The building from this photo, Komyodo Hall, is one of them - it was built in 1701, originally being the temple's Main Hall. One of the most beautiful buildings in the complex, with walls lacquered in red and a specific Japanese irimoya roof, it is designated as an Important Cultural Property and it enshrines the main deity of the Shingon Esoteric Buddhism, Dainichi Nyorai Buddha.
