It's not different from any other toilet on the planet, except the seat cover that has electronic features. You just drop your bomb into it, then flush it.

But some more hi-end toilet like the Neorest is quite difficult to use because

1. It has auto-open seat cover that use infrared to sense that you are coming to use it.
2. All of its button including flush is electronic button that has Japanese word on it (not push-down valve like normal toilet, Neorest is electronic operated). You got to guess what button is for flushing.
3. From above all the other buttons are Japanese too like bottom washing or heating function so you got to guess it.

But don't be afraid of it! If you could open the seat and flush it, it will be OK.

And there aren't many of this super hi-end toilet too. Most of the place is still use normal toilet that got hi-tech seat cover, that're not different than the one in the US.
