Located in front of Jōetsu-Myōkō station this is a recently built (as of 2020) supersento, along with the entire area which has grown up since the Hokuriku Shinkansen station was opened here in 2015. The supersento appears to be run by a local housing developer who has land on this side of the tracks. Inside there is not much other than the baths. No restaurant and only a small sitting area before the changing rooms, so it is hard to call this a supersento. Inside there is also a limited selection of baths, but they use what they have very well. The main bath is separated into a shallow and a deep section that is deeper than usually found. Outside is a smaller shallow outdoor bath that has no sky view. Given the snow blowing across the plains when I went, I feel this was a good design choice. Upstairs is a salt and dry sauna (extra fee) and a cold-water bath. However, the key to this place is the amazing spring water filling the tubs. This was one of the slipperiest feeling baths I have been in. It is presented on the warmer side also making visiting here in the snow even more of a pleasure. Even the kakari basin was filled with the lovely spring water. Getting here is not even a 5-minute walk from the station so I was able to arrive on the Shinkansen, take a bath and get back to take the next departure one hour later. Granted, it was a bit rushed, but it is totally doable.
