I have to say, there’s something rather cozy about a warm toilet seat. Definitely got used to that in Japan. I came to expect the full panel of services, too, from waterfall or babbling brook sound effects to various water-jet options. I was a little taken aback the first time I entered and the lid saluted me, opening on its own. And I was just plain amused by a toilet with a lit bowl. Maybe even a little horrified.
Oh, and yes. They flush and close by themselves, too. Any more questions?
How about how perfectly clean those bathrooms were, and the contrast with other countries.
