Sannō Matsuri (山王祭?) or the Sannō Festival, is a major Shinto festival in Tokyo, along with the Fukagawa Matsuri and Kanda Matsuri. The Festival takes place annually in June, but involves a procession called Shinkosai in even-numbered years only; annual celebrations encompass a number of activities and celebrations over a week, including the day-long Shinkosai (also called Jinkosai) parade through Chiyoda, Tokyo.
