Hokkaido | I came to Lake Toya just to see these two active volcanoes
I took the JR train from Sapporo to Lake Toya just to see these two active volcanoes: Mount Usu and Showa Shinzan. The former is an ancient active volcano, while the latter is a new volcano that emerged from flat land. Here, I experienced Hokkaido's most awe-inspiring field lesson on volcanoes.
🔴 Showa Shinzan
· Elevation: 398m. It is a parasitic lava dome of Mount Usu and a volcano whose birth from flat land was fully witnessed by humans. It is designated as a "Special Natural Monument" of Japan.
· Origin story: Before 1943, this area was a flat wheat field. After frequent earthquakes, the ground continued to rise. Over the course of two years, a reddish-brown volcanic peak was forced up from the wheat field, taking its final shape in 1945. Masao Mimatsu, the postmaster of Sobetsu at the time, meticulously recorded the mountain's daily growth, leaving behind invaluable geological records.
· Appearance: The entire mountain consists of exposed reddish-brown lava with almost no vegetation, and wisps of white smoke can still be seen rising from the summit today.
🌋 Mount Usu
· Elevation: 737m. It became active about 20,000 years ago and remains an active volcano today.
· Eruption history: It had 4 major eruptions in the 20th century, making it one of the most thoroughly observed and documented active volcanoes in the world.
· 1910 eruption: Meiji Shinzan was born, and the source of Lake Toya Onsen gushed out;
· 1943–1945 eruption: The wheat field at the foot of the mountain rose, and Showa Shinzan was born;
· 1977 eruption: The volcanic plume reached 12,000 meters high;
· 2000 eruption: For the first time, the Japanese government officially issued an emergency volcanic warning before an eruption. Over 16,000 residents were evacuated in advance, achieving zero casualties, which became a textbook case of modern volcanic disaster prevention.
🚠 Unique experience: Take the ropeway directly to the Mount Usu crater
Take the Mount Usu Ropeway to reach the summit observation deck in 6 minutes.
At the foot of the mountain, the crystal-clear waters of Lake Toya spread out, with Nakajima island floating quietly in the center. The reddish-brown Showa Shinzan nearby and Mount Yotei in the distance are clearly visible.
Pick up a simple hiking stick at the ropeway station entrance and walk along the summit trail to the crater observation deck. Seeing the white sulfurous smoke still slowly rising and smelling the faint scent of sulfur in the air, you can truly feel the "breath" of the active volcano at that moment.
Through years of continuous monitoring, humans have gradually learned to coexist with the restless earth. Perhaps we can never control volcanic eruptions, but through prediction, we can minimize the damage.
