It remains a true hidden gem that captures the harmonious blend of nature, culture, and relaxation.
2. The History and Culture Behind Zao’s Hot Springs
Zao Onsen has a rich and ancient history that stretches back nearly two millennia. According to historical records, the hot springs were discovered around the year 110 CE by a traveling priest who noticed the therapeutic qualities of the steaming, mineral-rich waters. Over time, Zao Onsen became a revered healing site, attracting samurai, monks, and local villagers who sought relief from physical ailments and spiritual cleansing in its naturally acidic waters.
The onsen’s strong sulfur content gives the water its distinctive milky appearance and pungent aroma. While this may seem unusual to first-time visitors, locals believe that “the stronger the smell, the stronger the healing.” This cultural view is deeply rooted in Japanese traditions that emphasize the health benefits of natural springs, especially those that can soothe joint pain, promote blood circulation, and treat various skin conditions.
Over the centuries, Zao Onsen grew from a small collection of communal baths into a well-developed hot spring town. Today, the town still retains its traditional charm, with cobblestone streets, wooden inns, and yukata-clad visitors walking to and from bathhouses. Several public bathhouses such as Kamiyu and Shimoyu are still in operation, offering affordable access to the waters for around ¥200–¥500 ($1.30–$3.30 USD), preserving the onsen culture for both locals and tourists.
Cultural traditions are deeply interwoven into daily life in Zao. Seasonal festivals such as the “Zao Juhyo Festival” celebrate the region’s snowy wonders while also honoring the onsen’s historical role in community wellness. Local artisans craft souvenirs and health products using sulfur and minerals from the springs, blending traditional practices with modern creativity.
Furthermore, Zao Onsen’s connection to spirituality cannot be overlooked. In the past, many bathers followed ritualistic bathing procedures believed to purify not just the body but also the soul. Temples near the town, like Zao Daigongen Shrine, reinforce this spiritual link, serving as a reminder of the onsen’s sacred origins and its enduring role in the local identity.
In essence, Zao Onsen is not just a place to bathe—it is a living symbol of cultural heritage, historical depth, and spiritual rejuvenation. Its continued popularity is a testament to the powerful bond between nature, health, and Japanese tradition.
3. Winter Wonderland: Exploring Zao’s Snow-Covered Scenery
Zao Onsen transforms into a breathtaking winter wonderland from December to early March, drawing visitors with its magical landscapes and serene atmosphere. The entire region is blanketed in thick layers of snow, creating postcard-perfect scenes of snow-covered rooftops, frozen trees, and steaming hot springs surrounded by white tranquility. Among the most iconic sights in Zao is the phenomenon known as the “Snow Monsters” or juhyo, which are trees completely encrusted with snow and ice due to harsh Siberian winds.
These Snow Monsters, found near the summit of Mount Zao, are a rare natural spectacle unique to only a few places in the world. Their eerie, towering shapes are the result of a meteorological phenomenon where supercooled water droplets freeze instantly onto trees. The best way to experience them is by taking the Zao Ropeway, which lifts visitors above the forest to an elevation where the juhyo fields stretch endlessly across the mountain slopes. At night, the creatures are illuminated in a spectacular light-up event, offering a surreal and unforgettable view.
Photography enthusiasts and nature lovers are drawn to the area to capture the beauty of Zao’s frosted wilderness. Snowshoeing and guided walking tours are available for those who want to explore the silent forests on foot, while others may choose to enjoy the view from cozy cafés or open-air baths overlooking the snowy landscape.
The contrast between the cold, white exterior and the warm, mineral-rich waters of Zao’s outdoor hot springs creates a uniquely satisfying experience. Visitors often enjoy soaking in traditional rotenburo baths while snowflakes fall gently around them—a sensory delight that blends natural beauty with complete relaxation.
For travelers on a budget, winter in Zao can be surprisingly accessible. Round-trip transportation from Yamagata Station and ropeway tickets typically cost around ¥3,000–¥4,500 ($20–$30 USD), and even more affordable lodging can be found during non-peak weekdays. However, it’s best to book in advance, especially during holiday periods or festival weekends.
Exploring Zao in winter is more than just sightseeing; it’s an immersive experience that awakens the senses and leaves lasting memories. Whether marveling at the Snow Monsters, soaking in a snowy hot spring, or simply walking through the peaceful streets of the onsen town, Zao offers a glimpse into the serene power of nature in its purest winter form.

