The Misotsuchi Icicles – A Hidden Winter Wonder Tucked away in the mountains of northwestern Saitama Prefecture, the Okuchichibu area is a region blessed with rich nature and clear-flowing streams. About a 30-minute drive from Seibu-Chichibu Station, you’ll find a remarkable spot where nature creates a stunning work of ice art: the Misotsuchi Icicles. Formed when spring water flowing from rock faces freezes, these natural icicles rise to around 10 meters high and stretch roughly 30 meters wide.
