Shinano Province

Shinano Province (信濃国, Shinano no kuni) or Shinshū (信州) is an old province of Japan that is now Nagano Prefecture.

Shinano bordered on Echigo, Etchū, Hida, Kai, Kōzuke, Mikawa, Mino, Musashi, Suruga, and Tōtōmi Provinces. The ancient capital was located near modern-day Matsumoto, which became an important city of the province.

The World War II–era Japanese aircraft carrier Shinano was named after this old province.
