The origin of Karatoyama-shinji sumo in Hakui City, designated as an intangible cultural property, is said to be traced back to the event in which the people used to celebrate Sumo on the 25th day of the 9th month, the anniversary of Iwatsukuwake no mikoto's death, every year to recall him and his good governance.
