Mitsui Garden Hotel Sendai
三井ガーデンホテル仙台
Nothing needs covering. The eighteenth-floor bath page states that the hotel has abolished its admission restriction on body art and tattoos, the wording Mitsui Fudosan Hotel Management adopted across its bath-equipped properties. The same block on the page turns away only guests who are drunk. No size limit, no seal, nothing to declare at reception.
当ホテルではボディアート・タトゥ等の受入制限を撤廃しております。
Best for: A tattooed traveler who wants the rule in writing and a top-floor open-air tub in the middle of the city
Eighteenth floor, guests only, free, 05:00 to 09:00 and 15:00 to 25:00. There is an open-air section behind a lit wall the hotel describes as dappled sunlight. Not a hot spring: the page names no source and publishes no mineral analysis, so this is heated tap water in a business-hotel tower. Towels come from the guest room, and night wear and slippers are allowed in the corridor.
