Overview
Kurokawa Onsen Yamamizuki is a mountain-valley inn in the Oku-Kurokawa area of Kurokawa Onsen, in Minamioguni-machi, Kumamoto. Separate open-air baths for men and women sit along the stream of the Tanohara River, and you can also choose rooms with a semi-open-air bath or an indoor bath. Dinner and breakfast are served in Kahenpen, a semi-private dining room reserved for your group; elementary school children choose a special kids' plate or a steak plate, and preschool-age children are served a kids' meal. Co-sleeping is available for up to 2 children, with rates that differ depending on whether meals and bedding are included. The inn is not barrier-free, so it is best to check in advance if you will be getting around with a stroller.

Baths and Onsen
The onsen flows straight from the source, with open-air baths along the mountain stream: Yukoku-no-Yu for men and Mori-no-Yu for women.

There are 3 private-hire baths in various sizes, available on weekdays from 2 p.m. to 8 p.m. for an additional charge. The spring water is a simple onsen, a hypotonic, weakly acidic, high-temperature spring that is said to be mild and gentle on the skin. Staying guests can also use the onsen at the sister inns Shinmeikan and Miyama Sanso free of charge, in addition to the baths here.
