Jigokudani Yaenkoen was established in a place called Jigokudani (Hell Valley), which is surrounded by steep cliffs and fuming springs.

Since its opening in 1964, the Jigokudani Wild Monkey Park has become a popular tourist attraction for locals and visitors alike, as a place to observe the ecology of Japanese monkeys up close.

In 1970, LIFE magazine published a picture of monkeys soaking in a hot spring, and the park became popular worldwide.

The charm of Jigokudani Yaen-koen

Here, you can enjoy the true nature of Japanese macaques, who live freely in the wilderness, soaking in hot springs, not the ones in zoos.

The monkeys soaking in the hot springs to ward off the harsh cold of Jigokudani will make you feel charming with their human-like expressions.

Normally, the wild monkeys would not stand still long enough to be observed, but by feeding them in the facility, the monkeys are able to enjoy the hot spring.
However, by feeding the monkeys in the facility, we are able to observe the monkeys as they seek the food.

It is recommended to use binoculars when observing the monkeys, and if you check their faces, arms, legs, etc. in detail, you will be able to clearly understand the differences between them and other animals.
