What's special about the loo of Hell?

The loo of Hell in Tokyo, Japan

1. Behind the loo is a splendid demon sculpture
2. On the left hand side of the toilet door you'd be able to find a warning notice asking people with a weak heart to beware (yeah you expect people to spot this notice when one is desperate for a wee?)
3. A while after the door is closed the demon will talk to you, and his voice is NOT soft (and, he speaks in Japanese so I couldn't understand it Q_Q)
4. The demon doesn't speak for long, but when he's finished with you he will SWITCH OFF THE LIGHTS IN THE TOILET!!
5. You'd then see some ghostly creatures being projected on the wall

Wicked isn't it?
