In Osaka, the shrine is known affectionately as "Sumiyossan." Every year, from January 1st to 3rd, the shrine welcomes more than 2 million people for Hatsumode, the traditional first shrine visit of the year. The head shrine for Japan's approximately 2,300 Sumiyoshi shrines, Sumiyoshi Taisha is the most important shrine in the Osaka area. Praying to the gods here is believed to ensure maritime safety, as well as good luck in farming, waka poetry, martial arts, and sumo wrestling, and to ward off disasters of all kinds. Built more than 1,800 years ago, the buildings are arranged to resemble a fleet of ships headed out to sea. The shrine was built in an architectural style known as Sumiyoshi-zukuri, the oldest style used in shrine construction, and is registered as a national treasure. Sumiyoshi Taisha has more than 30 auxiliary shrines, as well as a number of festivals and rituals, including Sumiyoshi Matsuri. The grounds of the shrine are carefully preserved as a national treasure and important cultural property for their architectural and cultural value.
