Climbing out of the Fukuoka Plain on a small road that leads over to the next pilgrimage temple I spied a torii and went to investigate and found Naka Homan Shrine.
Less than a kilometer away is Homan Shrine, and I'm guessing this was built as a branch of it in 1675.
The three kami listed are Tamayorihime, Okinagatarashihime, and Homuda Wake. The latter two are more commonly known as Empress Jingu and Emperor Ojin, but this is not called a Hachimangu. According to the myth Jingu gave birth to Ojin not too far from here in Umi.
Exactly who Tamayorihime is remains a mystery. There are several famous kami with the same name as it really just means a woman who lies down with a kami and bears his child.
