Japan doesn’t have paper towels or air dryers in their bathrooms.
Why?
Because everyone carries a handkerchief to dry their hands. They even sell them at airports when you land.

There are too many people that think rinsing hands with water is enough, or that using a urinal doesn’t need hand rinsing much less washing.
Even post-COVID, habits are too hard to break
