People talk extensively about Japanese toilets, for very good reason. In our time in Japan, we've experienced toilets with a wide range of spray functions, even drying action. Many flush automatically, some have heated seats, and often there will be a privacy noise option (the artificial sound of water). The amazing thing is that you'll find these fancy toilets everywhere--from restaurants to train stations to historic sites. And, in public spaces, the bathrooms are consistently immaculate. This is truly a culture committed to clean.
