Mie Prefecture (三重県 Mie-ken) is a prefecture of Japan, which is part of the Kansai region on the main Honshu island. The capital is the city of Tsu.
Mie Prefecture forms the eastern part of the Kii Peninsula, and borders on Aichi, Gifu, Shiga, Kyoto, Nara, and Wakayama. It is considered part of the Kansai and Tōkai regions due to its geographical proximity to Aichi Prefecture and its cultural influence from Kansai, such as the fact that Kansai dialect is spoken in Mie. Traditionally, though, the Iga region of Mie is considered to have always been a part of Kansai.
