They say Empress Jingu prayed this land would find eternal peace, and in the 6th century the area was named Mozu, meaning "eternity." Mozu Hachimangu Shrine was built in Empress Jingu's memory. In 1158, Mozu Hachimangu became an auxiliary shrine to Iwashimizu Hachimangu and began to attract worshipers from all walks of life; everyone from the feudal lord of Izumi and members of the imperial court, samurai, to common people. Most of the buildings were in a fires, caused either by war during the summer siege of Osaka or by repeated disasters. The shrine's autumn moon viewing festival boasts a 300-year history. The parade of floats, accompanied by cheerful shouts, makes for a lively, magnificent sight. There is also a large, 800-year-old camphor tree on the grounds that has been designated a natural monument.
