Established in 1691 and later used as a school for the sons of the powerful during the Tokugawa regime, this is one of Tokyo’s handful of Confucian shrines. There’s a Ming-dynasty bronze statue of Confucius in its black-lacquered main hall (Taisei-den), rebuilt in 1935. The sculpture is visible only from 1 to 4 January and on the fourth Sunday in April, but on weekends and holidays the interior of Taisei-den is accessible; at other times you can only look around the shrine grounds.
