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

The Shimokita Peninsulamarks the northernmost limit of Honshu's habitat, and also the northernmost limit for many animals found on Honshu. These include the Asiatic black bear, Japanese serow, Japanese deer, wild boar, Japanese red fox, and Japanese macaque. Conversely, animals found in Hokkaido, such as the brown bear, Hokkaido deer, red fox, and Hokkaido squirrel, do not inhabit areas south of the Shimokita Peninsula.

This is because the Tsugaru Strait is approximately 450m deep at its deepest point and about 130m even at its shallowest point, and because Honshu and Hokkaido have never been connected by land, and because the ocean currents are strong, it is believed that the animals inhabiting Honshu and Hokkaido are completely different. Thomas Brakeston, a British zoologist who was staying in Japan, noticed this difference and presented it to the scientific community in 1883 (Meiji 16). For this reason, the dividing line of animal species inhabited by the Tsugaru Straitthe Brakeston Lineis called


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

The Shimokita Peninsula is the northernmost limit for some animals, and while monkeys and wild boars are not found in Hokkaido, the Japanese macaques that live on the Shimokita Peninsulanot only the northernmost primates in Japan, but also the northernmost primates in the world outside of humansare

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 world's northernmost monkey population, are now facing significant problems in their relationship with humans due to their large population. One of these problems is damage to agricultural crops. While the Japanese macaques remain important to the people of Shimokita, they have also become, in a sense, hostile animals. It may be time to reconsider how humans and macaques can coexist peacefully, including through conservation policies.
