Chalet Ivy Jozankei
シャレーアイビー定山渓
Chalet Ivy is the one operator in Jozankei that answers the question with a yes rather than a no. Its own Japanese FAQ says a tattoo that a single small seal can cover is fine in the shared baths, and that the seals are sold at the front desk. Anything larger than one seal, the hotel says, is for the hot spring bath in your room, which every room here has.
タトゥー・入れ墨がある場合も、大浴場には入れますか。 小さなシール1枚で隠れる大きさであればシールをご利用いただいたうえでお楽しみいただけます。フロントで販売しております。 シールのサイズを超える場合は、お部屋の温泉をお楽しみいただいております。
Best for: Buying a cover seal at the desk and getting into the shared bath the same afternoon
One seal is the limit the hotel sets, and it sells them. The shared bath is indoor plus outdoor with a sauna and no cold plunge, and the operator says the open-air bath is fenced for privacy so there is no view from it. Day use is not sold: the bath is for staying guests. The same company’s Niseko houses, Chalet Ivy Hirafu and Weiss Hanazono, answer the same question with a flat yes and no seal at all, so a tattooed traveler moving between the two sees the policy change.
