Flower arrangement -Ikebana-
Ikebana, or Japanese traditional flower arrangement, was first stylized in the Muromachi period (1333-1563). People had a custom of offering arranged flowers to Buddha. The concept of Ikebana developed into one that expresses something Buddhistic or divine. it also embraces harmony with nature, symbolized by well-balanced three basic sprays, signifying ten(heaven/universe) , jin(mankind), and chi(earth).
Since WW2, modern schools of ikebana such as Shogetsu school, which uses materials other than flowers, have appeared in an attempt to present this traditional flower arrangement as a kind of formation arts. There are about 2,000 ikebana schools at present, including the Ikenobo school, Ohara school and Sogetsu school.
