The {{nihongo||内閣総理大臣官邸|'''Naikaku Sōri Daijin Kantei'''}} or '''Prime Minister's Office''' is the official workplace of the prime minister of Japan. It is commonly referred to as {{Nihongo||首相官邸|Shushō Kantei}}, or simply {{Nihongo||官邸|Kantei}}. {{tlit|ja|Naikaku Sōri Daijin Kantei}} literally translates to "Prime Minister's Office" in English.

Located at Nagata-chō, Chiyoda-ku, Tokyo, it is diagonally adjacent to the National Diet Building. The term {{tlit|ja|Kantei}} is used as a metonym for the office of the prime minister of Japan and for the prime minister's advisors and administration in general.

In addition to being the principal office of the prime minister, the building also serves as the principal office of the chief cabinet secretary and their deputy, the location of Cabinet meetings, and is also the location of a national crisis management center.<ref>{{cite web|url=http://www.kantei.go.jp/foreign/vt/main/04/photo04_1.html|title=Support staff at Kantei|access-date=2009-05-29|publisher=Cabinet Secretariat of Japan}}</ref>

On the fourth floor there is a room where the Cabinet holds meetings, summits, etc. The fifth floor has the Prime Minister's Office, his or her Reception Room, the chief cabinet secretary's office and reception room.<ref>{{Cite web |date=1996-11-08 |script-title=ja:首相官邸へようこそ |url=https://www.kantei.go.jp/ |access-date=2023-12-04 |archive-url=https://web.archive.org/web/19961108090923/https://www.kantei.go.jp/ |archive-date=1996-11-08 |language=ja}}</ref>

===Previous office=== The former office building is now known as the {{Nihongo||内閣総理大臣公邸|'''Naikaku Sōri Daijin Kōtei'''}}, the prime minister's personal residential quarters.

With the evolution of a national parliament after the Meiji Restoration and the establishment of the post of "prime minister of Japan" in 1885, the need for an official prime ministerial residence was felt. On the encouragement of Prime Minister Tanaka Giichi, the first residence was completed on 18 March 1929. It incorporates architectural styles such as Art Deco and expressionist architecture which became popular from the late Taishō period to the early Shōwa period. It was heavily influenced by the architecture of Frank Lloyd Wright, in particular his design for the second Tokyo Imperial Hotel. It is a two-storied mansion designed by Muraji Shimomoto, of the Ministry of the Treasury (now Ministry of Finance).<ref>{{cite web|url=http://www.kantei.go.jp/foreign/vt2/main/00/photo-zentai02.html|title=An Overview of the Prime Minister's Official Residence|access-date=2009-05-29|publisher=Cabinet Secretariat of Japan}}</ref> Prime Minister Tanaka is said to have exclaimed, "This is just like a café, isn't it?",<ref>{{cite web|url=http://www.kantei.go.jp/foreign/vt2/main/01/photo-genkan01.html|title=The Entrance Hall|access-date=2009-05-29|publisher=Cabinet Secretariat of Japan}}</ref> upon seeing the building.

The building was the site of the May 15 incident in 1932 in which prime minister Inukai Tsuyoshi was assassinated. During the February 26 incident in 1936, renegade soldiers attacked the residence in an attempt to assassinate prime minister Keisuke Okada, who managed to hide in a closet. Instead, six people, including his brother-in-law, were killed. One bullet hole was retained from the 1936 event. The incidents gave rise to rumors that the residence is haunted, with the wife of prime minister Tsutomu Hata writing in a 1996 memoir that she saw spirits wearing old military uniforms in the residence's garden.<ref>{{cite web |url=https://www.france24.com/en/live-news/20251230-japan-pm-takaichi-moves-into-haunted-official-residence |title=Japan PM Takaichi moves into 'haunted' official residence|website=France 24 |date=December 30, 2025}}</ref><ref>{{cite web |url=https://www.tokyoweekender.com/art_and_culture/history/the-spooky-history-of-the-japanese-pms-residence/ |title=Coups, Curses and Ghosts: The Spooky History of the Japanese Prime Minister’s Residence |website=Tokyo Weekender |date=October 3, 2025}}</ref>

By the 1990s, the old {{convert|5200|sqm}} building was deemed cramped and insufficient. It underwent seismic retrofitting and internal renovation.<ref>{{cite web |url=https://www.kantei.go.jp/jp/guide/guide01.html |script-title=ja:外観・正面玄関 |website=Prime Minister's Office of Japan |date=May 30, 2020 |archive-url=https://web.archive.org/web/20220427210343/https://www.kantei.go.jp/jp/guide/guide01.html |archive-date=April 27, 2022 |language=ja}}</ref> The building was unoccupied from 2012 to 2021, during the premierships of Shinzo Abe and Yoshihide Suga.<ref>{{cite web |url=https://english.kyodonews.net/articles/-/67688 |title=Takaichi moves into prime minister's official residence |website=Kyodo News |date=December 29, 2025}}</ref>
