Where do you guess you would find this sticker in Japan??
The Kitty says "watch out" ...

I have read somewhere that many tourists from foreign countries
are surprised to find these "too cute" signs and things
here and there while they are travelling in Japan.

You will find this sticker on the doors of some trains.
The other Japanese letters say " otherwise your fingers got pressed!"
"so stay away from the doors!"

Is it a good idea to persuade smalll children or is this too much??
