The Akita Shinkansen (秋田新幹線) is a Mini-shinkansen rail line in Japan. Serving the Kantō and Tōhoku Regions of the country, it links Tokyo and Akita in Akita prefecture. From Tokyo to Morioka in Iwate prefecture, it operates on the Tōhoku Shinkansen tracks. From Morioka to Ōmagari, it uses the Tazawako Line tracks. The section from Ōmagari to Akita use the Ōu Main Line tracks.
Services consist of Komachi trains formed of 7-car E6 series mini-shinkansen sets coupled with E5 series Hayabusa trains for the portion of the journey between Tokyo and Morioka.
The Komachi services run at a maximum speed of 320 km/h (200 mph) on the Tohoku Shinkansen, and between Morioka and Akita, run as 7-car independent trains with a maximum speed of 130 km/h (80 mph). However, 110 km/h (70 mph) is more typical for the line through the hills east of Akita, with trains slowing frequently to 90 km/h (55 mph) for curves such as those south of Ugo. The line from Morioka to Akita is prone to deep snow.
Between Tokyo and Morioka, the stations are the same as those on the Tohoku Shinkansen. From there on, the stations are as shown below.
