御所の湯
You can use the bath with your tattoos visible. Nothing to cover, no size limit, and nothing to declare at the desk.
No restrictions. Tattoos of any shape and size, nothing to cover.
All seven public hot springs in Kinosaki Onsen allow tattoos of all sizes, with no need to cover them up
The operator’s own wording, copied from the page linked below. Holding up your phone settles the question faster than explaining it.
This is one of Kinosaki’s public bathhouses, and the rule belongs to the town rather than to this particular building. The tourism association states in English that all seven allow tattoos of any size with nothing to cover — the only place on this site where a whole town is open rather than a property at a time. Two are shut as this is written: Satono-Yu indefinitely since April 2024, and Kono-Yu for renovation until 30 October 2026, leaving five. A day pass covering all of them is 1,500 yen, bought at any bathhouse, and guests staying in the town are normally given a pass at check-in instead.
There is nothing to do. Check in, go to the bath. No seal to buy, no measuring, no declaration to make, and no size at which it stops being allowed. If a member of staff does query it, the operator’s own wording is above — showing it ends the conversation without either of you needing the other’s language.
