The Tohoku region (東北地方; Tōhoku-chihō) is a geographical area of Honshu, the largest island in Japan. The area is also known as Michinoku (みちのく).

The last stronghold of the indigenous Ainu on Honshu and the site of many battles, Tohoku retains a reputation as a remote and backward region, offering breathtaking scenery but a harsh climate. Tohoku is immemorialized in haiku poet Matsuo Basho's work Oku no Hosomichi (The Narrow Road to the Deep North).

The region consists of six prefectures: Akita, Aomori, Fukushima, Iwate, Miyagi and Yamagata.
