Japanese super toilets seem to be most advanced in the world.
Today, the diffusion rate of super toilet, known as “warm-water cleaning toilet seats,” is 60 % in Japan.
A warm-water cleaning toilet seat basically has a nozzle that squirts warm water to wash behinds.
You can adjust the water pressure and the position of the nozzle with a controller on the seat or a panel installed on a wall by the seat.
Also a warm-water cleaning toilet seat is equipped heater in the seat, so it does not get cold during winter.
This one on the picture has a dryer and massage features.
More advanced one has a new system that detects someone standing in front of the toilet and automatically opens the seat.
This is JAPAN Style!
