The Hall That Honors the Founder
Just west of Nigatsu-do stands a compact square hall with a pyramidal roof, the kind called hōgyō-zukuri, where four equal slopes meet at a single point. This is the Kaizan-dō, the Founder's Hall, built to enshrine Rōben (689–773), the monk who served as Todai-ji's first abbot and helped Emperor Shōmu bring the temple into being.
The hall grew in two stages. Its inner sanctuary was raised in 1200 by Chōgen, the priest then rebuilding Todai-ji after the war fires, in the vigorous Daibutsu-yō (Great Buddha style) he had introduced. Half a century later, in 1250, the hall was moved to its present spot below Nigatsu-do and enlarged with an outer bay, giving it the three-bay-square form seen today.
A National Treasure of Architecture and Sculpture
First protected as an Important Cultural Property in 1898, the Kaizan-dō was raised to National Treasure status in 1953. Along with the Great South Gate, it is one of the few surviving works in the Daibutsu-yō manner, a style marked by tie-beams that pierce the columns and by structural timbers left exposed rather than hidden behind a ceiling.
Inside sits the seated figure of Rōben, also a National Treasure and about 92 centimeters tall. The abbot is shown holding a nyoi scepter, and because the statue was long kept as a hidden image, its colors survive unusually well. Behind it stands a figure of Jitchū, Rōben's leading disciple. The building and the sculpture it shelters are counted together among the masterpieces of the Kamakura age.
Seeing the Kaizan-dō
For all but one day of the year the doors stay shut, and Rōben's image remains a secret Buddha. The hall opens on 16 December, the anniversary of the abbot's death, when a memorial service is held and visitors may step inside to see the statue at close range within its enclosing shrine.
On other days the roof and exterior can still be seen from the lane beside the Sangatsu-dō. Todai-ji's upper precinct, where the Kaizan-dō, Sangatsu-dō, and Nigatsu-dō gather on the hillside, rewards the climb away from the Great Buddha Hall with older, quieter buildings and long views back over the city.
