Every winter, something extraordinary happens on the upper slopes of Mount Zao in Yamagata Prefecture. Fir trees, battered by freezing Siberian winds and laden with accumulated ice and snow, transform into towering creatures known as juhyo — literally “ice trees”, but commonly called the snow monsters of Japan. If you’ve ever scrolled through travel photos and thought, “That can’t be real,” — it is. And this guide will show you exactly how to see them.
Standing before a field of snow monsters at dawn, with mist swirling around their ghostly forms and the roar of skiers echoing somewhere below, is one of the most surreal and unforgettable experiences Japan has to offer. Whether you’re a photographer chasing that perfect shot, a ski enthusiast looking for a unique resort experience, or a Japan lover ticking off a genuine bucket-list moment, the Zao Snow Monsters deserve a prominent spot on your itinerary.
What Are the Zao Snow Monsters?
The Science Behind Juhyo
Juhyo form through a combination of two meteorological conditions that occur almost uniquely on Mount Zao. First, the mountain sits in the path of cold air masses flowing in from Siberia across the Sea of Japan. This air carries enormous amounts of supercooled water droplets. Second, Mount Zao’s high elevation — the summit sits at 1,841 metres — ensures that temperatures stay well below freezing from late November through March, sometimes dipping as low as minus 20°C.
When the supercooled droplets contact the Aomori fir trees (Abies mariesii) that cover the upper slopes, they freeze instantly on contact, building up in layers over days and weeks. The result is trees encased in fantastical shapes — some resembling crouching bears, others like robed monks, others like alien creatures you’d expect in a Studio Ghibli film. Individual juhyo can reach heights of 6–8 metres and weigh hundreds of kilograms. The phenomenon is at its most impressive between late January and mid-February.
Why Zao’s Snow Monsters are Unique in Japan
While rime ice (juhyo) occurs in other high-altitude locations in Japan, including parts of Nagano and Hokkaido, the scale and visual density of the snow monsters at Zao is unmatched anywhere else in the country. The Aomori fir trees grow in dense stands on Zao’s slopes, creating vast fields of monster shapes that stretch across the mountain for hundreds of metres. This combination of tree species, elevation, and prevailing weather creates conditions no other location in Japan can fully replicate.

Top Recommendations: How to Experience the Snow Monsters

1. Ride the Zao Ropeway to the Monster Zone
The most accessible way to see the snow monsters is via the Zao Ropeway system, which consists of two connected gondola lifts running from Zao Onsen village (elevation 880m) to Jizo Sancho Station near the summit (elevation 1,661m). The Sanrokusen (lower) gondola runs from the base to Juhyo Kogen Station (elevation 1,387m), where you already encounter the beginning of the monster zone. The upper Sancho Liner takes you further to Jizo Sancho, where the concentration of juhyo is densest. Round-trip tickets cost approximately 3,200 yen for adults and 1,700 yen for children. The ropeway runs from 8:30am to 4:30pm during peak winter season (late December through mid-March). On clear mornings, the light through the frozen trees is simply extraordinary.
2. Night Illumination Viewing
For a dramatically different experience, the Zao Ropeway runs special night illumination events on select weekends from late January through February. After dark, coloured lights are projected onto the snow monsters, transforming the mountainside into a glowing landscape of blues, greens, and purples. The contrast between the illuminated ice creatures and the dark winter sky creates some of the most striking photographs possible in Japan. Night ropeway tickets cost slightly more than daytime tickets (around 3,600 yen round trip) and events typically run from 5:30pm to 9pm. Book your round trip before heading up — demand is high during illumination periods.
3. Ski Through the Monster Zone
Zao Onsen Ski Resort is one of Japan’s largest and most varied ski areas, with 21 lifts servicing 26 different runs across 10 kilometres. The resort receives average snowfall of 7–8 metres per season, producing powder conditions that rival Hokkaido. What sets Zao apart from other Japanese ski destinations is the ability to ski directly through the snow monster zone on the upper mountain runs. The sensation of schussing through a forest of frozen giants while surrounded by fine powder is genuinely otherworldly. Day lift passes cost approximately 4,700 yen for adults and 2,700 yen for children. Ski and snowboard rentals are widely available in the village for around 3,500–5,000 yen per day including boots.
4. Snowshoe Through the Monster Fields
For non-skiers wanting a more immersive encounter, guided snowshoe tours take small groups through the monster zone at a leisurely pace, stopping for photographs at the best angles. These tours typically last 3–4 hours, cost between 5,000 and 8,000 yen per person including all equipment, and are available in English through various activity operators. The slower pace of snowshoeing versus skiing allows for better photography and a deeper appreciation of the individual monster shapes. Early morning departures (before 9am) offer the best light and fewer crowds.
5. Soak in Zao Onsen Hot Springs
After a day on the mountain, Zao Onsen village offers some of the most mineral-rich hot spring baths in Japan. The water here is strongly acidic — pH 1.2 to 1.7 — which gives it remarkable antibacterial properties and a distinctive skin-smoothing effect. The onsen water has a milky white colour from the dissolved sulfur compounds and feels noticeably thicker than ordinary water. The village has multiple public bath houses (konyoku) open to day visitors for around 500–800 yen, plus dozens of ryokan and hotels with private or semi-private baths for guests. The combination of fresh mountain air, powder skiing, and mineral onsen soaking in the same day is hard to beat anywhere in Japan.

