The blast on Sunday killed 72 year old former Self-Defense Force member, Toshikatsu Kurihara. Three others near the explosion suffered injuries.
The sources say police discovered what appears to be coil near the site of the blast.
Police suspect Kurihara blew himself up. They are examining his home which was destroyed by a fire the same day.
They quote eyewitnesses as saying that something the suspect was holding against his belly suddenly detonated, shortly after he sat on a park bench.
Police say metal-like remnants were scattered over an area about 40-meters wide.
