Kakkonda no Ōiwaya

Kakkonda no Ōiwaya is a natural monument in Shizukuishi featuring impressive rock formations with complex geological structures and mineral patterns. The rocks were created over millions of years through natural processes and shape the local landscape.

The rock formations developed through extensive erosion during the Quaternary period and have shaped the regional landscape since then. This geological history shows how water and weather reshaped stone over very long timescales.

The site holds meaning in local teaching about geology and how the landscape was shaped. People visit to understand the natural processes that created the rock formations visible today.

The site can be reached from Shizukuishi station using local transportation, with hiking trails leading directly to viewing areas. Visit during dry weather since the paths can become slippery.

Scientists study the geothermal fluids here to understand connections between underground heat sources and the rock formations above. This research reveals how hidden underground processes shape what visitors see at the surface.
