One common feature of Japanese traditional houses is that they have many sliding doors. In early times, they sometimes had dividing screens to partition large rooms. These partitions came to be fixed into the walls, but that caused inconvenience, so channel were made allowing the partitions to slide. This is the style seen in modern Japanese houses today. The word shoji was originally the generic term for partitions between rooms, but today it has come to refer mostly to sliding doors made of paper squares glued on a wood lattice. Using the paper on the sliding doors, it allows soft light to pass through them. The living room is the place where the family dines together. The living room usually contains a cabinet called Chadansu. It is used to store and display tea ceremony items such as bowls, cups, and water vessels. They have a combination of open shelves for display and also drawers and sliding doors for storage. The front panels often have nicely grained hardwoods or silk fabric accents. Tea is very popular in Japan. There are many kinds of tea found in Japan. Although tea, ‘O-cha’, was introduced to Japan from China during the Middle Ages, the method of drinking it developed in a uniquely Japanese way. The special quality of Japanese tea is produced by drying the leaves without fermentation. This produces a different taste appears from that of oolong tea, drunk in China and elsewhere, whose leaves are fermented after they are picked in the same way as those of black tea. The drinking of powdered green tea with various rules of etiquette first became popular in the Muromachi Era, and led to the development of tea houses, beautiful tea bowls and other associated arts and crafts. The art of ‘Sado’, the tea ceremony has become a desirable accomplishment for many Japanese.
