Japanese bamboo culture Bamboo exists closely to Japanese life, and it goes without saying that the Japanese have been using it as a tool for a long time. Bamboo also deeply influenced the traditional culture arts of tea ceremony and flower arrangement. Bamboo has the power to grow one meter a day and is seen to be green all year round. Because of its straight shape and flexibility, and the fact that people believed God was living inside of it, bamboo has been used as a plant that is mysterious and brings good luck for local traditional events. It is said that there are about 620 kinds of bamboo in Japan (1,350 kinds in the world). They are located between tropical and warm climate zones. Japan is the northern end in which bamboo can grow.Although Japanese bamboo is especially high quality and perfect for artifacts, the bamboo that can be used for artifacts is rarely found. Madake is one of the best bamboo for artifacts due to its flexibility, sturdiness and beautiful skin. Kurochiku, Hachiku, Torafutake, Nemagaritake and Mousouchiku are also used often. We could call Japan a country of bamboo.
