How to use a Japanese washlet toilet (and find the Stop button)
A washlet is a toilet seat with a built-in water spray. Find the Stop button first, press the wash button you want, and adjust the pressure if needed.
What a washlet is
A washlet (a trade name of the maker TOTO) is a toilet seat with a bidet function. It is common in homes, hotels and many public restrooms. The buttons are on a panel beside the seat, on the wall, or on a remote.
Buttons you will often see
TOTO lists these functions on its official page. Names and symbols can differ by model:
- Rear cleansing: washes the rear.
- Front cleansing: a gentler spray for the front.
- Stop: stops the current operation.
- Warm air dryer: dries the area with warm air.
- Flush and light flush: two flush sizes.
- Privacy: plays a sound to cover the sound of use.
- Water pressure and wand position: adjust to your comfort. TOTO says its models have five pressure levels.
How to use it safely
- Sit down first, then press the button.
- Find the Stop button before you press anything else.
- Start with low pressure, then raise it if you like.
- If the spray feels too strong, press Stop and lower the pressure.
If the buttons are in Japanese only
Look at the symbols. If you are not sure what a button does, do not press it, or press Stop. You can also ask the hotel staff, or check the manual for your model.
FAQ
Is it okay to press a button by mistake?

Do all toilets in Japan have washlets?

Does the seat warm up?
Many models have a heated seat, according to TOTO. It may be turned off in some restrooms.
