From the perspectives of an adventurer, a diver (fisherman), and a free diver, they describe their thoughts on the ocean of Kohama Island in the Yaeyama Islands.
Protected and nurtured by the sea, their thoughts are those of the people living in the Yaeyama Islands.
What they feel from the sea, which is their blood and flesh, is different from what they see through TV monitors.
I want you to visit and feel what this ocean is.
How should we face this ocean?

However, in spite of their thoughts, the sea stands quietly with many living creatures far beyond human beings.
