Founded in 1393, the temple was moved to its current location in 1598, and served as the primary temple of the Tokugawa family. Most of the current temple structure was constructed in 1974, with the exception of the towering red-lacquered Main Gate (Sangedatsumon), which dates back to 1622, and is one of the oldest wooden structures in the city. The temple complex also houses a mausoleum containing the tombs of six Tokugawa shoguns, and a small museum displaying Buddhist scrolls. Also notable are the collection of stone jizo statues, a Himalayan cedar tree planted by President Ulysses S. Grant in 1879, and a giant 15-ton bell (Daibonshi) made in 1673. The temple is included in a number of Tokyo sightseeing tours, including walking tours, biking tours, temple tours, and photography tours.
