Nestled deep in the lush, forested region of Tsubetsu Town—where woodlands cover most of the landscape—Lake Chimikeppu is a secluded, mystical lake hidden within untouched nature. Surrounded by a pristine forest that has thrived since ancient times, this hidden gem is home to a rich variety of wild birds and wildlife. The name "Chimikeppu" comes from the Ainu language and is said to mean “a place where water flows out through a broken cliff.”

Formed About 10,000 years ago by a landslide that dammed a valley stream, Lake Chimikeppu is believed to be a natural dam lake. It is also known, alongside Lake Akan, as one of the original habitats of Himemasu—a landlocked variety of sockeye salmon locally known as chip in Hokkaido. The fish is prized for its reddish flesh and superb flavor, and is said to be among the tastiest of all trout and salmon species. Whether grilled with salt, served as sashimi, or deep-fried, Himemasu is a must-try delicacy for gourmet travelers.

The northeastern shore of the lake offers a peaceful campsite for nature lovers, while the eastern shore is home to the exclusive Chimikeppu Hotel—the only accommodation on the lake.

Even today, Lake Chimikeppu quietly reflects the ancient forest around it, offering visitors a magical escape into the heart of untouched Hokkaido.
