Unfortunately, there are no special tattoo aftercare cream brands you can easily get in Japan. If you plan to get a tattoo in Japan, you can bring Bepanthen or Aquaphor with you. If you don’t have anything with you, there is one product that can be used to keep your new tattoo moisturized. You can sometimes find it in Family Mart or any drugstore. It costs only around 400 yen!
