The Akita Shinkansen (秋田新幹線) is a Mini-Shinkansen high-speed rail line on Honshu, the largest island of Japan. Serving the Kanto and Tohoku regions of the country, it links Tokyo Station and Akita Station (which is in the city of Akita, Akita Prefecture) with direct service. From Tokyo to Morioka (in Iwate Prefecture), it operates on the Tohoku Shinkansen tracks. From there to Omagari, it rides on the Tazawako Line tracks. The last segment of its journey takes place on the Oou Main Line.

The segment from Morioka to Akita began operating on March 22, 1997.

Komachi trains couple with Hayate (or sometimes Yamabiko) trains on the Tohoku Shinkansen for the portion of the journey between Tokyo and Morioka. Between Morioka and Akita, the Komachi runs as a six-car independent train. It uses E3 series rolling stock.

Between Tokyo and Morioka, the stations are the same as those on the Tohoku Shinkansen. From there on, the stations are as follows:

• Morioka
• Shizukuishi
• Tazawako
• Kakunodate
• Omagari
• Akita
