Fumiya Ushijima was a Japanese restauranteur who owned the Ushijima Dining Bar in Sakae, Nagoya and served as chairman of the Sakae Chamber of Commerce. He and the other small business owners of Sakae were staunch supporters of the Nagoya-gumi, of which they were also members, and they kidnapped Ushijima's frequent customer Tatsuo Shinada to prevent him from discovering more about their secret gang. Ushijima's hesitation to kill Shinada allowed for Koichi Takasugi to rescue Shinada from the docks.
