Natural Monument "Monkeys of the Shimokita Peninsula and their northernmost habitat"

The Shimokita Peninsula is the northernmost point of Honshu, but it is also the northernmost point for animals that live on Honshu. Animals that live there include the Asiatic black bear, Japanese serow, Japanese deer, wild boar, Japanese fox, and Japanese macaque. However, animals that live in Hokkaido, such as the brown bear, Ezo deer, Ezo red fox, and Hokkaido squirrel, do not live south of the Shimokita Peninsula.

This is because the Tsugaru Strait is about 450m deep at its deepest point and about 130m shallowest, Honshu and Hokkaido have never been connected by land, and the ocean currents are fast, so it is thought that the animals that live on Honshu and Hokkaido are completely different. This difference was noticed by Thomas Brakeston, a British zoologist who was staying in Japan, and was presented at an academic conference in 1883 (Meiji 16). For this reason, the dividing line between the animal inhabitants caused by the Tsugaru Strait is called the Brakeston Line


Shimokita Peninsula: The world's northernmost Japanese macaques expand their habitat

The Shimokita Peninsula is the northernmost limit for this animal, and monkeys, wild boars, and other animals are not found in Hokkaido, but the Japanese macaques that live on the Shimokita Peninsula are the "northernmost primates" not only in Japan but also in the world, other than humans

The Japanese macaques of the Shimokita Peninsula became known nationwide in the 1960s when they were spotted on the coast of the Wakinosawa area in the southwest

In 1970, the capture of monkeys was banned throughout the Shimokita Peninsula, where there were four groups at the time, and three of the groups living in the Wakinosawa area were designated as national natural monuments in order to protect their wild state

A survey conducted in the 1970s confirmed six groups of approximately 230 individuals, but their habitat was limited to the west coast area, including Wakinosawa

However, a survey conducted in March 2000 showed that the number had increased to 20 groups of approximately 800 individuals, and they could be spotted throughout the Shimokita Peninsula. Now, some 20 years later, the number has increased to an astonishing 2,500 individuals

Japanese macaques are originally animals that live in the south, but they have gradually adapted to Japan's climate and are now able to live in the extremely cold Shimokita Peninsula. Of course, conservation policies are involved in the rapid proliferation of Japanese macaques on the Shimokita Peninsula, but it is certain that a major factor is that global warming has made the average temperature higher, making it more livable

the northernmost monkeys in the world , but their rapid increase has led to serious problems in their interactions with humans. One of these is damage to crops. While Japanese macaques remain important to the people of Shimokita, they have also become hostile in some ways. Perhaps it is time to rethink how we can coexist peacefully with humans, including through conservation policies.
