Shibu Onsen Kadoya
渋温泉 かどや
Does Shibu Onsen Kadoya allow tattoos? In a private bath
Kadoya’s spring comes up with dark flakes of mineral in it, and the inn says you will not find that water in any other bath in Shibu; its two private baths run on it.
Kadoya says nothing about tattoos. It keeps two private hot spring baths, a rock bath and a hinoki bath, taken by reservation only at the front desk, and that is where a tattooed guest should bathe. The large bath is shared.

How we know
Confirmed from official site, bath structure rather than a tattoo policy (the inn’s bath page)

Best for: A private soak in water with black mineral flakes that the inn says no other Shibu bath has
Two private baths, rock and hinoki, reservation only, booked at the front. The inn’s own source, free-flowing, runs hot and carries dark yu-no-hana flakes. Koishiya Ryokan nearby, which has no hot spring of its own, sends its guests to Kadoya’s private hinoki bath at 1,000 yen a person. Nine soto-yu keys lent at check-in; the inn gives soto-yu hours as 6:00 to 22:00. Kadoya’s operator also took over Tsukimi-no-yu Yamaichiya in July 2026.
