Demboin has been the residence of the head priest of Senso-ji for generations. In addition to Kyakuden (a building where guests are received) and the entranceway (both constructed in 1777), and Ojoin, a library and school room (built in 1871), Demboin also includes the head priest's sitting room. Previously known as Kannonin or Chirakuin, it took on its present name around the end of the 17th century.
Kyakuden features an image of Buddha Amidha.
Demboin is a place where prayers are offered for the dead, and where the monks perform their practices and ceremonies. The rongi hoyo, a ceremony for those wishing to be ordained as monks where novices are put to a series of questions by high-ranking priests, is performed on occasions such as the anniversary of the death of Saicho (the Sange-e service), who brought the Tendai School of Buddhism to Japan, and of Zhiyi (the Tendai-e service), founder of the Chinese Tiantai School of Buddhism.
Demboin has a garden of some 12,200 square meters, which is currently not open to the public. The garden is said to have been created in the early 17th century by prominent tea master, architect and garden designer Kobori Enshu. Visitors can take in the garden views while walking the path encircling the pond.
