Sumiyoshi-taisha, also known as Sumiyoshi Grand Shrine, is a Shinto shrine in Sumiyoshi-ku, Osaka, Osaka Prefecture, Japan. It is the main shrine of all the Sumiyoshi shrines in Japan. However, the oldest shrine that enshrines the Sumiyoshi sanjin, the three Sumiyoshi kami, is the Sumiyoshi Shrine in Hakata.
It is called Sumiyoshi-san or Sumiyossan by the locals, and is famous for the large crowds that come to the shrine on New Year's Day for hatsumōde.
Sumiyoshi taisha enshrines the Sumiyoshi sanjin (Sokotsutsu no Ono-mikoto, Nakatsutsu no Ono-mikoto, and Uwatsutsu no Ono-mikoto) (collectively known as the "Sumiyoshi Ōkami") and Okinagatarashi-hime no Mikoto (Empress Jingū).
It gives its name to a style of shrine architecture known as Sumiyoshi-zukuri.
The shrine became the object of Imperial patronage during the early Heian period. In 965, Emperor Murakami ordered that Imperial messengers were sent to report important events to the guardian kami of Japan. These heihaku were initially presented to 16 shrines including Sumiyoshi.
Sumiyoshi was designated as the chief Shinto shrine (ichinomiya) for the former Settsu Province.
From 1871 through 1946, Sumiyoshi taisha was officially designated one of the Kanpei-taisha, meaning that it stood in the first rank of government supported shrines.
Sumiyoshi taisha was founded by Tamomi no Sukune in the 11th year of Empress Jingū's reign (year 211). A member of a powerful family in the area, he was given the clan name of Owari by the empress when she visited the coast of the Gokishichidō (Modern Shichidou in Sakai, Osaka). At the same time, she told him to enshrine the Sumiyoshi sanjin, as she had been told to do so by an oracle from Amaterasu and three Sumiyoshi kami. Later, the Empress herself was also enshrined at Sumiyoshi. The Tsumori clan, whose members have succeeded the position of head priest of Sumiyoshi taisha since the reign of Emperor Ōjin, are the descendants of Tamomi no Sukune's son, Tsumori no Toyoada (or Tsumori no Toyonogodan).
