Daiju-ji Temple was an especially important temple for the Tokugawa and houses tablets for each successive family head and shogun. It is interesting to note that the tablets for each shogun are as tall as they were. For example, the mortuary tablet of Tokugawa Ieyasu is 159 cm.

When Tokugawa Ieyasu was young, he lost a battle he was involved in, and ran back to this temple and attempted suicide but a priest urged him not to. If Tokugawa had killed himself then and there, the Tokugawa shogunate may have never existed.

If you face the gate from inside Daiju-ji Temple, you'll clearly see Okazaki Castle 3 kilometers in the distance. This view has been purposefully maintained for the past 370 years. The important of both these locations to the Tokugawa is evident.
