On June 4, 2010 (April 22 of the lunar calendar), Naoto Kan was elected as the 94th Prime Minister of Japan. Naoto Kan was born on October 10, 1946, a Japanese politician and is currently the 94th Prime Minister of Japan. On June 4, 2010, he served as a representative of the Democratic Party (equivalent to the leader of the party). Born in Ube City, Yamaguchi Prefecture, his native is Kembu Town, Okayama Prefecture. On September 16, 2009, Yukio Hatoyama was successfully elected Prime Minister. Naoto Kan, the acting leader of the Democratic Party, served as Deputy Prime Minister and Minister of the "National Strategy Bureau"; on January 6, 2010, Naoto Kan became Japan's Minister of Finance. On June 3, 2011, the opposition Liberal Democratic Party, Komeito Party, and the Japan Endeavour Party jointly submitted a no-confidence resolution against Naoto Kan's cabinet to the House of Representatives of the Diet. The bill failed to pass, and Naoto Kan's government was temporarily dodged. Naoto Suga (jiān), a politician and member of the House of Representatives of the Democratic Party of Japan, served as Deputy Prime Minister and Finance Minister of Japan after the Democratic Party's election victory in 2009, and has now replaced former Prime Minister Hatoyama as the new Prime Minister of Japan. Former Prime Minister Hatoyama resigned due to the relocation of US military bases in Japan. Naoto Kan was born in Ube City, Yamaguchi Prefecture, and his native name is Kembu Town, Okayama Prefecture.

Naoto Kan came from a working family and was called a "citizen politician" and a "blue-collar politician" by the Japanese media because he did not have the background of political families such as former Prime Ministers Hatoyama, Taro Aso, Yasuo Fukuda, and Shinzo Abe. In college, he was the leader of the Japanese Red Guards. He once invented the Mahjong number calculator; in 1976, he ran for the House of Representatives as an independent candidate and failed three times, but his political talents were discovered by Saburo Eda and recommended him to join the Social Democratic Alliance. Later, he was elected for the fourth time in 1980. After forming the Democratic Party, he ran for party leader four times and lost three times. Before moving into the Prime Minister's Office, Naoto Kan and his family had been renting a house and had no money left to buy a house. Suga served as Minister of Health and Welfare during the Ryutaro Hashimoto government. Later, in September 1996, he cooperated with Yukio Hatoyama to form the Democratic Party of Japan and served as a party representative. Later, he lost to Yukio Hatoyama in the 1999 party representative election. In 2002, Yukio Hatoyama resigned due to electoral defeat and became a party representative again. In 2004, he resigned after being revealed that he had not paid an annuity. Later, after losing the House of Representatives election in 2005 and in 2006, party representatives resigned twice due to money mail problems, but no party representative was elected. On June 2, 2010, Japanese Prime Minister Yukio Hatoyama resigned as prime minister. Analysts pointed out that among the candidates to succeed as prime minister, Deputy Prime Minister and Finance Minister Naoto Kan has a higher voice. The Democratic Party of Japan held a party representative (party leader) election on June 4, 2010. At around 11:23 a.m. Beijing time on the 4th, Naoto Kan, who served as deputy prime minister and finance minister in the Hatoyama cabinet, was successfully elected as the new party representative. At 2:46 p.m., Japan's 94th Prime Minister Naoto Kan was born. On September 149, 2010, Naoto Kan was re-elected as a representative of the Democratic Party and continued to serve as Prime Minister of Japan. Naoto Kan was elected as a representative of the Democratic Party in September 1997 and was re-elected in January the following year. In April 1998, after the Democratic Party merged with the other three parties to form the "New" Democratic Party, Naoto Kan remained as a party representative until he resigned in September 1999. He served as secretary-general of the Democratic Party from September 2000 to September 2002. He was re-elected as a representative of the Democratic Party in December 2002 and resigned in May 2004. After Hatoyama became Prime Minister of Japan in September 2009, Naoto Kan became Deputy Prime Minister and Finance Minister, and served as the acting leader of the Democratic Party. He was elected a representative of the Democratic Party on June 4, 2010 and was elected Prime Minister on the same day. After winning the Democratic Party's representative election in September 2010, Naoto Kan was re-elected as prime minister. He was one of the founders of the Democratic Party of Japan and joined the New Party of Japan in January 1994. In September 1996, he and Yukio Hatoyama and others formed the Democratic Party, and together with Hatoyama served as representative (party leader), and was one of the founders of the Democratic Party. Together with Hatoyama and Secretary-General Ichiro Ozawa, he is regarded as the "troika" of the Democratic Party.
