Jigokudani Monkey Park in Nagano Prefecture is one of Japan’s most unique destinations and continues to captivate travelers from around the world. The park is famous for its troop of Japanese macaques, often called snow monkeys, that are frequently seen relaxing in natural hot springs—especially during the snowy winter months. However, Jigokudani’s appeal isn’t limited to winter alone. Throughout the year, visitors can enjoy ever-changing seasonal scenery while observing different behaviors of the monkeys. This is why many travelers wonder: when is actually the best time to visit Jigokudani Monkey Park?
Winter (December–March)
Winter is the most popular time to visit Jigokudani Monkey Park. As heavy snow blankets the area, the sight of snow monkeys soaking in steaming hot springs creates the park’s iconic and dramatic scenery. From December through February, monkeys are almost guaranteed to gather around the onsen daily, giving visitors a high chance of seeing them up close. Temperatures can drop to -10°C or even -15°C, so warm clothing is essential, including thick jackets, scarves, gloves, and non-slip footwear, as the walking paths can be icy and snow-covered. Despite the challenging conditions, winter offers the most authentic experience, making it worth the journey for travelers hoping to witness this classic Japanese scene.
Spring (April–May)
As the snow begins to melt and greenery slowly returns, Jigokudani Monkey Park transforms into a fresh and welcoming destination. Spring also coincides with cherry blossom season in the Nagano area, allowing visitors to enjoy soft floral backdrops alongside the monkeys. Another highlight is the birth of baby monkeys in May, often seen playfully clinging to their mothers. Compared to winter, the atmosphere is calmer, with fewer visitors. The weather can still be unpredictable, sometimes cool or rainy, so bringing a light jacket and a compact umbrella is recommended. For those who enjoy peaceful surroundings and witnessing new life in nature, spring is an excellent choice.
Summer (June–August)
Many people assume summer is not an ideal time to visit Jigokudani Monkey Park, but it can actually be quite rewarding. During this season, the valley becomes lush and vibrant, creating a refreshing natural setting. Temperatures in the mountains are cooler than in major cities like Tokyo, making it a pleasant escape from urban heat. While monkeys rarely soak in the hot springs during summer, they can still be seen roaming freely, playing, and foraging around the park. Since summer overlaps with Japan’s rainy season—especially in June—visitors should prepare rain gear such as a raincoat or folding umbrella. With fewer tourists overall, summer offers a quieter and more relaxed experience.
Autumn (September–November)
Autumn brings a stunning burst of color to Jigokudani Monkey Park. The surrounding forests turn shades of red, orange, and yellow, creating a beautiful backdrop as the monkeys move through the landscape. During this time, monkeys tend to be more active as mating season begins and forest fruits and nuts are plentiful. The valley’s temperatures are also more comfortable than in summer, making the walk to the park more enjoyable. However, because natural food sources are abundant, monkeys may not immediately gather at the hot springs early in the day. The best time to visit is usually between 11:00 a.m. and 3:00 p.m., when sightings are more likely. Autumn is perfect for travelers who love colorful scenery without the crowds of winter.
Each season at Jigokudani Monkey Park offers its own charm—from snow monkeys bathing amid falling snow in winter, to newborn monkeys in spring, peaceful greenery in summer, and vibrant autumn foliage. Ultimately, the best time to visit depends on the kind of experience you want to have.
