Time Out says
Much like tattooed folk in Japan are expected to cover up, otaku are often urged to hide their obsession with anime and manga from the public eye. So it’s no wonder that animated character-themed tattoos are gaining in popularity. Known as ‘o-tattoo’, this new genre was pioneered by Aki, the owner of Diablo Art who publicly admits to being an otaku – even his studio is full of character figurines. Any professional horishi can recreate an image on the skin, but the intricate details and personalities of specific fictional characters can only be understood by someone familiar with the anime and manga subculture. Aki, who says he has several anime geeks as customers, talks through the specifics with every single hopeful, ensuring your o-tattoo is exactly as you imagined it.
