Zao Juhyo Festival
蔵王樹氷まつり
The Zao Juhyo Festival showcases Snow Monsters, ethereal ice and snow formations that coat trees in the Zao Mountains, illuminated after dark to create a surreal winter landscape.

The Zao Juhyo Festival in Yamagata Prefecture, Japan, offers visitors an unforgettable winter adventure featuring the world-famous "Juhyo" or Snow Monsters. Located in the stunning Zao Mountain Range, this extraordinary winter festival showcases nature's most spectacular ice formations that transform ordinary trees into otherworldly sculptures.
Snow Monsters are unique ice and snow formations created when heavy snowfall combines with freezing winds in the Zao Mountains. These natural phenomena cover trees completely, creating eerie yet breathtaking silhouettes that have become synonymous with Yamagata winter tourism. The grotesque yet beautiful shapes make Zao's Snow Monsters a must-see attraction for winter travelers to Japan.
The Zao Juhyo Festival runs from late January through early March, when Snow Monsters reach their peak formation. This timing coincides with optimal skiing conditions at Zao Onsen ski resort, making it perfect for combining winter sports with sightseeing.
The festival's crown jewel is the colourful illumination of Snow Monsters after sunset. These spectacular light displays transform the winter landscape into a surreal, magical wonderland. The illuminated Snow Monsters create perfect photo opportunities and unforgettable memories for visitors to Yamagata Prefecture.
Visitors can access the Snow Monsters via the Zao Ropeway from Zao Onsen ski resort. The ropeway provides stunning panoramic views of the illuminated formations and the surrounding Zao Mountain Range. Fireworks displays during special festival dates add extra magic to the winter spectacle.
Beyond the famous Snow Monsters, the Zao Juhyo Festival offers:
Zao Onsen skiing on pristine powder snow
Relaxing hot springs (onsen) experiences
Traditional Yamagata local cuisine and winter delicacies
Winter hiking and snow sports activities
