Older brother was Umisachi-hiko and younger brother was Yamasachi-hiko.

Umisachi-hiko was good at fishing and cherished his fishing pole, while Yamasachi-hiko was good at hunting and cherished his arrow.

One day they exchanged their tresures at the request of Yamasachi-hiko.

However, Yamasachi-hiko lost the fish hook.

Yamasachi-hiko aplogized Umisachi-hiko for the loss of fish hook, but Umisachi-hiko got very angry and didn’t allowe Yamasachi-hiko.

Yamasachi-hiko explored to the sea world in search for the fish hook.



It is said that there had been the Palace of Sea Dragon in Ibusuki City, Kagoshima Prefecture.

A princess of the castle used to drew water at the old well “Tamanoi” which is located at Kaimon District of Ibusuki City.
