The results of a DNA analysis conducted on remains found floating at Choshi Port on September 22 indicated the body is that of Takuya Ono, a resident of Ushiku City, Ibaraki.
The body, which consisted of an unclothed torso, was found floating between a boat and a wharf. The torso included an irezumi tattoo, which are often sported by underworld figures.
The head, both arms and legs appeared to have been severed with a knife. None of these other parts have yet been found.
Police were alerted to the possibility that the body is that of Ono after receiving a tip from a male acquaintance on September 24.
On August 30, Ono’s father filed a missing persons report with Gifu Prefectural Police after he had been unable to contact his son, police said.
