SEARCHING FOR JAPANESE POLICE OFFICER.

I am a retired Australian Police Officer and I travelled to Tokyo in early 1980's for a fraud investigation. Inspector Katagiri who was at the time attached to the bodyguard for the Prime Minister was assigned to assist me. I stayed with him and his family and his wife who I think was called Keiko came out later to Sydney to stay with my family. I would like to make contact with him if anyone can assist me, I would imagine that he has retired by now.
