Toushou Shrines (lit. "Light of the East" or "Illumination of the East") are Shinto shrines in which Tokugawa Ieyasu is enshrined as a holy incarnation of a buddha along the shinbutsu shuugou (merging of Shintoism and Buddhism) beliefs, which put forth the idea that Japanese gods are local manifestations of Indian buddhas come to lead the Japanese people to salvation. Ieyasu is worshiped as such a deity, and around 130 Toushou Shrines are still in existence in Japan.

The Toushou Shrine in Nikkou, the most famous of the Toushou Shrines, was built in 1617 and dedicated to Tokugawa Ieyasu when his son Tokugawa Hidetada was shogun of Japan. Five structures in the shrine complex are National Treasures of Japan. A bronze urn enshrined there contains Ieyasu's remains.

Another Toushou Shrine is located in the city of Shizuoka in Shizuoka Prefecture on Mount Kunou. It was Ieyasu's original burial site and thus the oldest Toushou Shrine in the country.

A third Toushou Shrine is located on Mt. Hourai in Shinshiro City, Aichi Prefecture. It was built by the third Tokugawa shogun, Tokugawa Iemitsu, and completed in 1651.

These three shrines are known as the 'Three Great Toushou Shrines.'

In total there around around fifty Toushou Shrines around Japan, including:

- Shiba Toushou Shrine located in Minato Ward, Tokyo
- Nagoya Toushou Shrine located in Nagoya, Aichi Prefecture
- Sendai Toushou Shrine located in Sendai, Miyagi Prefecture
