Taishi Onsen is one of those quasi day use but it's also a ryokan places that attracts a lot of bathing for health and recuperation guests. The amazing very high quality spring is only poured into an indoor and outdoor bath, but with water this good you don't need a large selection of baths. The indoor bath has a giant mineral cone converted into a fountain that was taken from another natural spring. Something that the front desk admitted to me could not happen today. I walked from KaminoTaishi station to the spring and it took a good 40 minutes. There are free shuttle busses also from KaminoTaishi and Kawachikokubu Stations both on different Kintetsu lines. Discounted entrance after 5pm. Overall, Taishi Onsen great day trip from anywhere in the Kansai area.
