Kyoyou-kai

Kyoyou-kai is an Osaka yakuza group within the Yamaguchi-gumi family. The book identifies its head, Eiju Kim, as a Japanese citizen of Korean ancestry, probably in his late forties. The group enters the narrative chiefly through Kim’s killing, an episode that exposes the possibility of lethal conflict even among people connected by friendship and a shared larger organization.

Identity and Affiliation

Kyoyou-kai was headed by Eiju Kim and belonged to the Yamaguchi-gumi. The account establishes its location and organizational connection but offers little direct description of the group’s internal structure, membership, or business activities. Its place in the story is therefore defined less by a portrait of its operations than by the circumstances surrounding its leader’s death.

Kim’s assailant, Naoto Kametani, headed the Rokkorengo gang, which was also part of the Yamaguchi-gumi. The two men were close friends. Their positions place the killing within a shared yakuza affiliation, rather than presenting it as a straightforward clash between unrelated organizations.

Kim’s Killing

The confrontation took place in front of the Fujiya Hotel. Kim, accompanied by his thirty-year-old underling and driver Kenichi Takanuki, had a heated conversation with Kametani. Kim then broke off the exchange and got into the back of a large black car; Takanuki took the driver’s seat, while Kametani remained beside the vehicle.

As the car pulled into traffic, Kametani fired into the back seat, killing Kim. Takanuki got out and was also shot. Kametani fled on foot but was caught by police after running about two hundred feet and arrested for attempted murder. The narrative reports the arrest in those terms even though Kim had been killed in the attack.

Significance Within the Organization

The book calls the incident highly unusual, noting that violence between yakuza factions was rare. That emphasis gives the killing significance beyond the loss of Kyoyou-kai’s leader: it sets the close friendship between Kim and Kametani against the sudden violence between men who belonged to groups within the same larger organization.

The episode does not explain Kyoyou-kai’s response, any succession after Kim’s death, or the motive for the attack. It instead introduces the killing as an apparently direct homicide while signaling that a fuller account remained to be told. Kyoyou-kai’s limited portrayal reflects that focus: the group is made visible through its leader, his affiliations, and the exceptional event that ended his life.
