Horaisan Toshogu is considered as the one of the 3 important Toshogu Shrines (Nikko and Kunosan). It was constructed in 1651 by Tokugawa Iemitsu. When he read the book about his grandfather Ieyasu who was born around this area, he decided to donate founding to Horaiji temple and ordered to built Toshogu Shrine here. The main script of this shrine, the statue of Ieyasu, was placed from the Edo castle.
