Japanese toilets have bidet systems built into the toilet bowl itself, so users can do their business and clean themselves all without needing to stand up.
Some bidets even incorporate a mild soap, so you're not just rinsing off, but thoroughly cleansing. Other models let you control the temperature of the water so it's not too cold.
In the cold, northern region of Japan, heated toilet seats are a necessity — not a luxury — and this attitude has spread to the Japanese toilet fan base.
Other features include a blow-dry system, air deodorizing, music speakers, glow in the dark options, an air-conditioned toilet rim, and built-in massagers.
Some Neorests will lift the lid if it senses someone is facing away from the toilet (to sit down), but they’ll lift the lid and seat if someone is facing the toilet (to urinate).
For some Japanese toilets, the sink perches atop the toilet tank so the water you use to wash your hands flows into the tank to flush the toilet, which efficiently conserves water.
The most advanced Japanese toilets turn on a UV light after the toilet is used, scouring and disinfecting every inch of the bowl with the light's sanitizing rays.
