Iyo-Shirataki Station started its operation on February 14, 1918. At this time this station was known as Kaya Station (加屋駅 Kaya Eki?) but on April 1, 1950, it was renamed to Iyo-Shirataki Station. This name Iyo-Shirataki comes from the falls named Shirataki (白滝), which you can reach from this station on foot today. Iyo is the old name for the province in which this station is located.
At the time when this station opened, this station was located at the other place. This station was moved to the present location on July 16, 1928.
