As an American journalist in Japan, Jake Adelstein uncovered a world unknown to many of the Japanese public, let alone to foreigners: the world of organized crime. For 12 years, he investigated for Japan's largest newspaper, the Yomiuri Shinbun.
In his final story, Adelstein went toe-to-toe with one of the country's most notorious crime bosses, a discovery that led to death threats for him and his family — death threats that have yet to be lifted. His new memoir about his experiences is called Tokyo Vice: An American Reporter on the Police Beat in Japan.
After leaving the paper in 2005, Adelstein was chief investigator for a U.S. State Department-sponsored study of human trafficking in Japan. Today he is considered one of the foremost experts on organized crime in Japan, and works as a writer and consultant in Japan and the United States.
