Illuminations are one of the highlights during Japan's winter season, but it's not only during winter that you can enjoy them. Many regions that receive substantial snowfall during winter opt to have their illumination events during green season, including the Adatara Kogen Ski Resort in Fukushima.
Running for over 10 years now, the illuminations have become one of the area's summer traditions, and the light displays include motifs of flowers and animals, constellations, and even a vibrant rainbow LED "river" running down the mountainside.
