Answer 1

In Japan, guest need to take off their hats or coats before the host opens the door.

Actually, in Japan, it is an etiquette to remove all outerwear (coats, shoes, hats) and carry them in one's hand prior to entering a Japanese house or a building. When leaving, you should not put on your outerwear until the door is closed.
