There are no user reports available, and there is no clear information from the official website. For the higaeri facility 天然温泉 御所の郷 located at 徳島県阿波市土成町吉田字梨木原1, it is unclear whether tattoos are allowed.
土柱ランド新温泉 appears to not allow guests with tattoos based on the explicit statement on their official website. However, since there is no detailed explanation or specific policy regarding this, we cannot be entirely certain.
