Mt Teshio

Mt Teshio (Japanese: 天塩岳) stands in the far north of Hokkaido, a long, quiet nihyakumeizan* mountain rising above the upper reaches of the Teshio River and forming part of the remote highlands that stretch toward the Sea of Japan. It is not a dramatic peak in the volcanic sense, but instead forms a broad, forested massif shaped by ancient uplift and long erosion. Its topography is gentle yet expansive with wide ridges, deep valleys and a summit area that opens into airy clearings. It is a mountain that feels far from everything, defined by the vastness of Hokkaido’s interior.

​

The mountain’s significance lies in its isolation. Mt. Teshio is one of the major peaks of northern Hokkaido, a landmark in a region where settlements thin out and the forest becomes immense. Because it stands alone, the summit offers a rare northern panorama: the Rumoi coast shimmering to the west, the Kitami highlands rising to the east, and the endless forests of Hokkaido stretching north.

​

The flora and fauna reflect this northern remoteness. This is an area of massive snowfall. The lower slopes are wrapped in dense mixed forest while the upper ridges host dwarf pine, hardy shrubs and alpine flowers that bloom briefly in summer. Wildlife is abundant, and Teshio is home to a large number of brown bears that demand caution from hikers. I didn't see a bear when I was there, but I saw their droppings on numerous places throughout the hike. It was quite unnerving.

​

The hiking course to Mt. Teshio is long and atmospheric. Most begin from the mountain hut at the end of a long forest road. I stayed the night here before making my ascent. The climb is steady rather than steep, unfolding past a fast-flowing river and through cool, quiet woodland before emerging onto the broad upper slopes. The final approach to the summit is gentle, leading to an open crest. It's possible to return to the hut via a loop course.
