Yukio Hatoyama

In moving towards a more Asia-centered foreign policy, Hatoyama worked towards making relations better with nearby East Asian countries, even saying "the Japanese Islands don't belong to only Japanese". Hatoyama worked to deepen economic integration with the East Asian region, pushing for a free trade zone in Asia by 2020 and proposing Haneda airport as a 24-hour hub for international flights. In January 2010, he welcomed South Korea's president, calling for 'future-oriented' ties, as opposed to recalling the past, in which Japan colonized Korea.

In March 2015, Hatoyama visited Crimea and claimed that the referendum in Crimea was "constitutional."

Hatoyama practices the Transcendental Meditation technique and delivered the Maharishi University of Management commencement address on 23 May 2015 and will be awarded an honorary degree of Doctor of Laws.

On 9 January 2013, Hatoyama expressed a government apology to the victims of Japanese war crimes in China during a visit to Nanjing. He also urged the Japanese government to acknowledge the dispute between the two countries concerning sovereignty of the Diaoyu/Senkaku Islands.

On 21 March 2013, Hatoyama was appointed as the honorary chairman and a senior consultant of Hoifu Energy Group. The firm was named in the Paradise Papers, despite the leak "do not intend to suggest or imply that any people, companies or other entities included in the ICIJ Offshore Leaks Database have broken the law or otherwise acted improperly", according to a disclaimer of International Consortium of Investigative Journalists.

Unlike some of the tax rioters, Hatoyama did not leave the DPJ to join Ichiro Ozawa's People's Life First party, but continued to act within the DPJ to fight against both the consumption tax increase and the restart of nuclear plants. On 20 July 2012 he addressed a crowd of protesters outside the prime minister's residence, saying it was premature to restart nuclear reactors.

In the lead-up to the 16 December 2012 general election the DPJ announced that it would not endorse candidates who did not agree to follow its current policies, including the consumption tax hike and support for joining the negotiations to enter the Trans-Pacific Partnership. On 21 November Hatoyama proclaimed that he would retire from politics. Hatoyama was later expelled from the party.

Hatoyama's popularity soon began to falter after the DPJ struggled to meet the high expectations they set in the midst of a sliding economy. In May 2010 he faced a possible no confidence vote, and on 2 June 2010, Hatoyama announced that he would be resigning as Prime Minister.

On 2 June 2010, Hatoyama announced his resignation as Prime Minister before a meeting of the Japanese Democratic Party. He cited breaking a campaign promise to close an American military base on the island of Okinawa as the main reason for the move. On 28 May 2010, soon after and because of increased tensions from the sinking of a South Korean navy ship allegedly by North Korea, Hatoyama had made a deal with U.S. President Barack Obama to retain the base for security reasons, but the deal was unpopular in Japan. He also mentioned money scandals involving a top party leader, Ichirō Ozawa, who resigned as well, in his decision to step down. Hatoyama had been pressed to leave by members of his party after doing poorly in polls in anticipation of an upper house election in July 2010.

On 5 February 2010, Hatoyama was awarded the Sustainable Development Leadership Award of the Delhi Sustainable Development Summit 2010. The reason for the award was "his effort to confront climate change and leading his government to make it a main issue".

In 2010, Time magazine's "Time 100" elected Hatoyama as No. 6 among the 100 most influential people in the world. It said Hatoyama had "helped change his country from a de facto one-party state into a functional democracy", through the DPJ victory in the 2009 general election.

His younger brother, Kunio Hatoyama, served as Minister of Internal Affairs and Communications under Prime Minister Taro Aso until 12 June 2009. His younger sister-in-law Emily Hatoyama (鳩山エミリ) who is Kunio's wife, an Australian Japanese, was a TV personality in Japan.

The elder Hatoyama became the Democratic Party of Japan's chairman and leader of the opposition from 1999 to 2002, after which he resigned to take responsibility for the confusion that arose from rumors of mergers with Ichirō Ozawa's then Liberal Party. He was Secretary-General of the Democratic Party of Japan (DPJ) before he succeeded Ozawa as party leader following Ozawa's resignation on 11 May 2009. Hatoyama was chosen by fellow party representatives on 16 May 2009, winning 124 of the 219 votes and defeating rival Katsuya Okada.

