The Ibuchi-gumi was a Japanese yakuza family and a subsidiary of the Tojo-kai. Led by Kei Ibuchi, the family was formed in 2005, and the Ibuchi Family plotted against Akinobu Uematsu's Uematsu-gumi and Goro Majima's Majima-gumi after Chairman Yukio Terada decided to base the choice of clan captain solely on revenue generated for the clan. After Ibuchi killed himself, the family was dissolved.
