I have used Japanese toilets which are sort of boat shaped with some sort of Heath Robinson plumbing arrangement at one end. You need to straddle and it is very difficult in half-mast winter trousers. It is made worse by the number of users who miss.
(You also get toilets in Japan with heated seats and waterfall sounds/birdsong to cover your modesty, and some with built in bidets. It is a country of sublime to the ridiculous.)
