Kuroba Onsen

A small onsen in the Toyama mountains with a magnificent view of the river and mountains. On the women's side there's no fence — on one side there are boards angled so they look like a fence from outside, but from inside you can see through the gaps and the view is barely obstructed. And from the front it's completely open, because across the river there's a mountain covered in wild, barely passable forest. Located in the middle of nowhere, visitors are mostly locals, very cute and cozy, quite spacious for the number of people. There's a small restaurant with local cuisine too. Fully equipped, shampoo and towel rental available. Not too hot, very comfortable even in summer. Temperature is 42 degrees, perfectly comfortable for me — not scorching but warms you up nicely. Colorless and without a strong smell. I didn't check this time, but before the pandemic they were tattoo-friendly — I went there with friends for whom that matters. But all the onsens in these mountains were tattoo-friendly back then.
