Rembrandt Resort Shiretoko
レンブラントリゾート知床
This is the one operator in Utoro that writes a way in. Its bath page carries a list headed with who may not bathe, and the tattoo line on that list is conditional: it bars people with tattoos who have not covered them with a tattoo sticker. Cover the work and you may use the seventh-floor baths. The hotel does not say what size of sticker it will accept and does not say it supplies them, so bring your own and bring enough. The rule reaches the day visitor too, because the same baths sell to non-guests in the evening.
入れ墨・タトゥーを入れている方で、タトゥーシールでタトゥーを隠されていない方
Best for: A tattooed traveler carrying their own cover stickers who wants a top-floor open-air bath over the Okhotsk Sea, with or without a room
Rebranded from 知床ノーブルホテル on 1 May 2026. Baths are on the seventh and top floor: a large indoor bath, an open-air bath on the high ground, and a sauna with self-service loyly. Guest hours 5:00–10:00 and 15:00–24:00. Day bathing 15:00–24:00, last reception 23:00, 2,500 yen for adults and 1,200 yen for children aged four through primary school, with 100 yen bathing tax on top for anyone thirteen or over. The spring is given as カルシウム・マグネシウム硫酸塩泉 / ナトリウム泉. The open-air bath closes in strong wind or thunder, and the hotel says it may cap numbers when the bath is busy. No private bath is listed.
