The Notori-ko Sango-so Grassland, located on the shores of Lake Notori in Abashiri, Hokkaido, is one of Japan's largest habitats for Sango-so (Kochia verticillata). As autumn approaches, the Kochia grass growing in the wetlands turns a vivid, deep crimson, creating a magnificent landscape that looks as if a red carpet has been spread across the earth. This intense contrast of colors is a sight seen only during this season and is powerful enough to leave visitors in awe.
The plant commonly known as Sango-so (or Kochia) is a salt-tolerant plant perfectly adapted to this environment. This ecosystem, formed over many years alongside the natural environment of Lake Notori, serves as a symbol of the region's natural beauty. The changing expressions of the lakeshore landscape throughout the seasons are a vital part of the natural cycle that defines the essence of Hokkaido.

The greatest attraction is undoubtedly the sight of the deep crimson Sango-so grass in autumn. The striking contrast between the blue of the lake and the vibrant red covering the ground makes this an incredibly popular spot for photography. Gazing upon this vast red carpet is a unique experience found nowhere else. The shifting colors of the vegetation offer a precious opportunity to feel the raw vitality of nature.
The most recommended time to visit is the autumn season from late August through October. The best time to witness the most intense red coloration is during the bright daylight hours, when the contrast against the blue sky is at its peak. Visiting during the evening/sunset can also be magical, as the changing light deepens the red hues for a more dramatic effect.

Visitors can enjoy leisurely strolls through this vast natural landscape, feeling the changing seasons through sight and touch. Occasionally, local events such as the 'Notori-ko Sango-so Festival' are held, providing opportunities to experience the local nature through special community-led activities.
There are many other attractive sightseeing spots around Lake Notori. On the way to Abashiri city, you can visit facilities for experiencing drift ice or various historical museums, making it easy to include this site in a broader eastern Hokkaido travel itinerary. Since the area is easily accessible by car, it is a popular stop for a scenic driving tour.

As this is an outdoor natural environment, please prepare for changing weather conditions. It is important to wear seasonal clothing and comfortable walking shoes.
