David at The First Word Blog gives a room-by-room description of his apartment in Okinawa. I second his sentiment about Japanese bathrooms.

the whole bathroom is a shower room with a large drain in the centre.  I really wonder why this is not more common in the UK as it is really convenient when you have kids who need showering en masse.  The toilet is similar and to clean you just hose it down…

My toilet room which is separate from the bath (as in ONLY bathing) room has a hose right under the sink. The whole room is waterproof. Genius, really.
