The Imperial Gate of Daikakuji Temple was rebuilt during the Kaei era (1848-1854) of the Edo period (1603-1868). It is a four-legged gate with a gabled roof and eaves gables on the front and back. The entire structure is made of unglazed wood, but only the gable ends are lacquered and decorated with gold gilding. The large chrysanthemum crest is especially distinctive. This gate is a prestigious gate that is opened only when His Majesty the Emperor goes on an excursion or when His Majesty's envoys visit. It is also known as the “Onagori Gate,” and its origin is related to Prince Jishin Irimichi Arisugawa, the last imperial prince of Daikakuji Temple in the late Edo period. The name “Onagorimon” comes from the fact that the prince was ordered by the shogunate to serve concurrently as the abbot of Rinnoji Temple in Edo (Tokyo), and when he left Daikakuji Temple, he repeatedly turned around and left from the Imperial Gate. Prince Jisei-Irudo was deeply attached to Daikaku-ji Temple and continued to wish for the restoration of its temple complex during his tenure at Rinnoji Temple. However, he passed away suddenly in Edo on November 24, 1867, just before returning to Rinnoji. It is said that the tomb of the prince still stands at Rinnoji Temple, facing the direction of Daikakuji Temple in Kyoto.
