[Machine Translation] On December 29, 1991, at around 8:00 p.m., off the Ogasawara Islands, the "Taka," which was participating in an ocean-going yacht race, suddenly capsized due to a rain storm. It was a huge wave. The captain died. The remaining six crew members were transferred to a lifeboat and began drifting aimlessly. The author, who returned alive alone, wrote this record of his 27-day epic struggle for the repose of the souls of his fellow crew members.
