In Japan, there are "Japanese" bathrooms and "Western" bathrooms.The Japanese ones are not much more than holes in the ground to squat over.
The Western toilets are much like ours ... except nearly all of them have seat warmers and bidets.
You will rarely find any toilet seat covers (also there are rarely paper towels and most restaurants do not provide napkins). But in many restrooms, there is toilet seat cleaner in the stall so you can clean it before you use it.
And in some places, there is sound - like rushing water or a flushing sound - to cover up the, uh, other noises.
