The sign of Construction in Japan is very polite

A sign is very important for construction to avoid traffic accidents or confusion.
It should be clear and easy to see and understand.

In Japan, LED sign of a man who is swinging a flag is everywhere which we are forced to recognize him.

The Japanese sign of the construction is not only clear to see but also very polite.
A man in a screen is bowing to you, saying “We are sorry for making you trouble”.
