Japanese Zen scholars such as D.T. Suzuki became well known in the West. Suzuki spent over fifty years teaching Zen to the world with a series of books in English. In the 1960s in California, Aldous Huxley, Alan Watts, and others promoted the philosophy. From there it spread to many parts of the western world. Zen is now well established outside of Japan and China. Many Zen centers exist in the US and Europe.
