Notoro-ko Coral Grass Colony

Japan's largest coral grass colony that turns crimson in autumn

Coral grass colony at Lake Notoro in Abashiri City, boasting the largest scale in Japan.

Coral grass, officially named Akkeshi-so, grows naturally in the wetlands along the lakeside as a salt plant. From spring to summer it is green, but in autumn the entire area turns vivid crimson, dyeing the lakeside in a burning red. Wooden walking trails are maintained, and you can walk through the coral grass that spreads like a red carpet while observing its beauty up close. When the wind blows, the small grass sways like waves, and the red colors reflected on the lake surface catch the eye.

The contrast between Lake Notoro's quiet water surface and the crimson coral grass spreading across the entire area is a landscape that symbolizes autumn in Hokkaido. The color contrast of the blue sky, blue lake, and red coral grass leaves a strong impression on visitors. As Japan's largest colony, it shows the art of nature representing autumn in Hokkaido.
