This is a large collection of unnarrated video of different trains in Japan and of the toilet of the train being flushed. Sometime the trains switch tracks. The poster has also transcribed the announcements from the train loudspeaker. It's a sort of visual review of trains, and their toilets' flushing mechanism and cleanliness.There is poetry in its simplicity. (Linked again in case I did it wrong in the other field.)
