Verified Timeline
Lore & Background
The aboriginal Ezo people once inhabited the area now known as Yamagata. Yamagata and Akita Prefecture were known as Dewa Province until the Meiji Restoration. During the Heian period (794–1185), the Fujiwara family ruled the area. Yamagata City flourished during the Edo period (1603–1867) due to its status as a castle town and post station, famous for beni (red safflower dye used in the production of handspun silk). In 1689, the famous haiku poet, Matsuo Bashō visited Yamagata during his five-month trip to the northern regions of Japan. Yamagata prefecture experienced its greatest growth period following the end of World War II, but then quickly began to slow down and eventually decline steadily. In May 2025, the Yamagata prefectural government announced that the estimated population had fallen below 1 million. This marks the lowest population level recorded in the prefecture since the 1920 census.
