A concrete and metal dock torn loose from a fishing port in norther Japan by last year’s tsunami has washed up on an Oregon beach. 

A Japanese Consulate official confirmed that the dock was from Japan. 

USA Today reports: 

A commemorative plaque on the dock showed it was one of four owned by Aomori Prefecture that broke loose from the port of Misawa on the northern tip of the main island, Deputy Consul Hirofumi Murabayashi said from Portland, Ore.

“We were able to confirm from Aomori Prefecture that they don’t wish to have it returned,” he said. “About the other three, of course, we have no idea where they are floating, or if they are sunk somewhere.”

A starfish native to Japan was among the marine life still clinging to the structure after the long voyage…

The dock was initially mistaken for a barge, according to Oregon parks and recreation officials. 

The dock was tested for radiation and those results turned out negative.
