Nagano Prefecture (長野県 Nagano-ken) is a prefecture of Japan located in the Chūbu region of the island of Honshu. The capital is the city of Nagano. Due to the abundance of mountain ranges in this area, the land available for inhabitance is relatively limited.
Nagano has impressive highland areas, including most of the Kita-Alps Northern Alps, Chu-Alps, and Southern Alps, which extend into the neighbouring prefectures. In addition to its natural scenic beauty and rich history, Nagano was host to the 1998 Winter Olympics, which gained the prefecture international recognition as a world-class winter sport destination, and a Shinkansen line to Tokyo.
