The museum sits at the foot of Kotohira-gu, which is a shrine that has been known since ancient times for housing the protective deity of the sea. Introducing a wide range of topics about the sea, from the history of humans and the ocean, the deep abyss, and the functions of seacrafts. A facility able to be enjoyed by adults and children alike, with a radio-controlled ship corner, observatory modeled after a ship's wheelhouse, and more. Have a great time learning about the wonders of the ocean and its vessels by seeing and touching.
