About Lake Toya｜Charms of Hokkaido’s Representative Caldera Lake

Geography and Characteristics of Lake Toya

Lake Toya (Touya-ko) is a secondary river system lake belonging to the Chougawa River Basin, spanning the towns of Toyako in Abuta District and Sobetsu in Usugun District. The lake is approximately circular in shape, measuring about 11 kilometers east to west and 9 kilometers north to south, with a surface area of approximately 70 square kilometers. With a maximum depth of about 180 meters, it is also known as the 6th deepest lake in Japan.

As a caldera lake, it ranks as Japan’s 3rd largest after Lake Kussharo and Lake Shikotsu. In the center of the lake are four islands formed by volcanic activity (Oshima, Benzuten Island, Kannon Island, and Manjū Island), collectively referred to as “Nakajima.”

Origin of the Name Lake Toya

The name “Toya” derives from the Ainu word “To-ya,” meaning “lake shore” or “water edge.” Named by the indigenous Ainu people who lived in this area long ago, this beautifully resonant name continues to be cherished as part of the region’s identity.

Value as a World Geopark

The Lake Toya area is designated as part of Shikotsu-Toya National Park. In 2008, it was certified as the “Lake Toya-Usu Mountain Geopark” in the Japan Geopark Network, and in 2009, it became Japan’s first site to be registered as a UNESCO Global Geopark.

This recognition honors the geological significance of the unique landforms created by active volcanoes such as Mount Usu and Showa Shin-zan, as well as the area’s valuable record of volcanic history. It stands as a globally important natural heritage where visitors can experience the workings of the Earth up close.

History of Lake Toya｜Landscapes Created by Volcanic Activity

Birth of the Caldera Lake

Lake Toya was born approximately 110,000 years ago from a massive volcanic eruption. When magma from underground was expelled during this eruption, the resulting void below ground collapsed, forming a giant depression called a caldera. Over time, rainwater and groundwater accumulated, eventually creating the beautiful lake we see today.

Activity of Mount Usu and Showa Shin-zan

Mount Usu, which rises on the south shore of Lake Toya, remains an active volcano today. In the 20th century alone, it experienced four eruptions: in 1910, 1944-45, 1977-78, and 2000.

Particularly notable was the eruption from 1943 to 1945, during which Showa Shin-zan was born as the land rose. The emergence of a mountain reaching 398 meters in elevation in just two years is recognized worldwide as a rare geological event.

Development as a Hot Spring Resort

The history of Lake Toya hot springs dates back to the Meiji era. Development as a hot spring resort began in the early 1900s, and it has grown into a premier resort destination by leveraging its beautiful lakeside setting and abundant hot spring resources. Today it has become one of Hokkaido’s leading hot spring tourism destinations, welcoming visitors throughout the year.
