The Suishin-kai was a Japanese yakuza gang based in Nagasaki, affiliated with the Yamaguchi-gumi. It came to prominence in April 2007 when its former underboss, Tetsuya Shiroo, assassinated the mayor of Nagasaki, Iccho Itoh. The gang voluntarily disbanded shortly after the killing due to intense police scrutiny.
