Ikebana is the Japanese art of flower arrangement, also known as kadō. The tradition dates back to the 7th century when floral offerings were made at altars. Later they were placed in the tokonoma alcove of a home. Ikebana reached its first zenith in the 16th century under the influence of Buddhist teamasters and has grown over the centuries, with over 1000 different schools in Japan and abroad. The most well-known schools are Ikenobo, Ohara-ryū, and Sōgetsu-ryū.
