65. Izumi-so, Gero Onsen Went with a tegata for higaeri (listed from 8 to 9 and 18 to 20). Very pleasant and positive staff. They gave a random discount on a small towel and a large towel rental, asking just 100 yen total, and the grandma-owner gave a compliment on my sneakers. The changing room and the baths themselves are very small. Indoor bath is hot+, outdoor is hot-. Water is clear, with a film effect on the skin afterwards. There are frog figurines. Honestly, compared to other onsens in Gero — skippable, but it's hard not to note the very warm attitude of the staff.
