Taiyûinbyô
Taiyûinbyô is a part of the Rinnôji temple complex in Nikko and is known for the mausoleum of the third Tokugawa shogun, Tokugawa Iemitsu. Iemitsu was the grandson of Tokugawa Ieyasu, and it was his wish that his grandfather be memorialized in the most lavish complex of the time, Nikkô Tôshôgû, while he was laid to rest in his own more humble hall nearby. Taiyûinbyô, like Nikko Tôshôgû, was never supposed to be have a specific religious affiliation and included a combination of both Buddhist and Shinto beliefs, but Iemitsu's complex was made into a temple because Nikko Tôshôgû was made a shrine in the Meiji period of the late 19th early 20th century when the government declared that Buddhism and Shinto are separate beliefs and need separate buildings.

Iemitsu's mausoleum is very grand, but compared to Nikko Tôshôgû it truly is very humble. There are fewer buildings, the complex is in the hills behind Nikko Futarasan Jinja, and there is only one hall despite the three gates and two story pagoda which houses his remains. That being said, it’s not like this complex is some small little thing. Like Nikkô Tôshôgû, Taiyûinbyô is filled with lavish carvings, multitudes of gold leaf, and wonderful popping colors. This temple is a massive success in the visions of Iemitsu because the focus is on the complex he commissioned for his grandfather, while his own resting place is off to the side yet boasts the same visual spectacle befitting a shogun of the 17th century. The main hall of Taiyûinbyô is a hall to Amida Buddha while the mausoleum is up the hill to the right. Unlike Nikkô Tôshôgû which allows visitors access to the resting place of Tokugawa Ieyasu, visitors are not allowed to climb the steps to see Tokugawa Iemitsu, likely because of the short but beautiful gate marking the entrance.
