council of the Irish Free State did not extend to Northern Ireland. Northern Ireland exercised its right under the treaty to leave the new Dominion and rejoined the United Kingdom on 8 December 1922. It did so by making an address to the King requesting, "that the powers of the Parliament and Government of the Irish Free State shall no longer extend to Northern Ireland." The Irish Free State was a constitutional monarchy sharing a monarch with the United Kingdom and other Dominions of the British Commonwealth. The country had a governor-general , a bicameral parliament, a cabinet called the "Executive Council", and a prime minister called the President of the Executive Council.
Question: What happened second, Ireland became a self-governing Dominion called the Irish Free State or Ireland rejoining the UK?

Passage: Although Satsunan literally means the south of Satsuma Province, the north-eastern group of the Ōsumi Islands formed Tane Province for a brief period in the 8th and 9th centuries and then were merged into Ōsumi Province. The Tokara Islands and the northwestern group of the Ōsumi Islands belonged to Kawanabe District of Satsuma Province. The Amami Islands paid tribute to the Ryukyu Kingdom to the South until they were put under direct control in the late 16th century, but were conquered in 1609 by the Satsuma Domain. In 1879, the Amami Islands became Ōshima District of Kagoshima Prefecture. The Tokara Islands and the north-western group of the Ōsumi Islands were transferred to Ōshima District in 1897, and then to Kagoshima District in 1973. After World War II, the Tokara and Amami Islands were put under United States military occupation, which formed the Government of the Northern Ryukyus. The Japanese government fiercely contested the Amami Islands being affiliated with the word "Ryukyu", believing that it would lead to a later return of the islands to their control. The Tokara Islands were returned to Japan in 1952, which were followed by the Amami Islands in December 1953.
Question: Which island was returned to Japan last?
