On 19 November 2019, Shinzo Abe became the longest-serving
prime minister of Japan and surpassed the previous 2,883-day record of
Katsura Tarō. Abe also beat
Eisaku Satō's record of 2,798 consecutive days on 23 August 2020. He resigned for health reasons in September 2020 and was succeeded by Yoshihide Suga. In early 2020, Japan began to suffer from the
COVID-19 pandemic as several countries reported a significant increase in cases by March 2020. Japan and other countries donated masks, medical equipment, and money to China. In June 2020,
Fugaku was declared the most powerful
supercomputer in the world with a performance of 415.53
PFLOPS. Fugaku also ranked first place in computational methods performance for industrial use, artificial intelligence applications, and big data analytics. It was co-developed by the
RIKEN research institute and
Fujitsu. Because of the COVID-19 Pandemic, the
2020 Tokyo Olympics were postponed until the summer of 2021. In September 2021, Suga announced he would not stand in the
Liberal Democratic Party leadership election, effectively ending his term as prime minister. He was succeeded by
Fumio Kishida who took office as prime minister on 4 October 2021. Kishida was elected leader of the ruling Liberal Democratic Party (LDP) a week prior. He was officially confirmed as the country's 100th prime minister following a parliamentary vote. The first general election under the Reiwa era took place on
31 October 2021. The LDP retained its majority despite losing seats. In March 2022, Japan joined
sanctions against Russia following the
Russian invasion of Ukraine as the first Asian country to exert pressure on Russia. In July 2022, former prime minister Shinzo Abe was
assassinated by Tetsuya Yamagami in
Nara. By comparison, Japan had only 10 gun related deaths from 2017 to 2021 and 1 gun fatality in 2021. On 16 December 2022,
Second Kishida Cabinet announced a departure from Japan's defense-oriented policy by acquiring counterstrike capabilities and a defense budget increase to 2% of GDP by 2027. This comes amidst growing security concerns over China, North Korea and Russia. On 1 January 2024, a
magnitude 7.5 earthquake struck
Ishikawa Prefecture in the
Noto Peninsula, which killed 213 people and caused many more injuries. Following the
2024 Japanese slush fund scandal, Japanese Prime Minister
Fumio Kishida warned that three factions of
Liberal Democratic Party (
Seiwa Seisaku Kenkyūkai,
Kōchikai, and
Shisuikai) all announced their intention to dissolve to form a war cabinet. However, several LDP lawmakers were indicted, including incumbent lawmakers
Yasutada Ōno and
Yaichi Tanigawa, who both resigned from the party following their indictments. Kishida became a controversial figure in Japanese politics, and due to his negative approval ratings, stepped down in September 2024 to be replaced as Prime Minister by
Shigeru Ishiba. On 19 January 2024, Japan becomes the fifth country to successfully land on the surface of the
Moon with the
Smart Lander for Investigating Moon (SLIM) lunar lander mission. On 14 August 2024, Kishida announced that he would not stand in
Liberal Democratic Party leadership election due to the lowest approval rating, effectively ending his three-year-term as prime minister, and thereby not seeking re-election in September of the same year. During the LDP leadership election, Kishida initially endorsed Chief Cabinet Secretary
Yoshimasa Hayashi, then, in the second round, whipped votes for
Shigeru Ishiba, who defeated
Sanae Takaichi to become the next party leader and prime minister. Shigeru Ishiba was elected by the National Diet and appointed as Prime Minister by
Emperor Naruhito at Tokyo Imperial Palace on 1 October 2024, becoming the 101st and 25th Liberal Democratic Prime Minister. Ishiba announced key appointments ahead of
Japanese general election, held on 27 October 2024. His Cabinet included rivals from the leadership race, though
Sanae Takaichi's exclusion created internal party friction. Uniting the divided ruling party became a primary focus for Ishiba after the closely contested leadership race.
Nihon Hidankyo, a group of Japan Confederation of A- and H-Bomb Sufferers Organizations, was awarded
2024 Nobel Peace Prize in October 2024 for its efforts to achieve a world free of nuclear weapons. The organization received the award, held in
Oslo,
Norway, on December 10 of the same year. It is one of the second Japanese laureate to win this prize, less than 50 years since former Japanese Prime Minister
Eisaku Satō win this prize in 1974, as well. During his premiership, then-Japanese Prime Minister Shigeru Ishiba has economically moved his country closer to India and South Korea amidst protectionist policies being employed by the
United States of America, while continuing to support
Ukraine during the
Russian invasion that began February 2022, as well as support
Israel during the
Gaza war. After LDP-Komeito coalition lost its majority in the
House of Councillors following the poor result in
2025 upper election, Ishiba initially announced that he planned to remain as Prime Minister, citing the need to see through tariff negotiations with the United States. After a trade deal, on 22 July 2025, it was erroneously reported that Shigeru Ishiba would be resign by early September. Eventually, he announced his intention to resigned as a LDP president and Prime Minister on 7 September 2025. During the
LDP leadership election, Ishiba initially endorsed Chief Cabinet Secretary
Yoshimasa Hayashi, then, in the second round, whipped votes for
Sanae Takaichi, who defeated
Shinjirō Koizumi to become the next party leader and the first female prime minister.
