A white lion and a group of animals are Japanese cartoons. What's its name?

The animation "White Lion" is the representative work of Japanese cartoonist Osamu Tezuka, the forest emperor.

The white lion you are talking about is Panga or Leo, the king of the forest-Panga died at gunpoint to save his wife who was taken away by human beings, and soon his son Leo was born. Leo, who was brought up by human beings, inherited his father's heroic character, and finally returned to his hometown after hardships and became a real forest emperor.

The American animated film The Lion King was also inspired by it.
