The area of present-day Murayama was part of ancient
Dewa Province. After the start of the
Meiji period, the area became part of
Kitamurayama District, Yamagata Prefecture. The town of Tateoka was established with the establishment of the modern municipalities system on April 1, 1889. The city of Murayama was established on April 1, 1954 with the merger of Tateoka with the villages of Nishigo, Okura, Tozawa, Okubo and Fumoto. Murayama became the registered host town for the
Bulgarian
