Tomiya is located in central Miyagi Prefecture, bordered by the Sendai metropolitan area to the south.

The area of present-day Tomiya was part of ancient Mutsu Province, and has been settled since at least the Jōmon period by the Emishi people.

The village of Tomiya was created on April 1, 1889 with the post-Meiji restoration establishment of the modern municipalities system.

This district representation plays a vital role in ensuring Tomiya's interests are voiced in national legislative matters.

[citation needed] Tomiya has two mascots, Buruberi Musume (ブルベリッ娘, lit: Blueberry Girl) and Burupiyo (ブルピヨ).

Tomiya makes a lot of merchandise of the mascots, including stickers on the Japanese social media LINE.
