The Festival of the Age and the Fire Festival in Kurama
About 2,000 citizens dressed in historical costumes parade from the Imperial Palace to Heian Shrine in a two-kilometer procession. The costumes are precise reproductions of the ones dating from the end of the eighth century to the Meiji Restoration in 1868. Originally, the costume parade started to set the mood for the festival.
