What Are the Misotsuchi Icicles in Chichibu?
Misotsuchi Icicles (Misotsuchi no Tsurara) are a spectacular winter sightseeing spot in Ōtaki, Chichibu City, Saitama Prefecture, along the upper Arakawa River.
Spring water flowing from the rock face freezes during the coldest part of winter, creating natural ice formations known as a work of art shaped by nature.
The best time to visit is usually from mid-January to mid-February, when the natural icicles form an ice wall about 8 m high and about 30 m wide.
Upstream from the natural icicles, there are also artificial icicles made by spraying water, and these are even larger in scale at about 50 m wide and about 25 m high.
At night, a magical illumination is held, allowing visitors to enjoy a mysterious view that feels different from the daytime scenery.
It is known as one of the Chichibu Three Great Icicles and is especially famous as the place where you can see natural icicles.

Misotsuchi Icicles Highlights and Things to Do
1. Ice Art Created by Nature
Spring water from the rocks near the Arakawa River freezes in the winter cold and gradually grows, forming these icicles.
Unlike man-made ice formations, the curtain of ice created by nature is breathtakingly beautiful.
The crystal-clear ice shining in the light creates an atmosphere that feels like another world.
Because the shape of the icicles changes day by day depending on temperature and weather, each visit offers a different view.

- The best viewing season is usually from mid-January to mid-February. Conditions change with temperature and weather, so checking event and opening information before visiting is recommended.
2. Magical Night Illumination
During the nighttime illumination, the icicles are lit up, creating a dreamy atmosphere.
Light reflects off the ice, producing a different kind of beauty from the daytime view.
The illumination is held for a limited period only.
- Illumination period: Usually early January to late February (subject to change depending on ice conditions)
- Illumination hours: Weekdays 17:00-19:00 / Saturdays, Sundays, and holidays 17:00-20:00 (may change depending on weather and other conditions)
The venue may also have a viewing area and small shops, so you can enjoy the scenery with a warm drink in hand.
