The area of present-day Ōtaki was part of ancient Shinano Province, and the name of Ōtaki appears in a 1504 record as part of the Chikuma region of Shinano. The present village of Ōtaki was incorporated on April 1, 1889 by the establishment of the modern municipalities system.

In 1917, construction begins on the Ōtaki Forest Railroad (王滝 森林鉄道) The railroad was discontinued on June 30, 1975. On May 1, 1968, Chikuma District was renamed Kiso District. On September 14, 1984 the 1984 Otaki earthquake caused a section of Mount Ontake to crumble and flow into the Ōtaki Valley, with 29 people reported dead or missing and 87 homes destroyed.


Though tourism remains the primary industry in Ōtaki, tourist numbers (including skiers and worshipers) have declined in recent years. After tourism, manufacturing jobs are the most prevalent, followed finally by agriculture. Ōtaki is struggling economically, due in large part to public debt accrued through the building and management of Ontake 2240 ski hill. For 2008 roughly 3/4 of Ōtaki's annual budget is slated for administrative and financial operations, with almost a quarter of this being used to pay back public debt. This leaves only a fraction of funds for use in providing basic services such as sanitation, health, and education. Major cuts have been made to the salaries of village employees and to money spent social, cultural, and educational activities.[citation needed]