Tips and What to Expect

Best Time to See the Snow Monsters
The juhyo season typically runs from late December through mid-March, but the monsters are at their biggest and most impressive from late January through mid-February. Before January, the trees are beginning to form their icy coats but haven’t reached their full size. After February, warming temperatures cause the monsters to start collapsing and losing their definition. The absolute peak window is roughly January 25 to February 15. Check the Zao Ropeway’s official juhyo forecast (updated daily during the season) before planning your visit, as snowfall varies year to year.
What to Wear
Dress for extreme cold. At Jizo Sancho Station (1,661m), temperatures routinely fall to minus 10 to minus 15°C, with wind chill making it feel colder. Even if you’re not skiing, wear: a waterproof outer layer (ski jacket or equivalent), thermal base layers, waterproof ski pants or insulated trousers, waterproof gloves (mittens are warmer than gloves), a hat that covers your ears, a neck gaiter, and waterproof, insulated boots. Ski goggles are useful on windy days. Camera batteries drain quickly in extreme cold — keep a spare in an inside pocket.
Getting There: Step by Step
From Tokyo: Take the JR Yamagata Shinkansen to Yamagata Station (approximately 2 hours 30 minutes, from around 11,000 yen one-way; JR Pass eligible). From Yamagata Station, take the Yamagata Kotsu bus directly to Zao Onsen bus terminal (approximately 40 minutes, 1,040 yen). Buses depart roughly every 30–60 minutes. From the bus terminal, the ropeway base station is a 5-minute walk. Alternatively, direct shuttle buses run from Sendai Station (approximately 90 minutes) during peak winter season, which is convenient if you’re coming from the Tohoku Shinkansen mainline.
Insider Tips for Photographers
The light is most dramatic within an hour of sunrise and an hour before sunset — but getting the first ropeway of the morning (8:30am departure) is your best bet for fresh, untouched snow around the monsters and minimal crowds. On overcast days, the soft light eliminates harsh shadows and creates an ethereal mood that many photographers prefer over bright sunshine. Shoot in manual mode if possible, as automatic exposure systems tend to underexpose in bright snow. Bring a polarising filter to cut glare on clear days.
Eating and Drinking at Zao Onsen
Local Food Scene
Zao Onsen village has a surprisingly vibrant food scene for its size, thanks to the steady flow of skiers and onsen visitors year-round. The local specialty to try is imoni — Yamagata’s beloved taro potato stew, slow-cooked with beef and soy sauce in a deep, savoury broth. Most restaurants in the village serve their own version alongside rice, pickled vegetables, and seasonal sashimi from mountain rivers. For breakfast, the ryokan typically provide elaborate Japanese-style spreads including grilled fish, miso soup, tamagoyaki (rolled omelette), rice, and pickles — the perfect fuel for a morning on the slopes or the ropeway.
Sake enthusiasts should look for Yamagata’s distinctive local labels: Dewazakura, Juyondai, and Gassan are among the prefecture’s finest producers, and izakaya in the village stock them alongside hearty regional dishes like Yamagata beef sukiyaki and vegetable-heavy mountain cuisine (sansai ryori). Budget around 1,500–2,500 yen for a satisfying lunch at mid-range village restaurants, or 700–1,200 yen for ramen and set meals at simpler spots near the ropeway base. Many restaurants also serve a warming cup of amazake (sweet fermented rice drink) for around 300 yen — the perfect way to warm up after an hour in the cold monster zone before your onsen soak.
Omiyage: Souvenirs to Take Home
The souvenir shops near the Zao Ropeway base sell a range of Yamagata products worth bringing home: Yamagata cherries (in season and preserved), kokeshi wooden dolls crafted in the Naruko style, Zao Onsen bath salts (which recreate the acidic mineral water experience at home), and local sake. The bath salts in particular make excellent gifts for Japan-loving friends who haven’t yet made it to Yamagata themselves.
