Takayama tattoo friendly onsen

Looking for a tattoo friendly onsen around Takayama as I'll be going there for their spring festival next year.

I've got a sleeve that's not vulgar (no nudity or violence) but has a skull.

My Mrs has two small tattoos on inset of her arms.

Happy to cover them with whatever is needed (sleeve or stickers).

Any recommendations highly appreciated. Thanks
