Mt. Tossho

Experience a Sea of Katakuri in Bloom

A gentle 239-meter hill where a vibrant carpet of Katakuri flowers awakens with the spring thaw, offering a serene escape into Hokkaido’s rich natural heritage.


Located on the border of Asahikawa City and Pippu Town, this expansive forest is a precious "Satoyama"—a traditional woodland long preserved through a harmonious relationship between nature and local people. In late April, as the soft earth emerges from beneath the melting snow, the "Spring Fairies"—delicate Katakuri (Asian fawn lilies)—begin to bloom, covering the ground in a breathtaking sea of rosy purple. During this brief window before the forest canopy fills with leaves, sunlight pours onto the forest floor, illuminating the blossoms like a quiet, natural ballroom.


As you wander the walking trails, the crisp, cool forest air carries the earthy scent of spring. This woodland has a storied history, having been used for firewood and grazing since the Meiji era. This careful stewardship has helped maintain a healthy environment where sunlight reaches the ground, allowing life to flourish. By early summer, the energetic chorus of Ezo-haruzemi cicadas fills the air, and you might even spot a charming Ezo squirrel busily carrying bark through the trees. Even in winter, the forest speaks in whispers, with the crisp prints of foxes and Ezo deer etched into the pristine white snow. Rejuvenated over more than a century, this vibrant forest offers a fresh sense of wonder and a deep connection to the seasons with every visit.
