FYI the is Hotel Fugetsu. The taxi at the station took a while to figure out when I showed them the name of the hotel.
The senior check in staff was not helpful when we tried to book 2 taxis to Umi Jigoku hot spring. It was a 20 minutes walk uphill and 2 of our group were unable to walk that distance. They claimed the taxis would not take us due to the short distance.
Also they were going to charged us extra for exchange of wet towels.
