May 31, 2017 (Japan Today) - The lengthy, multi-syllabic nature of Japanese vocabulary means that words used in discussing social phenomena often evolve into abbreviated versions in order to streamline conversations. A prime example is "JK."
JK is the shortened version of joshikosei, which means "female high school student." After the schoolgirl pop culture boom picked up speed in the 1990s, JK became a commonly used shorthand in media headlines and online communication starting about a dozen years ago. Recently, it's been showing up in the term "JK business," which refers to the burgeoning industry in which businesses offer close, personalized customer service from high school girls to male patrons.
"Close, personalized customer service" might sound like a euphemism for sexual acts, but JK businesses don't offer such things, at least not officially. Instead, a customer might pay to have a girl sit and talk with him, one-on-one, in a semi-private setting, go for a walk through the city, or give him a massage. However, critics feel that the ostensibly chaste services provided by JK businesses, which are often provided in a manner that facilitates clandestine communication, have the potential to be a jumping-off point to prostitution and other illicit and illegal indecency in exchange for additional fees.
The industry even has its own jargon for such arrangements: ura opu, a truncated version of ura opushon or "secret options." Concerns about ura opu have led Tokyo to pass a municipal ordinance which will prohibit individuals under the age of 18 from working in JK businesses. The legislation is the first in Japan to target the JK industry by name, although similar provisions can be found elsewhere, such as in Aichi Prefecture's Ordinance of Juvenile Protection.
