Iehiro Tokugawa (Shinjitai: 徳川家広, Kyūjitai: 德川家廣, Tokugawa Iehiro; born 7 February 1965) is a Japanese author and translator who is the 19th generation and current head of the main Tokugawa clan. His great-great-grandfather was the famed Matsudaira Katamori of Aizu, and his maternal great-great-grandfather was Tokugawa Iesato, the sixteenth head of the Tokugawa clan.

Life
Tokugawa graduated from Keio University before completing a doctorate of economics at the University of Michigan. He is fluent in English, and translated from Japanese a book written by his father, Tsunenari Tokugawa titled Edo no idenshi (江戸の遺伝子) or The Edo Inheritance. He has translated books by Tony Blair, George Soros, George Friedman, Amy Chua, Frances McCall Rosenbluth and Rajiv Chandrasekaran's book 'Green Zone' into the Japanese language. He has also worked for the United Nations Food and Agriculture Organization.

In 2019, Tokugawa attempted to win a seat on the House of Councillors for the Shizuoka District, which he lost. He ran as a member of the Constitutional Democratic Party of Japan, and campaigned on completely decommissioning the Hamaoka Nuclear Power Plant, which was shut down following the Fukushima nuclear disaster in 2011.

Ancestry

Patrilineal descent

Tokugawa's patriline is the line from which he is descended father to son.

The existence of a verifiable link between the Nitta clan and the Tokugawa/Matsudaira clan remains somewhat in dispute.
