On the night of Jan. 26, 1985, four hit men from the Ichiwa-kai crime syndicate drove up to an apartment complex in Suita, Osaka Prefecture.

Their target was a man known as Kunihiko Konishi, but who was in fact Masahisa Takenaka, don of Yamaguchi-gumi, the nation's largest underworld syndicate.

Takenaka, accompanied by two bodyguards, soon arrived to visit his mistress, who lived in an apartment rented under the name of Konishi. Shots rang out, killing Takenaka and his henchmen.
