With a height of 311.3 meters, Sankakuyama (三角山) is a small mountain located in the Yamanote area of Nishi-ku, Sapporo. The mountain’s distinctly triangular shape gives it its name: ‘Sankaku-yama’ (with ‘Sankaku’ meaning ‘triangle’ and ‘yama’ meaning ‘mountain’ in Japanese). At the summit, there is a triangulation station named ‘Mt. Kotoni’. Additionally, in the Ainu language, the mountain is called ‘Hachamuepui,’ which means ‘a small mountain of Hassamu’.
There are several hiking trails and a small rest house near the summit of Sankakuyama. Most of the trails are gentle, making them accessible for young children and seniors. It takes less than an hour to hike from the base to the mountaintop, making Sankakuyama a popular destination for locals.
You can reach Okurayama, home to the famous Ski Jump Stadium, by hiking through Sankakuyama. Conversely, you can access Sankakuyama from Okurayama by taking the lift to the observation platform of the jump stadium.
There are two entrances to Sankakuyama: the Yamanote and Miyanomori entrances. The Yamanote entrance offers convenient amenities, including parking and restrooms, along with helpful equipment and supplies to make your hike easier. Near the Yamanote entrance, you’ll find Sato Apple Farm, a charming apple orchard.
