Okaya (岡谷市 Okaya-shi?) is a city located in Nagano Prefecture, Japan. It was founded on April 1, 1936.

As of May 1, 2011, the city has an estimated population of 52,556, with 19,536 households and a population density of 616.93 persons per km². The total area is 85.19 km².

The city is twinned with Mount Pleasant, Michigan, USA, and in 2005 donated forty trees to it, honoring forty years of association between the two cities.[1]

From the Meiji period through into the start of the Shōwa period (1868-1930), Okaya was one of Japan's largest producers of export-quality silk, thanks to the introduction of a new silk-reeling machine from overseas.[citation needed]

After the second world war, Okaya established itself as a city of precision machinery, focusing on the manufacturing of products such as watches and cameras.

The region's local industry is predominantly made up of medium and small-sized businesses, but also some big-name businesses such as Seiko Epson, Olympus and Kyocera.

In addition, the city is known for its Onbashira and Taiko Festivals, as the birthplace of modern day skating[citation needed], and unagi (eel) dishes.
