The name 'Entoku' is also a Japanese era name that ran from August 1489 to July 1492 under Emperor Go-Tsuchimikado.

Entoku-in is noted for Hasegawa Tohaku screen paintings, tying the temple to one of Japan's most famous painters.

The temple is associated with Nene, Toyotomi Hideyoshi's wife, giving Entoku-in a direct connection to a major figure of the Momoyama era.
