The area around Sai was inhabited by the Emishi people until the historical period. During the Edo period, it was controlled by the Nambu clan of Morioka Domain and prospered due to its timber industry and as a ferry terminal to Ezo. During the post-Meiji restoration cadastral reform of 1 April 1889, Sai Village was proclaimed from the merger of Sai hamlet with neighboring Chōgō hamlet.
