Sounkyo Ice Waterfall Festival (Hyobaku Matsuri) & Lake Shikotsu Blue Ice Festival

Schedule: Akhir Januari - Pertengahan Maret (Sounkyo) & Akhir Januari - Akhir Februari (Danau Shikotsu) | Location: Hokkaido (北海道)

Deep inside the towering volcanic cliffs of Daisetsuzan National Park, the **Sounkyo Onsen Ice Waterfall Festival (Hyobaku Matsuri)** harnesses the fierce sub-zero winds of the Ishikari River gorge to construct a sprawling 10,000-square-meter fortress of solid ice. Over three months prior to opening, crews spray pure river water onto timber scaffolds amidst freezing gales, allowing the mist to freeze organically layer by layer into towering 13-meter ice castles, stalactite caverns, ice slides, and an ice shrine where visitors press lucky coins onto frozen pillars. After nightfall in Sounkyo Gorge, the labyrinth of organic ice waterfalls and multi-story frozen pavilions is bathed in vibrant rainbow illuminations against the pitch-black alpine sky, capped by winter fireworks (*Hyobaku Fireworks*) whose echoes reverberate dramatically off the surrounding canyon walls before guests soak in the steaming outdoor baths of Sounkyo Onsen. Meanwhile, just 40 minutes from New Chitose Airport, the **Lake Shikotsu Ice Festival (Chitose Lake Shikotsu Hyoto Matsuri)** showcases a breathtaking daytime and nighttime transformation. Built by spraying water drawn directly from Lake Shikotsu—repeatedly ranked as having the purest water quality of any lake in Japan—the towering ice domes, frozen moss tunnels, and crystalline spires glow with a translucent, natural azure hue known as **"Shikotsuko Blue"** under the daytime sun, before transforming into an illuminated crystal wonderland after dusk.
