Notice seen in the restroom

It must be for foreigners who have never used a toilet before.

'Please go to the restroom'? I'm already in the restroom, though?

Some cultures don't have Western-style toilets, so people from those places don't know how to use them when they go abroad.

Wipe from front to back! This is propaganda from the Back-to-Front faction.

Unfortunately, even with a picture like this, there will still be people who don't understand how to use the toilet properly.

They forgot to mention to always wipe from front to back.

Crumpling used tissue tightly in your fist and throwing it in the toilet is definitely not okay!