The longest course stretches over 10 kilometers, offering panoramic views of the surrounding mountains.

For those who prefer a slower pace, snowshoe trekking is a great way to explore the quieter parts of Zao’s winter forest.

Another popular activity is taking the Zao Ropeway to view the juhyo (Snow Monsters), especially during the evening illumination events which run from late January through February.
Off the slopes, Zao offers a variety of cultural and leisure experiences.

The baths are available at most ryokan inns, or visitors can enjoy public options for as little as ¥500 ($3.30 USD).
Zao’s winter food scene is another highlight. Local specialties such as nabe (hot pot), gyutan (grilled beef tongue), and imoni (taro and meat stew) provide hearty warmth after a cold day. Many ryokan include traditional multi-course dinners in their accommodation packages, usually ranging between ¥12,000–¥25,000 ($80–$165 USD) per night.
In addition, seasonal festivals like the Zao Juhyo Festival celebrate the winter spirit with fireworks, music, and local crafts. These events offer a great way to engage with the local community and learn more about Yamagata’s winter traditions.

5. Travel Tips for Visiting Zao Onsen in Winter
Visiting Zao Onsen in the winter is a magical experience, but proper preparation can make your trip smoother, safer, and more enjoyable. With heavy snowfall, chilly temperatures, and high-altitude conditions, it’s important to plan carefully to fully appreciate everything this winter wonderland has to offer.
First and foremost, dress appropriately for cold and snowy weather. Temperatures in Zao can drop below -10°C (14°F), especially in the early morning and evening. Layering is key—thermal underwear, a down jacket, waterproof pants, and snow boots are essential. Don’t forget gloves, a hat, and a scarf, especially if you plan to explore the Snow Monsters or ride the ropeway.
For transportation, the most convenient route is to take the Yamagata Shinkansen from Tokyo to Yamagata Station, which takes about 2.5 hours. From there, shuttle buses run regularly to Zao Onsen, with a one-way ticket costing around ¥1,000 ($6.60 USD). Roads in the area can be icy, so if you’re renting a car, ensure it’s equipped with snow tires or chains. Parking in Zao Onsen is available but limited during peak times.
Accommodations fill up quickly during the snow season, especially on weekends and around national holidays, so it’s wise to book at least a month in advance. Many traditional inns (ryokan) offer plans that include breakfast and dinner, typically priced between ¥12,000 and ¥25,000 ($80–$165 USD) per person per night. Staying at a ryokan is not only comfortable but also provides the full Japanese onsen experience.
Bring cash, as many smaller establishments—including some bathhouses and restaurants—do not accept credit cards. While there are ATMs in Zao, they may not support all international cards, so withdrawing money at a convenience store or bank in Yamagata City beforehand is recommended.
It’s also helpful to learn a few basic Japanese phrases or have a translation app handy. While some staff at hotels and rental shops speak English, most signage and menus are in Japanese. Locals are very friendly and eager to help, but a little language support goes a long way.
Lastly, check the weather and ropeway schedules before heading out for snow-related activities. Strong winds and snowstorms may cause temporary closures or delays. Many hotels provide updates or can assist you in planning your day accordingly.
With the right preparation, a winter trip to Zao Onsen can be an unforgettable adventure filled with scenic beauty, warm hospitality, and traditional Japanese charm. Whether you’re soaking in an outdoor bath or photographing the majestic Snow Monsters, Zao in winter offers memories that will last a lifetime.
