In the beginning of June, “Hotarubi no chakai” (tea ceremony of fire flies) and “Tadasuno mori Noryo ichi” (summer evening party in cool-breeze) are held in Shimogamo Shrine. “Hotarubi no chakai” (tea ceremony of fire flies) has been held every year since 1991 by Tadasuno mori Foundation in order to revive the “Noryo chaseki” (summer evening tea party) that had been taken place in Mitarai River inside of Shimogamo Shrine in Meiji period (around 1868 - 1912). On the event day, about 600 fire flies caught in Tadasuno mori Forest are put into a big basket and released to Mitarai River in the evening. You may be amazed by the beautiful lights of fire flies while enjoying the tea ceremony (Noryo chaseki).
