The Industrial exposition fair (an exhibition of development of Japanese and foreign cultures) was held in Kyoto that year, where the replica was to be the main monument.

However, failure to buy enough land where the Heian Palace used to stand, the building was built in Okazaki at 5/8 scale of the original.

In 1976, part of the Shrine caught on fire,[1] and nine of the buildings, including the honden, or main sanctuary, burned down.

The architecture design was a reproduction of the Chōdōin (Emperor's palace in the former eras) in 5/8th scale (in length).

The procession of this festival begins at the old Imperial palace, and includes carrying the mikoshi (portable shrines) of Emperors Kanmu and Kōmei to the Heian-jingū.
