Volcanoes, onsens, and Japan’s first geopark
Hanging out around active volcanoes, and the calderas of volcanoes that previously blew themselves up, has certain advantages. One clear benefit is that the hot magma associated with active volcanism heats groundwater that can rise to the surface to create hot springs. Hokkaido is crazy with hot springs. In Japan, onsen refers to the springs themselves and to the hotels...
Daisetsuzan National Park: the rooftop of Hokkaido
Daisetsuzan National Park was established in 1934, the oldest park in Hokkaido, along with Akan-Mashu National Park.

It is huge—at 2,267 km2 (875 miles2), it is the largest national park not only in Hokkaido, but in all of Japan. The Ishikari River, which...
Akan-Mashu National Park: nests of volcanoes and calderas

A crater is the depression on the top of a volcano where lava and/or pyroclastic materials spew forth during eruptions. But Crater Lake should actually be called Caldera Lake. Calderas are formed when volcanoes are so explosive that they blow off a major...
Shiretoko Peninsula: Japan’s “end of the earth”
One of the most remote parts of Japan, Shiretoko is derived from sir etok, meaning “the end of the earth” in the Ainu language. Ainu people lived in the region for thousands of years, but like indigenous groups worldwide, they were discriminated against, and largely obliterated when, in this case, the Japanese people moved into Hokkaido in the 19th century....

The culture and history are fascinating and—wow!—who doesn't enjoy the high quality food. For two earth scientists, learning more about the country's geologic makeup is another big draw. In Japan, no one is immune...
