Manners at Homes
You might have noticed if you have a Japanese friend or watch anime. Japanese people always take off their shoes before entering the house. So please take off your shoes. Then you say,
お邪魔します。(ojyamashimasu): polite way to say Excuse me/ Pardon me as you enter the house.
お邪魔 (おじゃま/ojyama) literally means in the way.
