Kuri Natsukawa (born 1962) was a Japanese businessman from Tokyo who visited Kabukicho during the 1980s. On 12 December 1988, he was jumped by Taihei Association yakuza Yoshida Iijima, Shunsuke Shoji, and Matsuta Nagai in an alleyway, but he was rescued by the former yakuza Kazuma Kiryu, and Natsukawa gave Kiryu a ruby plate in gratitude for his help.
