Which of the listed prefectures is part of the Tohoku region?

The Tohoku region is located in the northeastern part of Honshu, Japan's main island. It is known for its distinct cultural heritage, natural beauty, and traditional sake production. Iwate, being part of this region, is renowned for its high-quality sake due to the region's climate and rice cultivation. The Tohoku region includes six prefectures: Aomori, Iwate, Miyagi, Akita, Yamagata, and Fukushima.

In contrast, the other prefectures listed, such as Aichi, Hyogo, and Osaka, are situated in different regions. Aichi is part of the Chubu region, while Hyogo and Osaka are located in the Kansai region. This geographical distinction is crucial when identifying which prefectures belong to the Tohoku region specifically. Therefore, recognizing Iwate's position within Tohoku underlines its cultural and historical significance in relation to sake and regional identity.
