"Aki Kan" in Japanese may mean empty can, but there is still money in it. You can see them everywhere. Not dancers, Kan Kan Oji San. The old boys who collect up cans put out for recycling to sell on to a recycling company themselves. Some are homeless, some are in it for the extra cash.
The cans are usually carried on a bike. The bike in this picture once carried all of the cans now being flattened on the ground. More daring than Mr. Kenevil, with better balance than a Chinese circus acrobat, see those Oji San go.
