Nikko lies at the foot of Mt. Nyoho in the western part of Tochigi, and it is known as the home of the Futarasan Shrine, the Toshogu Shrine and Rinno-ji Temple. It is also home to the Nikko-suginamiki-kaido (Cedar Avenue of Nikko) which has been designated as a natural monument, and it is included as part of the Nikko National Park. The Toshogu Shrine is where the famous shogun Tokugawa Ieyasu is enshrined. The shrine achieved its current state of elaborate luxuriousness when Ieyasu's grandson, shogun Tokugawa Iemitsu, reconstructed it. The engravings on the Yomeimon Gate, redolent in their gorgeous colors, are particularly impressive, and the engravings of the three monkeys in Shinkyu-sha and Nemuri-neko, the sleeping cat, are also well known.
