History The area of Higashikagawa was part of ancient Sanuki Province. From the Heian period the Hiketa port prospered as a good natural harbor and a gateway to Shikoku from the Kinai region. From the Sengoku period, Hiketa Castle was a stronghold of the Ikoma clan and a castle town developed around the fortifications. Even today, many of the intricate alleyways and old buildings from the Edo and Meiji periods still exist, preserving the atmosphere of a pre-modern fishing town. During the Edo Period, this area was part of the holdings of Takamatsu Domain. Following the Meiji restoration, the area was organized into villages within Ōchi District, Kagawa with the creation of the modern municipalities system on February 15,1890. Hiketa was elevated to town status on October 1, 1909. The city of Higashikagawa was the result of a merger on April 1, 2003 between Hiketa and the towns of Ōchi and Shirotori, both from Ōkawa District (which was dissolved as a result of the merger). Government Higashikagawa has a mayor-council form of government with a directly elected mayor and a unicameral city council
