 Much the same can be said about the names associated with emperors. Though supposedly descended from an unbroken succession of Shintō deities tracing back to Izanagi and Izanami, progenitors of Amaterasu and Susanoo, Japanese emperors, mythic as well as historical, have taken names that were distinctly Confucian in character. This connection has remained throughout Japanese imperial history. In this respect, the Confucian nuances of imperial names in Japan reveal significant limits of Shintō as the sole foundation for all things imperial.
