Taiyū-in temple is the mausoleum of the third Shōgun Tokugawa Iemitsu, the grandson of Ieyasu.

The temple closely resembles the nearby Tōshō-gū shrine in layout and architecture; however, the temple was intentionally built somewhat more modestly than Tōshō-gū due to Iemitsu's great respect for his grandfather.

Despite the modesty, Taiyū-in temple impresses through its emanation of majesty.
