The Oregon Parks and Recreation Department said they have recovered a section of a fiberglass boat up to 30 feet long after it was spotted off the state's coast last week. It has now been towed into Newport Harbour.
The debris, which travelled nearly 6,500 km, is suspected to be from the powerful earthquake and tsunami that hit Japan on March 11, 2011.
Authorities found some specimens of a variety of yellowtail jack fish normally found in Japanese waters, CNN reported.
The remnants of the boat will be dried out, inspected further and taken to a landfill.
The yellowtail jack fish found on the boat will be taken to the Oregon Coast Aquarium, the report said.
