Furenko Lake is a vast brackish lake spanning the towns of Bektai and Nemuro in Hokkaido. Covering an area of approximately 52.1 square kilometers, it is the 14th largest lake in Japan. The lake is managed as part of the 'Notsuke-Furen Nature Park' alongside the Notsuke Peninsula and is a highly significant wetland registered under the Ramsar Convention. The surrounding area preserves untouched nature, serving as a vital ecological hub for numerous species of wildlife and plants.
The name Furenko is derived from the Ainu word 'Hure-pe' (Red River). This name originated from the presence of 'yachi' (red soil) in the riverbeds, which caused the flowing water to appear reddish. This deep connection between the landscape and its name has been preserved through the ages. Furthermore, local communities have long engaged in reforestation movements along surrounding rivers, such as the Furen, Betoga, and Yausubetsu Rivers, to protect fish populations and maintain the delicate ecosystem.

The defining feature of Furenko Lake is the seamless integration of the sky, the lake, and the surrounding wetlands. The scenery changes dramatically with each season, offering breathtaking views that captivate all visitors. You can observe the lush vegetation near the river inlets and watch various wildlife in their natural habitats. As a designated nature park, the walking paths allow you to visually experience the raw power of Hokkaido's wilderness. The area is also a known spot for observing rare birds, such as the Red-crowned Crane.
While beautiful year-round, the lake offers different charms depending on the season. From spring to summer, the greenery is vibrant and full of life. In autumn, the changing colors of the vegetation provide a rich palette, while winter brings a serene, silent landscape covered in snow. For the most spectacular views, visit during sunrise or sunset when the colors of the sky reflect beautifully off the lake's surface. Please be prepared for significant temperature fluctuations depending on the season.

Visitors can enjoy peaceful walks through nature and wildlife observation. The quiet environment offers a profound sense of disconnection from daily life. While you can observe birds and local fauna, please remember that this is a protected area; activities should be quiet and respectful of the environment. The focus is on observing the natural world without disturbing it.
