The Second Takumi-gumi is a Japanese yakuza gang affiliated with the powerful Yamaguchi-gumi syndicate.
The Kansai-based gang was founded in 1967 by Masaru Takumi, the longtime second-in-command (wakagashira) and financial overseer of the Yamaguchi-gumi.
Takumi was kumicho of gang's 1000-members until his assassination in Kobe in 1997 by members of the Nakano-kai. His successor, Tadashi Irie, is the current kumicho.
