Alongside Asakusa, one of Japan's three biggest Kannon.

Osu Kannon is where Buddhist asceticism is practiced in the worship of the bodhisattva Avalokiteśvara or "kannon" in Japanese. It is one of three temples dedicated to the kannon in Japan. Owing to the presence of the Kannon, Osu has historically been a flourishing Monzen-cho. When military commander, Ieyasu Tokugawa of one of Three Heroes of the Waring-States Period developed the town of Nagoya he relocated the temple from its previous location to avoid repeated flooding. Many yearly events are held here including a Setsubun festival.
