I realize we are westerners for the most part, but it's true enough that the mainstream segments of many Asian cultures look down on tattoos and the people who get them. I know my parents did.
This article seems to suggest the same idea.

SEOUL — Wandering Seoul's streets in hopes of finding a tattoo parlor, even in the hippest neighborhood known to shelter hundreds of tattoo artists, is mostly a waste of time. You need to know the “proper” steps: first you run a search on the web, then you hook up with a tattooist who will guide you to a nondescript space, and finally you sit down for the illegal procedure.
Sitting in an underground tattoo parlor with his arms folded across his chest, 37-year-old tattooist Kang Un explains why things are so. There are no laws specifically about tattooing in South Korea, but medical laws state that only doctors can practice the act of penetrating someoneÂ’s skin with a needle.
In other words, to be a tattooist in Korea, you must hold a doctorÂ’s license.
Tattoos have long been considered in the country a mark of violence, membership to a gang, or at the least, defiance of mainstream culture. There wasnÂ’t much demand for a long time and getting a tattoo at an illegal parlor somehow suited the rebellious nature of it.
However, in recent years, many South Koreans have started to embrace tattoos as a work of art and a fashion statement. Tattooists are starting to call for regulation and legalization of the industry, but for now, most parlors remain illegal.
