Owase Shrine’s famous festival is sometimes called a ‘Hadaka Matsuri (Naked Festival)’, but usually is known as the ‘Yaaya Matsuri’ due to the shouting of the young festival participants. It is a festival in which crowds of men dressed in white hold lanterns while they collide violently in narrow streets. Throughout the night, the event is accompanied by the sounds of taiko drums and flute music played by other townspeople. Afterwards, the men hurl themselves into the cold water of the Owase Bay in order to cleanse themselves. It is a very lively and unique festival, and it is supposed to pray for a good harvest.
