■山佐知毘古 / Yamasachihiko
He is a god of agriculture and hunting, one of the sons of Ninigi and Sakuyahime. His brother is Umisachi.

One day, Yamasachi wanted to try fishing and borrowed a hook from his brother Umisachi.
Yamasachi couldn't even catch fish and lost hook. Since then, his brother has continued to blame Yamasachi.
Yamasachi later marries Wadatsumi's daughter. Wadatsumi was a powerful sea god, so it was easy to find a hook. At the recommendation of Watatsumi, Yamasachi cursed the hook and returned it to his brother.

■Meaning
“山/yama” means ”mountain” and “field”.
“佐知/sachi” means “a hunting equipment”.

■Concept
Mt. Fuji in Japan is drawn in the background.
He works with Wadatsumi to beat his brother. That's why I portrayed him as a mischievous boy.
The pattern on the face is the same for the brothers.
