As winter arrives, the Zao mountain range in Yamagata Prefecture transforms into a wonderland of “Snow Monsters,” colossal natural ice formations that captivate visitors from around the world. These awe-inspiring creations, formed by a unique combination of climate and geography, attract numerous tourists every year.
Zao’s Snow Monsters are the result of seasonal winds carrying vast amounts of moisture from the Sea of Japan. When these winds collide with the Zao mountain range, they generate snow clouds filled with supercooled water droplets. These droplets freeze onto the branches of Aomori fir trees, gradually forming layers of ice and snow. Through this repeated process, the trees grow into massive, surreal shapes, taking on the form of Snow Monsters.
The formation of Snow Monsters is highly sensitive to weather conditions. If the required climate conditions are not met, the growth of these ice formations can be hindered. This unpredictability makes each year’s Snow Monsters unique, adding to their charm.
Growth Process of Snow Monsters
1. Ice Formation (Around November)

Supercooled water droplets attach to the branches of Aomori fir trees, beginning to freeze gradually. At this stage, the Snow Monsters do not yet have their distinctive shapes.
During this phase, strong winds and snowfall continue to impact the ice formation. Trees located at higher altitudes experience a faster rate of ice accumulation due to lower temperatures.
2. Snow Accumulation

As snow continues to fall, it blankets the frozen trees, gradually covering their branches and trunks.
The wind-blown snow contributes to the irregular and unique shapes characteristic of Snow Monsters. When the snow is moist, the formations tend to appear smoother and thicker, while dry snow preserves the fine details of the tree branches.
3. Growth (January to February)

The repeated cycles of ice formation and snow accumulation allow the Snow Monsters to take on their distinctive shapes, resembling giant, wind-sculpted figures.
Their shapes vary depending on wind direction and snowfall. Strong winds can create snow drifts, causing the formations to stretch in specific directions.
4. Peak Season (February)

This is when the Snow Monsters reach their maximum size and take on their most spectacular appearance. The landscape becomes an overwhelming display of snow and ice.
On clear days, the glistening white scenery stretches far and wide. The view from the ropeway is breathtaking, but standing among the towering Snow Monsters is an experience like no other.
5. Decline (Around March)

With the arrival of spring, rising temperatures begin to melt the ice formations, gradually eroding their shapes until they disappear.
During this period, parts of the Snow Monsters may collapse, revealing the trees beneath. Observing their gradual transformation is another fascinating aspect of their natural cycle.
The Charm of Snow Monsters
1. Colossal and Unique Shapes

Snow Monsters take on otherworldly forms, appearing almost as if they were living creatures. Their immense size and intricate designs make them a breathtaking natural spectacle.
Since no two Snow Monsters are alike, each visit offers a new and unique landscape influenced by changing weather patterns and wind directions.
2. Contrast with Sunlight

On sunny days, the Snow Monsters glisten under the sunlight, creating an ethereal winter wonderland. The contrast between the bright blue sky and the icy formations makes for a picturesque scene.
During sunrise and sunset, the Snow Monsters take on hues of orange and pink, offering an even more mesmerizing view.
3. Illuminations

At night, the Snow Monsters are illuminated with colorful lights, creating a mystical atmosphere distinct from their daytime appearance. The softly glowing ice formations resemble something out of a fantasy world.
Different colors enhance the translucent nature of the ice, casting a dreamlike ambiance over the entire landscape.
Best Spots to View the Snow Monsters
