 is a Japanese writer and politician. She served four terms in the House of Councillors, the upper house of the national Diet, from 1986 until 2010. Her husband is Heisuke Hironaka, a mathematician.
Politician.
Hironaka was first elected to the House of Councillors from the national proportional representation block at the 1986 election as a member of the Komeito party. She was re-elected to a second term as a national PR member at the 1992 election. Between 1993-1994, she was State Minister, Director-General of the Environment Agency in the Hosokawa Cabinet.
Following the breakup of Komeito in 1994, Hironaka was part of the group that formed the New Frontier Party, which itself dissolved in 1997. She contested the Chiba at-large district as an independent at the 1998 election, winning one of the district's two seats. She subsequently joined the Democratic Party of Japan and served as one of the party's vice presidents on several occasions. Hironaka won a second term as a Councillor for Chiba at the 2004 election, this time as an official DPJ candidate. At the July 2010 election, Chiba's representation was expanded to three seats, however the 76 year-old Hironaka was replaced as a DPJ candidate by the younger Hiroyuki Konishi and Ayumi Michi, who finished first and fourth in the ballot respectively. Hironaka contested the election from the national PR block. She was listed 39th on the DPJ's party ticket in the contest for 48 seats, making it realistically impossible for her to retain a seat. The party received enough votes for 16 seats in the election, ending Hironaka's career in the Diet.
During her time in the Diet, Hironaka also served as Director of the Research Committee on International Affairs and Global Warming Issues and a Member of both the Committee on Environment and Official Development Assistance and Related Matters. She has been active internationally, as Vice Chair of Global Environmental Action (GEA), an organizing member of Micro Credit Summit, a member of World Commission on Forests and Sustainable Development, Earth Charter Commission, and Teri (The Energy and Resources Institute)
Hironaka received a B.A. in English from Ochanomizu Women's University and an M.A. in Anthropology from Brandeis University. She has written several books, essays, translations, and critiques on education, culture, society, and women's issues.
