The wild lily of the valley habitat that spreads out in Memu, Biratori Town, at the foot of "Mount Poroshiri" in the Hidaka Mountains Erimo Tokachi National Park, boasts an area of approximately 15 hectares, making it the largest in Japan. This area was once a pasture where military horses were grazed freely. The horses knew that the lily of the valley is poisonous and left them uneaten.

After that, the "Lily of the Valley Festival" was held and it was open to the public, but due to severe over-harvesting and trampling, from 1975 onward it fell into a state close to extinction, so public access was prohibited. Since then, we have strived for conservation management, and over many long years, we have been able to restore it to a state close to its peak.

We designated the lily of the valley as the town flower, established a viewing path within the habitat, and have been striving for thorough management. Currently, with the widening of the viewing path, development of photo spots, and the cooperation of volunteers, we are striving for environmental conservation, and it is open to the public only during the period from late May to early June.

We hope that everyone will see the dainty, strong, and beautiful appearance of the lily of the valley that we are proud of at least once, and spend a heart-warming moment.

The habitat in Biratori Town is home to a lily of the valley native to Japan [Japanese species] (whose flowers are hidden under the leaves), and its pure and lovely appearance, blooming quietly, is beloved.

The flower language of such a lily of the valley is "The Return of Happiness" and "Purity".
