すみません、タトゥーを隠すシールはフロントで買えますか？ — Excuse me, can I buy tattoo cover stickers here at the front desk? (Onsen · Sento, Formal — to staff, JLPT N4)

Gesture & etiquette

Gently tap the area on your body where the tattoo is located (e.g., your shoulder or upper arm) to show why you need the stickers.

Do not enter the bathing area with exposed tattoos if the facility clearly bans them, even if you plan to get a cover seal later.
