Tenkōkō Sonoda (園田 天光光, Sonoda Tenkōkō, 23 January 1919 – 29 January 2015)[1] was a Japanese politician who was a member of the Japanese Diet from 1946–1952.

In 1950, she became the first woman in Japanese political history to have a baby while in office.

[citation needed] Sonoda was born in Tokyo on 23 January 1919.

She was a socialist at first, and belonged to the Japan Socialist Party (the Social Democratic Party Japan; SDPJ) and the Workers and Farmers Party (Maoism) in the Diet, but changed her opinion by herself to be conservative after her marriage to Sunao.

[citation needed] She was a member of the representative committee of the openly revisionist lobby Nippon Kaigi, to which her son-in-law Hiroyuki is also affiliated.
