Found out that my Air Force Judo sensei and friend passed away on October 27, 2020; Masato J. Yamashita. He lived in San Ramon, CA. Nothing much about his death or obituary. He was a year or so younger than me. We were in boot camp at Lackland AFB, TX then tech school at Chanute AFB, IL then Naha AB, Okinawa until early 1962. Lots of Judo fun in the 2 years together.
