Overview
The Engaku-ji Relic Hall is a Buddhist hall located within the grounds of Engaku-ji Temple, the head temple of the Rinzai Zen sect in Kamakura City, Kanagawa Prefecture. It is renowned as a representative surviving structure of Zen style (Tōryō-yō, or Chinese style) architecture passed down from China during the Kamakura Period. It holds the distinction of being the only National Treasure building designated within Kanagawa Prefecture. Inside, it enshrines relics (the remains of the Buddha, or sharira) believed to have been brought from Song Dynasty China by Minamoto no Sanetomo.
Historical Background
Engaku-ji was founded in 1282 by Hōjō Tokimune, then the Shogunate Regent of the Kamakura Bakufu. He invited Mugak Sobugen to commemorate those who died fighting during the Mongol invasions. The current Relic Hall is believed to be a relocation from the Buddhist hall of “Taihei-ji,” an affiliated temple located in West Mikado-mon, Kamakura City. This transfer occurred during the mid-Muromachi Period (around the 15th century). It faithfully preserves the architectural style of the Kamakura Period, thus transmitting a valuable example of medieval Zen Buddhism architecture to the present day.
Features and Appeal
The structure showcases the pinnacle of Zen style architecture, possessing an elegant simplicity.
- Pinnacle of Zen Style: Throughout the building, unique design elements characteristic of the Zen style can be observed. These include the strongly curved eaves (ken-sori), closely spaced pillars forming a linked window (renko-mado), and fan-shaped rafters (ōgi-taruki).
- Layered Roof Structure: While its exterior gives the appearance of a two-story building with double roofs, the lower level is actually an overhanging porch called mokoshi. Structurally, it is a single-story building equipped with this mokoshi.
- Interlocking Joinery (Tsumegumi): The builders employed intricate joinery (kumimono) not only on top of the pillars but also between them. This technique gives the hall a delicate yet powerful impression.
- Historical Value: As the only National Treasure building remaining in Kamakura, it is an extremely important cultural property for understanding Japanese architectural history from the medieval to the early modern period, as well as the spread of Zen culture.
