The Akebono Maru (officially registered Akebono Maru No. 28) was a Japanese fishing trawler that capsized on January 5, 1982. The Mineral Management Service of Alaska reported she sank 50 miles north of the Adak and notes it at the top of its list of "Alaska's Ten Worst Shipping Losses In The Last 20 Years". In total, 32 people died.
Very little is known about her sinking. There are almost no English-language reports of her accident from 1982-1990. The earliest record of the ship is a New Zealand marine index of an accident that occurred on February 16, 1980, when the ship collided with a squid boat off Timaru. At the time, the ship was commissioned by Ferons Ltd.
The Akebono Maru was also the name of a Japanese oil tanker damaged on June 3, 1942 during the Battle of Midway and sunk on March 30, 1944 off Ngeruktabel, Palau.
