Kakuzo Okakura was a Japanese scholar. He was from an upper class family and tutored in English and Western thought as a child. He wrote The Book of Tea, a long essay which discusses Teaism, Zen, Buddhism, philosophy and the Japanese tea ceremony and its influence on all aspects of life and society in Japan.
It is a very good read, and I highly recommend reading it.
