Oda-gumi
The is a yakuza organization founded in 1958 by Hideomi "Joji" Oda in Chūō-ku, Osaka, Japan. Joji would go on to join the powerful Yamaguchi-gumi organization under third generation "kumicho" Kazuo Taoka in 1964, rising to become "saiko-komon" under Taoka. 

The deaths of Kazuo Taoka of heart failure in 1981 and the then Yamaguchi-gumi heir apparent Kenichi Yamamoto the following year created a power vacuum in Yamaguchi-gumi leadership. Joji's support for fourth generation boss Masahisa Takenaka in the resulting Yama-Ichi War, coupled with his arrest in Honolulu in 1985 lead to Joji's retirement from the yakuza and his passing of heart failure in 1986.

Yoshio Matsuoka succeeded Joji as the second "oyabun" of Oda-gumi. Matsuoka lead the Oda-gumi until another change in Yamaguchi-gumi leadership as Yoshinori Watanabe retired in 2005 and Shinobu Tsukasa assumed power as the sixth generation head of Yamaguchi-gumi, creating a rift in Oda-gumi membership as members loyal to Tsukasa lieutenant Seiji Takahashi split from Matsuoka's group, leading to Matsuoka's retirement in 2006. 

Matsuoka "wakagashira" Eiji Takano would succeeded Matsuoka as the third generation boss of Oda-gumi with Tsukasa's blessing and repair the rift with Takahashi's faction. The recent split between Yamaguchi-gumi and Watanabe's former Yamaken-gumi organization has again brought Oda-gumi into the spotlight as members of the Yamaken faction, Kobe Yamaguchi-gumi, deliberately crashed a car into Oda-gumi's offices in March 2016. Takano was also arrested on unrelated mail fraud charges in June of 2016.
