The Nakaya Ukichiro Museum of Snow and Ice is one of Kaga's more unusual museums, dedicated to the scientist who created the first artificial snow crystals. The subject sounds narrow, but the displays make it tangible through snow-crystal forms, ice experiments, and the physics of weather made visible at a human scale.
The building sits by Lake Shibayama, which gives the visit a calm setting away from the onsen streets. It is a particularly good stop in poor weather or with curious children, and it pairs well with Kaga's hot-spring culture: one attraction is all steam and soaking, the other is cold, structure, and patient observation.
