After Morioka, the Komachi service continues along standard gauge tracks that were converted from narrow gauge. Because it then runs on tracks that have grade crossings, its maximum speed from Morioka to Akita is, compared to on the Tohoku Shinkansen.

History

Komachi services began on the newly opened Akita Shinkansen line from the start of the revised timetable on 22 March 1997 using a fleet of 16 new 5-car E3 series trains running at a maximum speed of on the Tohoku Shinkansen. The name Komachi was officially announced in July 1996. Services initially consisted of 13 return workings daily between Tokyo and Akita, and one return working between Sendai and Akita. Most trains ran coupled with 200 series Yamabiko trainsets between Tokyo and Morioka, but three return workings ran coupled with newly introduced E2 series sets, running at a maximum speed of between Utsunomiya and Morioka, and giving a fastest journey time of 3 hours 49 minutes between Tokyo and Akita. The train services proved popular, and from the December 1998 timetable revision, an addition return working was added, and the E3 series trains were lengthened to six cars each. From the December 1999 timetable, all Komachi services ran together with E2 series Yamabiko trains, allowing overall journey times to be reduced, with a typical journey time of 4 hours 4 minutes.
From 16 March 2013, new Super Komachi services started, using new E6 series trains running at a maximum speed of on the Tohoku Shinkansen. Initially, a fleet of four trains was used to operate four return services daily between Tokyo and Akita. The fastest journey time was reduced to 3 hours 45 minutes, 5 minutes faster than the fastest previous Komachi services. From the start of the revised timetable on 15 March 2014, all services were operated by E6 series trains, and the name was returned to simply Komachi. At the same time, the maximum speed on the Tohoku Shinkansen was further raised to.
