Kasamatsu is an amazing old style sento. One bath in the middle of the room with a shallow and deep section. Only a few of the faucets along the walls have a shower. Very typical old style, but the unique thing about this sento is that the bathtub looks to have been recently remodeled (as of Feb 2020). So if you are a bit worried about some of the older baths but want to have that experience--this is the place. The changing room is the same old style that feels like an antique shop in the best way. Also there are two great great mosaics on the two walls along the back of the building. The smaller one is an abstract flower motif, while the second larger one is a Kansai style European lake scene. Highly recommended sento.
