Kurumayama Weather Radar Station

Kurumayama Weather Radar Station is a meteorological facility located in the mountains of Nagano Prefecture at approximately 1925 meters elevation. It uses radar equipment to track weather patterns and precipitation changes across the mountainous region.

The station began operations on November 1, 1999, representing a major advance in weather monitoring for the Nagano region. This enabled improved forecasts for the complex weather patterns in the mountains.

The station facilitates educational programs for local schools, contributing to the community's understanding of meteorological sciences and weather forecasting technologies.

The facility sits in a mountainous area, so visitors should expect mountain roads and changing weather conditions. The best time to visit is during drier months when the roads are easier to traverse.

The high elevation allows the station to observe weather events above cloud level, which is especially important for predicting mountain weather patterns. This vantage point reveals weather changes that lower stations cannot detect.
