Yosuke\'s family has a strange tradition - once every sixty years they receive an egg from a mermaid.
But as a commercial development encroach on the sleepy seaside village and Yosuke\'s father is lured away from tradition towards modern properity, and turns the egg into a touri.
In exchange for this favor, the mer-people bless his coastal town with bountiful catches of fish and calm seas.
When the egg matures his family dutifully returns it to the sea, where the whole process is then repeated.
