Wada-shuku (和田宿 Wada-shuku?) was the twenty-eighth of the sixty-nine stations of the Nakasendō highway connecting Edo with Kyoto during the Edo period. It was located in the present-day town of Nagawa, in the Chiisagata District of Nagano Prefecture, Japan.
Located at an elevation of 820 m (2,690 ft), at the entrance to the Wada Pass, which was considered one of the most difficult portions of the highway because of it steepness. Because Shimosuwa-juku, the next post station, was over 20 km (12 mi) away, Wada-shuku flourished with over 150 buildings to accommodate all of the travelers and their pack animals. Wada-shuku was approximately 49 ri, 24 chōfrom the starting point of the Nakasendō at Nihonbashi, or about 195 kilometers.
Per a 1843 guidebook issued by the Inspector of Highways (道中奉行 Dōchu-būgyō?), the town had one honjin, twowaki-honjin, and 28 hatago, with a total resident population of 522 people.
