The remains of Ieyasu Tokugawa are placed in Okusha-houtou, a 5 meters tall bronze hōtō (jewel stupa, a pagoda version invented in Japan), placed on a foundation with 9 steps. In front of the grave there are three Buddhist accessories used to make offerings, gifts from a Korean king: an evergreen vase, an incense burner with a Chinese lion on top and a candlestick shaped in the form of a crane sitting on a turtle.
Travel tip: Neither the ticket to Tōshōgū Shrine nor the combination ticket (that covers Rinno-ji Temple, Taiyuin Mausoleum and Futarasan Shrine) includes the Shogun's grave.
To visit it, you will need to buy the admission ticket for the Nemuri Neko carving - it costs ¥520, about $7 at the current exchange rate.
