Charms of Trekking on Sado

Sado's mountains are characterized by "flowers" and "natural cedars." We shouldn't compare them with other mountain ranges, but since you have come all this way across the sea, let us give you a taste of the mountains of Sado Island.


Colorful trekking to enjoy the sea and flowers

The traverse route from Donden Highland to Mount Kinpoku offers views of the ocean on both sides, and from spring to summer, a variety of alpine plants bloom in abundance, making it hard to believe that the mountain range is only about 1,000 meters high. Such wonders happen in the mountains of Sado.

Still increasing? The wonder of variety and volume

The volume and variety of mountain flowers is very large and continues to increase. Since there are no animals larger than a raccoon dog on the island, there is no feeding damage to wildflowers. The abundance of species is also due to Sado's climate, which has a wide range of vegetation from warm-temperate to cool-temperate, creating a microcosm of Japan's vegetation.

Even though we are 1,000 meters above sea level: the wonder of alpine flora!

TThe highest peak in the Osado Mountain Range, Mount Kinpoku, is 1,172 meters above sea level, and the traverse route is located at about 1,000 meters above sea level. There is an abundance of alpine flora that appear at altitudes of around 1,500 meters above sea level on the mainland. This mysterious phenomenon has a name, "summit effect," and is thought to be due to the harsh environment on the ridges caused by strong sea breezes, but the cause is not clearly known.

A Request to Protect the Environment

To protect and keep intact the wonders of Sado introduced above, we have three simple requests for you.

Request #1Do not leave trash.

Even if you don't do it on purpose, you may accidentally drop something from your bag or pants pocket. Please be especially careful when putting things in and out of your pockets. Never try to hide trash in the grass.

Request #2Stay on the trail!

Mountains are full of fascinating flowers and beautiful scenery. You may be tempted to take one more step to get closer. At that moment, make sure to take your eyes off the screen of your smartphone or camera and look at your feet. Are you stepping on a flower? With just a little bit of caution, you can protect the precious vegetation.

Request #3Collecting plants is prohibited.

The abundance of flowers on Sado Island is protected not only by the lack of foreign enemies, but also by the manners of climbers. No matter how beautiful they are, they cannot be taken as souvenirs. Flowers should be enjoyed there along with the environment in which they grow, and only photographs should be taken home.


A pristine forest of natural cedars full of character

Natural cedars, which have been wonderfully shaped by the harsh nature of the Osado Mountain Range, are more than 300 years old. How did these so-called "strange cedars" come to exist? We will introduce them with the history of Sado.

Flexible and twisting? The Mystery of Formation

Beautiful and mysterious shapes are natural art. The climate of the Sado Mountain Range has a great influence on these shapes. In winter, 40-50 m/s winds blow and there is snowfall. It weighs about 1 ton and bends the branches, but in spring the snow melts and the cedars grow upward. The formations created by this repetition are proof that the trees are thriving in this harsh natural environment.


The advantage of being different? The Mystery of why the strange trees remained intact

The natural forests on Sado Island were under control of the Shogunate in the Edo period (1603-1868), followed by national control from the Meiji period (1868-1912). They were later purchased by Niigata Prefecture. The natural cedars were cut down and sold to cover the purchase cost, but at that time, straight, good-quality trees were favored and the strange trees remained, only to attract attention today for their beautiful formations.
