Basic Information about Tokachi Peak
Geography and Location
Tokachi Peak spans the Kamikawa District in Biei Town and Kamifurano Town in Hokkaido, as well as Shintoku Town in the Tokachi District. Situated on the eastern side of the Furano Basin, it serves as the central feature of the Tokachi Peak Range in the southwestern portion of Daisetsuzan National Park.
Basic Data:
- Elevation: 2,077 meters
- Location: Kamikawa County, Biei Town, Kamifurano Town, Hokkaido; Tokachi County, Shintoku Town
- Mountain Range: Tokachi Peak Range (Tokachi Volcanic Group)
- Type: Active volcano (continuously monitored volcano)
- Latest Eruption: 1988-1989
Etymology of the Mountain Name
The name Tokachi Peak is said to derive from the Ainu word “Tokapuchi,” which means “breast-shaped mountain,” as the mountain’s rounded form resembles a breast. Another theory suggests the name comes from the fact that it is the representative mountain of the Tokachi region, thus becoming known as “Tokachi Peak.”
Value as One of Japan’s One Hundred Famous Mountains and Flower Mountains
Tokachi Peak is featured in Fukutada Kyuya’s One Hundred Famous Mountains and is also selected in Tamaki Sumie’s “Flower Mountains of Japan.” During the summer months, alpine flowers of various colors bloom magnificently, and especially from July through August, flowers such as Ezo Cuckoo Flower, Chinguruma, and Iwa Bukuro delight climbers’ eyes.
History of Tokachi Peak’s Volcanic Activity
Characteristics as an Active Volcano
Tokachi Peak is currently an active volcano and has been designated a continuously monitored volcano by the Japan Meteorological Agency. Volcanic smoke constantly rises from the summit, and its rugged rocky terrain speaks to the intensity of volcanic activity. The Tokachi Peak Range has experienced volcanic activity spanning approximately 3 million years, and this long history has shaped the majestic mountain landscape we see today.
The Major Eruption of Taisho 15 (1926)
The most catastrophic event in Tokachi Peak’s history was the major eruption on May 24, 1926. This eruption generated a snow-melt-induced lahar that swept through the Biei River and Furano River basins.
Damage Statistics:
- Deaths and Missing: 144 people
- Injured: Multiple
- Houses Completely or Partially Destroyed: Approximately 400
- Agricultural Land Damage: Severe
This disaster informed all of Japan about the dangers of snow-melt lahars caused by volcanic eruptions. Today, a natural disaster memorial stone for the Taisho mudflow is installed in Kamifurano Town to convey this tragedy to future generations.
Volcanic Activity Since the Showa Period
After the major eruption of the Taisho era, Tokachi Peak has experienced multiple eruptions.
- 1962 (Showa 37): Eruption on June 29, generating small-scale mudflows
- 1988-1989 (Showa 63-Heisei 1): Small-scale eruption activity
- 2004 (Heisei 16): Heightened volcanic activity led to increased volcanic alert levels
Volcanic earthquakes and fumarolic activity continue to be observed, and 24-hour surveillance by the Japan Meteorological Agency continues. It is essential to check the latest volcanic information before climbing.
History of Sulfur Mining
Sulfur mining was conducted on Tokachi Peak from the Meiji era through the early Showa period. Sulfur was abundant around the fumaroles near the summit and was an important industrial resource at the time. However, due to the 1926 major eruption and economic considerations, sulfur mining gradually declined and is no longer conducted. Mining sites remain visible along the climbing trail today, offering evidence of industrial activities from that era.
