There are no user reports available, and there is no explicit information regarding tattoos on the official website of 滝野温泉 ぽかぽ. Therefore, it is unclear whether tattoos are allowed.
The rules state that individuals associated with organized crime, those related to them, people with tattoos, and intoxicated persons will be denied entry. Although there is no explicit mention of tattoos, the general tone suggests that tattooed individuals may also be refused entry. Given the lack of user reports, this assessment is based on an interpretation of the official statement.
User reports lean OK.
