Invited to a house in foreign countries, I really hesitate to enter a house with my shoes on.Because we generally take off our shoes at the entrance of a house in Japan. Some inns and hotels, some restaurants and bar, which are often in the Japanese style, requires you to take off your shoes.
When you visit a Japanese friend’s house, take off your shoes on an earthen floor in the house. An apartment house tends to have a little difference in floor heights. So, please be careful.(^^)
Flower decoration at the entrance or on the “tokonoma” is called “mukae-bana” means welcome flower.
Standard Japanese houses are compact, but most of them have space to give both owners and visitors a good time.
