Abstract
Private houses designated as important cultural assets are inherited structural remains. Their value is high in the history of residences. What is called the Japanese style study or drawing room in form is the roots of Japanese private houses and is important in seeing how it has affected home life in its process. Furthermore, as they are scattered over the nation and people are now living in them. As a residence, it is large-sized and intended mainly for inviting guests, but is not being utilized in its fullest extent. It is a big task for the people living in them to keep it well swept and cleaned. It may be due to the fact that families living in them are small in number and are of advanced age. Tour visitors are liable to interfere with the daily life of these people living in these inherited remains.
