The area of present-day Yahiko was part of ancient Echigo Province, and developed as a settlement around Yahiko-jinja, a Shinto shrine which was established in the 8th century. The modern village was established within Nishikanbara District, Niigata on April 1, 1889 with the creation of the municipalities system. The present shrine was rebuilt in 1916. The earlier shrine buildings were destroyed by a 1912 fire which started in the village. It is the only village left in its district after the two towns from the same district merged into the city of Tsubame on March 20, 2006.

Yahiko has one public elementary school and one public middle school operated by the village government, but no public high school.
