Rokkorengo

Rokkorengo is a gang within the Yamaguchi-gumi whose known leader, Naoto Kametani, becomes involved in a fatal confrontation with the head of another group in the same larger organization. The account offers little detail about Rokkorengo’s internal structure or business; instead, it defines the gang through its place in the Yamaguchi-gumi and through the actions of its leader, while showing that affiliation did not prevent violence between connected groups.

Identity and Affiliation

Rokkorengo is identified as a gang belonging to the Yamaguchi-gumi. Its head was Naoto Kametani, who appears in the account as an individual leader rather than as the representative of a described organizational program. The available evidence does not specify Rokkorengo’s size, territory, finances, or internal hierarchy, and does not attribute particular criminal enterprises to it.

Leadership and Conflict

Kametani’s confrontation with Eiju Kim provides the clearest account of Rokkorengo’s place in the larger network. Kim, head of the Osaka group Kyoyou-kai, was also part of the Yamaguchi-gumi; despite their different group affiliations, he and Kametani were close friends. Their heated conversation took place outside the Fujiya Hotel. Kim was accompanied by Kenichi Takanuki, his thirty-year-old underling and driver.

After Kim got into a large black car and Takanuki took the driver’s seat, Kametani fired at the back of the car as it pulled into traffic, killing Kim. Takanuki got out and was also shot; the account does not state his subsequent condition. Kametani fled on foot but was caught by police about two hundred feet away and arrested for attempted murder. The episode establishes Kametani’s leadership and the violent rupture between him and Kim, but it does not show that Rokkorengo’s other members participated or that the attack was ordered by the gang.

Significance Within the Yamaguchi-gumi

The confrontation is presented as unusual because violence between factions within the same larger syndicate was rare. Rokkorengo’s significance in this account therefore lies less in a documented organizational history than in the contradiction embodied by its leader’s conduct: Kametani and Kim were both connected to the Yamaguchi-gumi and were personally close, yet their relationship ended in a shooting. The incident makes visible the limits of organizational affiliation and personal ties as restraints on conflict.
