The state hired a contractor to remove the large buoy that washed onto a rocky shoreline near Naalehu.
The bid was awarded to Ka'u Andrade Contracting, Inc. for $28,500 to remove the buoy. The job was completed on May 23. It was cut up in pieces and hauled away.
The buoy didn't have any markings and officials don't know if it was debris from the 2011 tsunami in Japan.
The buoy was found on the shoreline in October 2012. An identical object washed up on a coastline in Canada.
