Hoshino Resorts KAI Yufuin
星野リゾート 界 由布院
Hoshino Resorts is the only operator in Yufuin that answers the question in writing, and its answer is that it does not restrict guests with tattoos. It keeps a discretion clause: if staff judge that other guests may be frightened, they may refuse the onsen or large bath. The cover-seal condition in the same answer applies to properties open to non-guests, and KAI baths are for overnight guests only, so there is nothing here to buy or stick on. Read the group answer as a yes with a caveat rather than a guarantee.
私たちは、お客様の文化背景や価値観を尊重し、刺青・タトゥーをされているお客様の利用を制限しておりません。しかしながら、すべてのお客様が快適にお過ごしいただけるよう、他のお客様が恐怖心を抱く可能性があると私たちが判断した場合、温泉・大浴場のご利用をお断りする場合がございます。
Best for: A tattooed traveler who wants the shared open-air bath and an operator willing to put its position in writing
45 rooms. The same FAQ says the onsen and large baths at Hoshinoya, KAI and Risonare are for overnight guests only and cannot be used on a day trip, which is why the group’s cover-seal clause does not apply here. The discretion clause is the operator’s, not ours: it is the one sentence to weigh before booking.
