Most Kaiji (E257 series) services are formed of nine cars, numbered 3 to 11, with car 11 at the Kofu end. Cars 1 and 2 are added to some trains.
The seasonal Hamakaiji services are formed of 7-car 185 series EMUs based at Tamachi Depot in Tokyo, with car 1 at the Yokohama end.
The Kaiji service began on 1 October 1961 as a semi express operating between Shinjuku and Kōfu. The name was derived from the old name, Kai (甲斐?), of Yamanashi Prefecture. Services were operated using KiHa 58 series diesel multiple unit (DMU) trains in between duties on long-distance Alps and Hakuba express services. DMUs were used on these services due to the restricted tunnel clearances along the line prohibiting the use of electric trains. The outbound service departed from Shinjuku at 14:50, arriving at Kōfu at 17:19. The return working departed from Kōfu at 18:28, arriving at Shinjuku at 21:20. The Kaiji services were however discontinued and integrated with the Alps express services from the start of the revised timetable on 1 October 1965 when electric trains were introduced.
