Located in Ubaranai on the southern shore of Lake Notoro, the "Lake Notoro Glasswort community" boasts the largest colony of Glasswort, also known as glasswort, in Japan. Known as a natural landscape, it is carefully preserved and protected by local residents.
The greatest attraction of this cluster of plants is the magnificent scenery that unfolds in autumn. Every year from late August to late September, Glasswort, which grows in clusters across approximately 4 hectares, turns a beautiful coral-like red, reaching its peak. The sight is described as "like a bright red carpet laid out," and is breathtakingly beautiful. You can also enjoy the fantastical contrast with the blue sky.
At Lake Notoro Glasswort community, a wooden boardwalk has been installed so that visitors can walk to the middle of this vibrant red landscape, which offers a different kind of beauty than autumn foliage. Furthermore, in August 2015, after overcoming poor growth, the colony was declared to have recovered thanks to the efforts of the entire Abashiri group, including seed collection and improvements to the lake's water inflow and outflow.
In mid-September, when the coral grass is at its most vibrant red, the "Lake Notoro Coral Grass Festival" is held, attracting many tourists.