In December 2009, a finance scandal caused a drop in Hatoyama's popularity. It was revealed that Hatoyama received $4 million in donations that were improperly reported. Most of the money was given by his mother, a wealthy heiress, and some of the reported givers had the names of deceased people. The scandal raised questions about his credibility while also highlighting his privileged background. However, according to NHK in 2010 prosecutors chose not to pursue him citing insufficient evidence of criminal activity, although a secretary was given a suspended prison sentence, and a review panel commented: "it is difficult to believe Hatoyama's assertion he was unaware of the falsifications."

Hatoyama was also faced with the issue of the relocation of the American Futenma Marine Corps Air Base. The United States government hoped that Hatoyama would honor a 2006 agreement to relocate the base to a less populated part of Okinawa and move 8,000 marines to Guam. Some voices in the DPJ demanded that America move its military bases off Okinawa islands altogether. Hatoyama was torn between public opinion on Okinawa and the desire to retain strong ties with Washington.

Hatoyama and his younger brother, Kunio Hatoyama, co-created the party, using billions of yen donated by their mother, Yasuko. Kunio Hatoyama eventually left the DPJ, saying the party had drifted too far to the left from its original centrist roots, and rejoined the Liberal Democratic Party (LDP). Yukio remained with the party through its merger with several other opposition parties in 1998.

Hatoyama is the son of Iichirō Hatoyama, who was Foreign Minister for a time. His mother, Yasuko Hatoyama, is a daughter of Shojiro Ishibashi, the founder of Bridgestone Corporation and heir to his significant inheritance. Yasuko Hatoyama is known as the "Godmother" within the Japanese political world for her financial contributions to both of her sons' political ambitions. In particular, Yasuko donated billions of yen when Kunio and Yukio co-created their previous Democratic Party of Japan (DPJ) in 1996 to help establish her sons' fledgling political party.

First elected to the House of Representatives in 1986, Hatoyama became President of the DPJ, the main opposition party, in May 2009. He then led the party to victory in the August 2009 general election, defeating the long-governing Liberal Democratic Party (LDP), which had been in power for over a decade. He represented the Hokkaido 9th district in the House of Representatives from 1986 to 2012.

Hatoyama ran for a seat in the Hokkaido 9th District and was elected to the House of Representatives in 1986 representing the ruling LDP. In 1993 he left the LDP to form the New Party Sakigake with Naoto Kan, Masayoshi Takemura and Shūsei Tanaka (田中秀征). He and Kan then left to join the newly formed Democratic Party of Japan (1996).

Hatoyama worked as assistant professor (1976–1981) at Tokyo Institute of Technology and later transferred to Senshu University as associate professor (1981–1984).

Hatoyama's son Kiichiro Hatoyama (1976) is married and has given Hatoyama senior two grandchildren.

Hatoyama graduated with a Bachelor of Engineering from the University of Tokyo in 1969 and received a PhD in Industrial Engineering from Stanford University in 1976. He met his wife, Miyuki Hatoyama, while studying at Stanford (Miyuki was working at a Japanese restaurant). The couple married in 1975 after Miyuki divorced her ex-husband. The couple's son, Kiichirō (紀一郎), graduated from the urban engineering department of the University of Tokyo, is a visiting engineering researcher at Moscow State University.

The DPJ's election platform called for re-examining its ties with the United States. As the 1960 Japan–U.S. security treaty entered its 50th year, Hatoyama called for a "close and equal" Japan–U.S. relationship, which meant more independence for Japan's role.

Yukio Hatoyama (鳩山 由紀夫, Hatoyama Yukio, born 11 February 1947) is a former Japanese politician who served as Prime Minister of Japan from 16 September 2009 to 8 June 2010. He was the first Prime Minister from the modern Democratic Party of Japan.

Hatoyama, who was born in Bunkyō, Tokyo, is a fourth-generation politician. His paternal great-grandfather, Kazuo Hatoyama, was speaker of the House of Representatives of the Diet of Japan from 1896 to 1897 during the Meiji era. Kazuo later served as the president of Waseda University. His paternal great-grandmother, Haruko Hatoyama, was a co-founder of what is known today as Kyoritsu Women's University. His paternal grandfather, Ichirō Hatoyama, was a major politician; he served as Prime Minister and was a founder and the first President of the Liberal Democratic Party in 1956. As Prime Minister, he restored diplomatic relations with the Soviet Union, which cleared the way for Japan's membership in the United Nations.
