Buddhism entered Japan from China, and although there was an almost continuous flow of philosophical and religious thought between the two countries over many centuries, it can be said that Buddhism arrived in three waves: during the Nara period (up to 784 C.E.), Heian period (794?1185 C.E.) and the post-Kamakura period (from 1185 C.E.).
During the Nara period, the main schools that arrived were the Kegon (____) and Hosso (Yogacara; _____s_h) . The Heian period saw the arrival of Tendai (_V__) and the esoteric school of Shingon (____), while the latter wave brought the more faith based schools of Jodo Shu (Pure Land School; ___y_@) and Jodo Shinshu (___y_^; True Pure Land School) and the various Zen Schools (_T_@).
Among the various schools of Buddhism that took root in Japan, perhaps Zen is the most well known overseas, and in many ways Zen and Japanese culture are synonymous. Japanese gardens, tea ceremony and martial arts were all either direct expressions of the Zen spirit or were greatly influenced by it. Perhaps as a result of its overseas fame, the majority of overseas visitors who come to Japan to study meditation will do so at a Zen monastery. The other school that has attracted some overseas interest is Shingon, though not to the same extent as Zen.
Many monasteries offer multi-day meditation courses for the lay community, though only a few cater to non-Japanese speakers. Below is a list of those that have provision for overseas visitors. NB: This list serves only as a 'pointer.' More detailed information is available on the city or prefecture article where the temple is located.
As a resident you are required to participate in the schedule 100% fully, and this can be quite rigorous. In addition to long periods of meditation, there are many hours devoted to physical labor. Visitors should be aware of the schedule before arriving.
Prepare loose clothing suitable for sitting in lotus posture, such as full-length skirts or loose-fitting trousers, and durable clothing for working outdoors. Shorts or clothing that is tight or low cut should be avoided. In addition, as many monasteries are in the mountains, ensure to bring warm clothing, even in the summer.
