In a Japanese style house you will see Japanese style dining table which are shorter than the usual tables. Those have shorter legs and chairs are not used. People sit on Tatami around the table. In the winter season, Japanese use a heated table called a kotatsu when they sit on tatami in the living room. The kotatsu is said to have developed at Zen Buddhist temples during the middle ages. Originally coal was used for its heat, but these days kotatsu rely on an electric heating element. The top and sides of the kotatsu are covered with a futon to keep the heat in, and a board is placed on top of the futon so that the kotatsu can be used as a table. In traditional Japanese house there many things to be found which are very unique and interesting and makes the environment of the house more beautiful. In a guest room, usually there is a vertical scroll of calligraphy or art for visitors to enjoy. Another fascinating part of Japanese traditional house which makes the visit more enjoyable for the visitors is Ikebana. The traditional style of flower arrangement or Ikebana is a wonderful part of Japanese art culture. It has long been the custom in Japan to place evergreen trees upright in a welcome to gods, and to offer flowers to the Buddha. The Japanese has shown a remarkable appreciation of flowers, valuing them especially for how they mark the cycle of the seasons. Ikebana developed as part of this interaction between people and flowers, probably around the end of the 1400s. So over the centuries, Japan’s Ikebana has refined its techniques and evolved into an advanced art form. This art is distinguished from purely decorative use of flowers by the extreme care taken in choosing every element in each work. Ikebana is now admired and practiced worldwide.
