Looking for fully tattoo-friendly ryokan with public bath

I searched through the subreddit history and didn't find much information from the past 5 years that really answered my question. I'm looking for an overnight stay in a place with public hot spring bathing that allows uncovered tattoos in public baths. My options are Tokyo, Kyoto, Osaka, Hakone, or Nagoya. Does anyone have any recent experience with this? I know I'm looking for a unicorn, but I'm hoping there's one out there.

Additional question: if I stay at a ryokan with private baths, how will they know if I have tattoos?
