In regards Sir Ozone, that story you heard is correct! I heard almost the same exact story from my history teacher a while ago. And interesting back-story filled with romance was that the young Japanese soldier was engaged to be married to his sweetheart after the “war” was supposedly over. The Japanese soldier then set sail for the Philippines to defend against the oncoming Americans. However, the Japanese soldier never once met combat with the enemy, and for many years the soldier remained in his cave ready to protect the Emperor. Many years after the war, that man was discovered, though I don’t know how or exactly when.
The man was then brought back to the Japanese mainland where he was reunited with his friends and family. The woman he had left behind married but early on got devoiced. This set the stage for one of the grandest weddings in Japanese history as the man and woman were finally renewed their commitments and got married.
