I vaguely remember reading about that in the newspapers.He was found on some island.I can't remember all of the details.
One Japanese soldier was found on Guam several years after the War. There were several others found before him on Guam. Readers Digest had an article about a Japanese soldier who was watching G.I.s play baseball after the War. He actually threw their baseball back after it was hit into the jungle.
I believe that last Japanese soldier was found in the Phillipine Islands about 35 years after the end of the War. Japan sent a group to the Phillipines to convince him to come out. He returned to Japan but was unable to assimilate back into the culture which had changed so much. He migrated to Brazil I understand.
