Mari Kushibuchi

Mari Kushibuchi (櫛渕 万里) is a Japanese politician.

Kushibuchi sailed on the Peace Boat for the first time in 1990, and later joined the associated nongovernmental organization as an executive. In 2009, she contested her first House of Representatives election and won Tokyo's 23rd district for the Democratic Party of Japan. She succeeded incumbent Kōsuke Itō. Kushibuchi lost her 2012 reelection bid to Masanobu Ogura. Following the 2022 resignation of Tarō Yamamoto, Kushibuchi returned to the House of Representatives via proportional representation, this time as a member of Reiwa Shinsengumi.

On 1 June 2023, she was suspended from participating in the Diet for 10 days for "irregular behavior" in the lower chamber, which involved holding up a sheet of paper calling the no-confidence motion against Finance Minister Shun'ichi Suzuki a farce, while standing on the rostrum.
