The cave at Udo Jingu

The shrine, or rather shrines, at Udo Jingu are inside a cave in the cliff overlooking the sea. The main kami is named Ugayafukieazu, though there are variations on the name and its spellings. In the mythology, he was the father of Jimmu, the first emperor.

In the legend his mother, Toyotamahime constructed a birth hut here made out of cormorant feathers. and told her husband Hoori, sometimes known as Hohodemi or Yamasachihiko, not to look while she was giving birth as she would revert to her non-human form as the daughter of Ryujin, the undersea Dragon King.

He peeked and then freaked out at her appearance and she was so ashamed that she left the child and ran away. For some reason the shrine is considered lucky for newly-weds.

Deeper in the cave , behind the main shrine, are numerous smaller shrines that enshrine Yamasachihiko, Toyotamahime, Ninigi, Amaterasu, Jimmu, etc.

In the cave roof are rocks shaped like breasts. It is said that as a baby Jimmu suckled from them. The shrine sells a kind of candy made from the water that drips down the rocks.

Dejima Shrine

Located right next to Manganji on the shore of Lake Shinji, the shrine is quite unusual in that it does not have a torii. It was in all probability part of the the same temple-shrine complex before the Meiji Period. The name of the kami enshrined here also suggest a Buddhist past: Nanagami Daimyojin..... which is in fact seven related kami.

The first is Ninigi, the grandson of Amaterasu sent down from the High Plain of Heaven to rule Japan. Next come Hoori, youngest son of Ninigi but more commonly known as Hikohohodemi or Yamasachihiko. Also enshrined here is Hoori's wife Toyotamahime, daughter of the sea god Ryujin,

After returning from some years living in a palace under the sea Toyotama gave birth to a son Ugayafukiaezu in a famous legend involving a birthing hut. Fukiaezu married his aunt Tamayorihime , also enshrined here, and became the father of the mythical first Emperor Jimmu.

The final two kami here are Konohanasakayuhime, now most commonly associated with Mount Fuji,  the princess who married Ninigi and gave birth to Hoori, and the final kami who I am having difficulty tracing the relationship to the others is Kushiyatama, who is connected to the Kuniyuzuri myth and is I believe connected to a ritual that still occurs not to far from here at Hinomisaki Shrine.

All the other kami are connected to the myths of southern Miyazaki in Kyushu centered around Aoshima Shrine
