Check policies beforehand if you have visible ink.

タトゥーがあっても入れますか？
Tatoo ga atte mo hairemasu ka?
Can I enter even if I have a tattoo?
More direct than a general check — useful when you already know you have visible ink. Many public onsen still ban tattoos due to their old association with the yakuza, though this is slowly changing, especially in tourist areas.
タトゥーを隠すシールはありますか？
Tatoo wo kakusu shiiru wa arimasu ka?
Do you have stickers to cover tattoos?
Many tattoo-friendly onsen and sento sell or lend cover-up patches (シール/パッチ) at the front desk for guests with small tattoos.
貸切風呂はありますか？
Kashikiri-buro wa arimasu ka?
Do you have a private bath?
貸切風呂 (kashikiri-buro) = a private/reservable bath, often booked by the hour — the easiest workaround if a facility doesn't allow visible tattoos in the shared baths.
