Arashima Hachimangu is located right on Route 9. Hachiman is usually a trio of kami, Homuda Wake, the name of Emperor Ojin, is usually the primary, and the other two being taken from his mother, Jingu, his father, Chuai, or his wife, Himegami. Unusually this one lists Homuda Wake, Jingu, and Takeuchi Sukune, who was Jingu's minister.
It is a direct branch of the Usa Hachimangu. Almost two thirds of Hachimangu nationwide are branches of Iwashimizu. Like all the other shrine in this area there was a Zuijinmon which also had a pair of nice wooden komainu.
Again, like all the other shrines in the area there was an altar to Kojin, the most common kami in the region that hardly gets a mention in any sources on Shinto as it is neither national nor imperial. Represented as a rope snake, in my neighboring area the name is different, but it is just as prevalent and important.
There are several outcroppings of smooth, rounded rock in the grounds. The smaller one has a hokora to Sumiyoshi in a small hole carved into it.
The larger one has steps carved into it that leads up to an Inari Shrine.
