Even if you don't avail yourself of the U.S.S. Enterprise style command console allowing you to finely tune how and where your bum is washed, Japan just does toilet business better. Want a clean seat to park your ass on? The American way is to use a toilet seat shaped piece of what feels like thin wax paper, which is guaranteed to slide off the seat and stick to your skin. In Japan, you hold a piece of TP under a nozzle and it sprays a bit of sanitizer, which you then use to wipe the seat. Marvellous.
