Well I had an idea and I would like you all to think it over
I think we should have an option in the Tattoo place that can allow us to remove the tattoo. Before you reject this idea based on the time period it is set in, remember that the Naruto universe does have many advances in technology so you could have laser removal or if you feel that that is too advanced than there are other methods of removing tattoos.
I'm sure those methods would obviously be extremely painful with such things as removing the skin. Also this option wouldn't be free and you would have to pay to get a tattoo removed. Just like getting a tattoo, the pain can last several days.
There are those people who regret certain tattoos and I think it would be a great thing to consider.
