The area of present-day Higashikushira was first settled by peoples of the
Jōmon and
Yayoi cultures in the prehistoric period. Numerous archaeological sites in the town date from this period, including the "
Tōjinkofun," the ancient tomb of Tojin. Higashikushira was part of ancient
Ōsumi Province. During the
Edo Period, the area was part of the holdings of
Satsuma Domain. The village of Higashikushira established on May 1, 1889, with the creation of the modern municipalities system. On October 1, 1932, it was promoted to town status. Despite the recent national trend of towns and cities merging to form larger administrative units, the residents of Higashikushira voted to remain an independent township. Although various proposals were discussed, ranging from a merger with several local towns to absorption into the greater Kanoya city area, residents declined all options in favor of retaining local administration. ==Government==
