State workers removed a boat, apparently from the the 2011 Japanese tsunami, from Queen’s Beach on the Ka Iwi shoreline Thursday.

The 20-foot skiff bearing Japanese characters and vessel registration numbers, washed up earlier in the week.

The state Department of Land and Natural Resources said two large blue plastic bins, which bore identification marks that may be traceable to Japan, were also reported this week.

Hawaii Wildlife Fund volunteers removed one bin from Kamilo Beach on Hawaii island. 

Another bin was found on Kauai at Larsen’s beach. 

Items with identification numbers, Japanese characters, are reported to the National Aeronautical and Atmospheric Administration, which works with the Japan Consulate in Hawaii to attempt to locate the original owner. If the items aren’t claimed, they are disposed of. 

Tsunami generated by a magnitude-9 earthquake March 11, 2011 off Japan’s northeastern coast killed or left missing more than 18,000 people.

The Japanese government estimated that the tsunami swept about 5 million tons of debris into the ocean
