Form of Service

The entire line is under one name, but it actually operates in four separate segments.

Fukushima Station ~ Shinjo Station

Shinjo Station ~ Omagari Station This segment passes from Yamagata prefecture to Yuzawa, Yokote, Misato, and into Daisen. One train, either regular or express, will pass every hour or two.

Omagari Station ~ Akita Station The Akita Shinkansen also operates on this line and requires a wider rail gauge along this segment. Therefore, one will find three parallel rails along the tracks in this segment.

Akita Station ~ Aomori Station Except for some special and large trains, this segment is actually broken into three sub-segments: Akita Station~Ōdate Station, Ōdate Station~Hirosaki Station, Hirosaki Station~Aomori Station. Only two or three trains make the full trip from Akita Station to Aomori Station daily.
