Even though 72 years have passed since the end of World War II, for Minoru Kawaida, 85, a little known event that happened on the morning of Feb. 6, 1944, remains at the forefront of his mind.

Having studied until 1 a.m., he overslept that morning. He remembers waking up in his home in Tarumizu, Kagoshima Prefecture, and saying, "Oh, no!" after realizing he had broken a promise to his closest friend and classmate, Terushi Kawabata, to go with him to Kagoshima that Sunday by ferry.

The ferry, the 122-ton Tarumizu Maru No. 6, had already left with Kawaida's mother, Toki, Terushi, Terushi's younger brother Akio and an estimated 700 to 800 other passengers.
