Yamagata Domain
Yamagata Domain (山形藩, Yamagata-han) was a feudal domain in Edo period Japan, located in Dewa Province (modern-day Yamagata Prefecture), Japan. It was centered on Yamagata Castle in what is now the city of Yamagata. Unlike some han whose control was relatively stable throughout the Edo period (1603–1867), Yamagata changed hands a great number of times during its history.
