Description:A large plastic bin is the first confirmed piece of marine debris from last year's Japan tsunamis to arrive in Hawaii, the National Oceanic and Atmospheric Administration said Friday.
Meanwhile, Hawaii fishermen spotted a large dock drifting toward Oahu that may also be tsunami debris. A Maui fisherman climbed on the dock and saw Japanese writing. The 30-feet by 50-feet dock was spotted Wednesday off Molokai, heading toward Oahu.(0:20)
