Style home decor and design of Japan as we have seen lately impressed becoming westernized style, is not a true picture of a typical home in Japan there. In Japan a room in the house should be organized as possible because it is a representation of the character of the inhabitants and the environment.
The first thing that most often we know the possible existence of a place to put stuff in the room near the entrance of the house, a sort of space where anyone can leave their shoes and their footwear so as not mixed in the house. It is a culture in Japan a long time ago when the houses they are still using the tatami but today even though many modern homes that are already built but they still adhere to the tradition to put shoes near the entrance to the philosophy of separating the bustle and hubbub outside the house a tranquility gained when we are at home
One thing to consider is the function in the bathroom, they were the Japanese chose to separate toilet and sink for a room as somewhere to wash and to bathe, and do not forget to put the sandals for the shower.
