From 17 March 2012, station numbering was introduced on all Tōbu lines, with Shimo-Imaichi Station becoming "TN-23".[2]
A turntable was installed next to the station in 2016 for turning the steam locomotive used on steam-hauled tourist trains operating between Shimo-Imaichi and Kinugawa-Onsen since August 2017.[3] The turntable was acquired from the JR West Nagatoshi Station in Yamaguchi Prefecture.[3] A two-stall engine shed to house the steam locomotive was also constructed adjacent to it. At the same time, the station was renovated to architecturally resemble a Japanese railway station from the Showa era.
