My company sponsored a big beach clean-up near Ketchikan last week.
We sent 60 crew in our tender boats to the local beach to clean up all the trash. We even brought along a Japanese interpreter to identify anything from Japan.
We do not allow plastic bags on our ships, so had to go to the local supermarket to purchase a large quantity of those large American plastic garbage bags.
We filled 300 bags with trash from the beach.
We found plenty styrofoam and paper McDonalds containers (not in Japanese).
We collected thousands of Budweiser and Miller beer cans and bottles (not from Japan).
We found hundreds of shotgun shells (no guns in Japan).
We picked up thousands of soft drink cans - all in English. All bottled in USA.
Nothing Japanese was found.
