Akatsuki, as an overnight
limited express service, was introduced on October 1, 1965, by
Japanese National Railways. It was operated between
Shin-Ōsaka and two destinations in
Kyūshū, namely
Nishi-Kagoshima (present-day Kagoshima-Chūō) and
Nagasaki. It was connected at
Shin-Ōsaka with the
Tōkaidō Shinkansen. In the 1960s, the operation of
Akatsuki was increased. Its maximum operation was 14 services (7 round-trips) a day in the mid-1970s, and all of them were connected with the
Tōkaidō Shinkansen. At the end of the 1970s, the number of
Akatsuki services was reduced due to decreasing ridership. From November 1986,
Akatsuki remains as only two services (one round-trips) a day. Due to falling passenger numbers, the service was discontinued in March 2008. ==Rolling stock==
