Japanese Buddhist architecture is the architecture of Buddhist temples in Japan, consisting of locally developed variants of architectural styles born in China. After Buddhism arrived from the continent via the Three Kingdoms of Korea in the 6th century, an effort was initially made to reproduce the original buildings as faithfully as possible, but gradually local versions of continental styles were developed both to meet Japanese tastes and to solve problems posed by local weather, which is more rainy and humid than in China. The first Buddhist sects were Nara's six Nanto Rokushū , followed during the Heian period by Kyoto's Shingon and Tendai. Later, during the Kamakura period, in Kamakura were born the Jōdo and the native Japanese sect Nichiren-shū. At roughly the same time, Zen Buddhism arrived from China, strongly influencing all other sects in many ways, including in architecture. The social composition of Buddhism's followers also changed radically with time. Beginning as an elite religion, it slowly spread from the nobility to warriors and merchants, and finally to the population at large. On the technical side, new woodworking tools like the framed pit saw and the plane allowed new architectural solutions.

Tokyō is a system of supporting blocks and brackets supporting the eaves of a Japanese building, usually part of a Buddhist temple or Shinto shrine. The use of tokyō is made necessary by the extent to which the eaves protrude, a functionally essential element of Japanese Buddhist architecture. The system also has an important decorative function. The system is a localized form of the Chinese Dougong that has evolved since its arrival into several original forms.
