Tachibana-yu has been remodeled but it was done in a very retro style. This is a great bath to just go and look around the entrance and shoe boxes. Inside the bathing area is quite small, but nicely laid out. The medicated bath near the front is probably the best. This bath treats its water with radon so if you are worried about exposure, you might want to avoid this sento. Overall Tachibana-yu is a great promoter of sento culture. The owners are proud of their little bathhouse and it shows. On their website they have a page with letters of recommendation and thanks from the local government and other organizations, but they also have one from the local primary school that visited. So cute!
