The Isshiki Giant Lantern Festival takes place at Suwa Shrine in Isshiki, Hazu-gun, Aichi Prefecture. The shrine was established as a branch temple of Suwa Taisha (in Nagano Prefecture) in 1564.

Back then, a monster known as Kaima used to appear and ransack the land and its crops. The villagers offered an Evil-Repressing Sword in front of their household altars and prayed for the monster to be expelled.

The monster did disappear and the ritual became an annual event. Gigantic lanterns about 4m round and 6m high are hung in rows. The people of the area form associations of 6 groups each, which compete with their lanterns. The Isshiki Giant Lantern Festival is held on August 26 and 27 every year.
