Prime Minister Shinzo Abe is set to become the longest-serving Japanese leader in history, breaking a record that has stood for more than 100 years.

Abe will hold office for the 2887th day on Nov. 20, outpacing prewar politician Taro Katsura (1847-1913), who served a total of 2,886 days.

Abe became prime minister in September 2006, with his first administration lasting only for about one year.

His second administration started after the Liberal Democratic Party (LDP) won the Lower House election in December 2012 and took control over the government from the Democratic Party of Japan. He has been in office for about seven years.

Abe overtook former Prime Minister Eisaku Sato's 2,798 days, the longest in the postwar period, in August 2019, becoming the second-longest serving Japanese leader.

Abe's current term as the LDP president will come to a close at the end of September 2021. If he stays in office until August 2020, he will also break Sato's record for uninterrupted service.

"This long-term administration is a result of our hard work every day," Abe told reporters on Nov. 15. "I would like to ensure that (the administration) does not become lax, and will do my best to keep a tight ship."
