Adrift on a small boat for 15 days, a 77-year-old fisherman has been rescued by another fishing boat in the East China Sea.

Doctors who treated Yoshimoto Ikari quoted him as saying he had only 10 liters of water and no food during the ordeal.

According to the Japan Coast Guard, Ikari went fishing alone aboard his 0.6-ton boat Misawa Maru from the village of Uken on Amami-Oshima Island in Kagoshima Prefecture on the morning of May 21 and failed to return by nightfall.
