芦ヶ久保の氷柱

The Ashigakubo Ice Pillar is a man-made winter attraction located in Yokoze Town, Saitama Prefecture, in the Chichibu region. Created annually since 2014, the ice formations are produced by spraying water from the nearby Yokoze River over wooden frameworks during freezing winter temperatures. The water freezes in layers, gradually building massive ice structures that can reach heights of over 10 meters and widths spanning 30 meters. This winter spectacle was developed to attract visitors during the coldest months and has become a signature seasonal event in the Chichibu area.

The ice pillars represent a modern interpretation of natural ice formations found in mountainous regions, adapted as a controlled tourist attraction. The site demonstrates how freezing temperatures in the Chichibu mountains, typically ranging from -5°C to -10°C during peak season, can transform continuously flowing water into dramatic ice sculptures. The artificial creation process allows reliable annual displays unlike unpredictable natural ice formations, making the phenomenon accessible to general visitors rather than requiring mountaineering experience.

Visitors to Ashigakubo Ice Pillar walk along designated pathways through the frozen landscape, observing ice columns, curtains, and clustered formations up close. Evening illuminations feature colored LED lights that transform the ice structures into vibrant blue, purple, and rainbow-hued displays, creating photography opportunities distinct from daytime visits. The site operates during winter months, typically from early January through late February when temperatures remain sufficiently low. Warm beverages and local food vendors operate near the entrance area, and wooden walkways provide stable footing on potentially slippery terrain.

The attraction is located near Ashigakubo Station on the Seibu Chichibu Line, approximately 10-15 minutes on foot from the station platform. From central Tokyo, visitors take the Seibu Ikebukuro Line or Seibu Shinjuku Line to Seibu Chichibu Station, then transfer to local trains stopping at Ashigakubo, with total travel time around 90-120 minutes. Admission fees typically range from ¥300 to ¥500 for adults, with reduced rates for children.
