Credit for the introduction of Lin-chi Zen (called Rinzai) in Japan is traditionally given to the aristocratic priest and traveler Myoan Eisai (1141-1215).8 He began his career as a young monk in the Tendai complex near Kyoto, but in the summer of 1168 he accompanied a Shingon priest on a trip to China, largely to sightsee and to visit the home of the T'ien-t'ai sect as a pilgrim. However, the T'ien-t'ai school must have been a mere shadow of its former self by this time, and naturally enough Eisai became familiar with Ch'an. But he was hardly a firebrand for Zen, for when he returned to Japan he continued practice of traditional Buddhism.
Some twenty years later, in 1187, Eisai again journeyed to China, this time planning a pilgrimage on to India and the Buddhist holy places. But the Chinese refused him permission to travel beyond their borders, leaving Eisai no choice but to study there. He finally attached himself to an aging Ch'an monk on Mt. T'ien-t'ai and managed to receive the seal of enlightenment before returning to Japan in 1191, quite probably the first Japanese ever certified by a Chinese Ch'an master. He was not, however, totally committed to Zen. His Ch'an teacher was also occupied with other Buddhist schools, and what Eisai brought back was a Buddhist cocktail blended from several different traditions.9 But he did proceed to build a temple to the Huang-lung (Japanese Oryo) branch of the Lin-chi sect on the southernmost Japanese island, Kyushu (the location nearest China), in the provincial town of Hakata. Almost as important, he also brought back the tea plant (whose brew was used in China to keep drowsy monks awake during meditation), thereby instituting the long marriage of Zen and tea.
Although his provincial temple went unchallenged, later attempts to introduce this new sect into Kyoto, the stronghold of traditional Buddhism, met fierce resistance from the establishment, particularly Tendai. But Eisai contended that Zen was a useful sect and that the government would reap practical benefits from its protection. His spirited defense of Zen, entitled "Propagation of Zen for the Protection of the Country," argued that its encouragement would be good for Japanese Buddhism and therefore good for Japan.10
