Ochiai-juku (落合宿, Ochiai-juku) was the forty-fourth of the sixty-nine stations of the Nakasendō. It is located in the present-day city of Nakatsugawa, Gifu Prefecture, Japan. The honjin and the sub-honjin, as well as some old street lights, remain from the Edo period. The Honjin were the main rest areas in old post towns and very few remain today.
