Nigatsu-do at Todaiji name comes from the fact that the Shuni-e Ceremony is held here during the second month of the lunar calendar. Unfortunately, a fire broke out inside the hall In 1667 in the midst of the ceremony, and the original building was destroyed and had to be reconstructed in 1669. The acoustics of the hall are said to be perfect and with an inner sanctum, outer sanctum and worship hall that make it particularly well-suited for the rituals conducted here. It is also a popular sunset spot, with many fine lanterns dangling from its eaves. Nigatsu-do is a national treasure of Japan.
