"Parts of Japan gave them tattoo on the criminals´ arms. Many are simple lines around the arm. On the bottom line, the third left, I can see the sign of “悪”, bad in Japanese. This was Kishu´s (紀州/now Mie and Wakayama prefecture) tattoo."
Tattoos have a huge impact on the person getting one no doubt but also resonate with the ones who look at it. Part of the reason that people get tattoos whether they admit it or not is also to get the attention of others.
