In the northwest corner of Shinjuku Central Park is Juniso Kumano Jinja. This Kumano shrine originated during the 14th century and is one of 300 in Japan honoring the Kumano mountains: Hongū, Shingū and Nachi. Among its serene compound of humble wooden buildings is this hall of worship called haiden. It is believed Juniso Kumano Jinja is the guardian of Shinjuku.
