A coloring book with a story, illustrated by Masayuki Yogi, an artist born in Naha, Okinawa. The theme is the sea, which is home to many living things. The sea creatures are covered in patterns that have been handed down in Japan and Okinawa since long ago, and you color them as you read through the story.
Some pages have a sea background that is already printed in color, and some pages have die-cut holes. Once the coloring is finished, the book can also be read as a picture book. It is published by Kokuyo.
Translated from the Japanese original.
