Shimosuwa (下諏訪町, Shimosuwa-machi) is a town located in Nagano Prefecture, Japan.

[2] Per Japanese census data,[3] the population of Shimosuwa has been declining at a low but accelerating rate over the past 50 years.

The village of Shimosuwa was created with the establishment of the modern municipalities system on April 1, 1889 and was raised to town status on June 30, 1893.

The Harumiya (春宮) and Akimiya (秋宮) shrines are symbolically renewed every seven years during the Onbashira festival.

Huge trees are cut in a Shinto ceremony, then the logs are dragged from the mountains down to the shrines.
