Zao Snow Monsters
Are you ready to witness the magic of Zao’s famous snow monsters?
Before we delve into the details of these mysterious creatures, let’s take a step back and discover the history behind the frost-covered trees of Zao.

Zao is a volcanic mountain range located in the Tohoku region of Japan, and it is known for its beautiful scenery, natural hot springs, and world-renowned ski resorts.
The area is particularly famous for its “snow monsters,” which are trees that are covered in frost and snow during the winter months.
Legend has it that the snow monsters were once thought to be the work of demons, but the truth is much more fascinating.
In fact, the snow monsters are a result of the harsh winter conditions in the Zao mountain range. The freezing temperatures and heavy snowfall cause the trees to become completely covered in ice, creating a stunning and otherworldly sight.
To witness the snow monsters in all their glory, it’s best to visit Zao during the winter months, between December and February. The ideal time of day to see the snow monsters is in the morning, as the sunlight enhances the colors and textures of the frost and snow.
There are several vantage points throughout the Zao area where visitors can observe this phenomenon.
Each location provides a unique perspective on the snow monsters, and we will explore them in detail later in this post.
Now that you have a better understanding of the history and beauty behind Zao’s snow monsters, let’s continue our journey and discover what else this stunning destination has to offer.
Frost-Covered Trees of Zao
If you think the snow monsters are the only thing that makes Zao a winter wonderland, wait until you see the frost-covered trees.
These trees, also known as “snow monsters’ cousins,” are unique formations that are just as mesmerizing as the snow monsters.
Juhyo

The frost-covered trees of Zao are created through a natural phenomenon known as “Juhyo” in Japanese, which translates to “frost-covered trees.”
Juhyo is formed when the damp wind from the Sea of Japan meets the cold air of the mountains, causing the moisture to freeze onto the trees, forming various shapes and sizes of ice.
The best time to see the frost-covered trees is from late December to mid-February when the temperature drops below freezing, and the humidity is high. The trees are illuminated at night, adding a magical touch to the already enchanting scenery.
Additional Opportunities
Aside from marveling at the frost-covered trees, there are plenty of other activities to do in the area. Skiing is one of the most popular winter sports in Zao, and the area has a variety of ski runs for skiers of all levels.
After a long day of skiing, why not relax in one of the many hot springs around the area, allowing you to take in the scenery while you soak in warm waters?
If you’re an avid photographer looking to capture the perfect photo of the frost-covered trees, consider visiting early in the morning when there are fewer crowds, and the lighting is optimal. Also, bring a tripod and dress warmly, as you may be waiting for a while to get the perfect shot.
The frost-covered trees of Zao are just as remarkable as the snow monsters, and they are a must-see for anyone visiting the area during winter.
Whether you’re into skiing or soaking in hot springs, you’ll find plenty of things to do while admiring the winter scenery.
