Ikenobo is very well known. Until the Mid-Edo Period it was only for upper class people. Ikenobo was started by a Buddhist priest called Ikenobo Senkei in the 15th century. It uses standing flowers (called "rikka"). It is a Buddhist way of showing the beauty of nature. There are 7 branches. Each branch represents something in nature, e.g. a hill, valley, waterfall etc. Later, in the 17th century, it became simpler and was called "shoka". Shoka uses just 3 branches called "ten" (heaven), "chi" (earth) and "jin" (man).
