Fukuji to Yumihiko: Umi wo Watatte Kita Ushikai Shounen

In the Tenpyo period, a boy named Fukuji arrives in Japan from across the sea with his village, bringing cows and a culture of using milk. He meets Yumihiko, a boy from a local Japanese village that grows rice, and they become friends. Their peaceful lives are disrupted when bandits attack their villages, forcing the two communities to work together.

Through their cooperation, Fukuji and Yumihiko learn to overcome cultural differences and build trust. The story explores how the exchange of knowledge and resources between the cow-herding newcomers and the rice-farming locals leads to mutual understanding and progress.
