The JK business is a form of commercial activity in Japan centered on providing simulated dating experiences with high school girls. The abbreviation JK stands for 女子高生, a female high school student. According to the definition used in statistics compiled by the National Police Agency, the term refers to businesses that offer customer service while employing advertising that explicitly states or implies that high school student are engaged in serving customers, using expressions such as "JK," "high school student," or "school uniform," regardless of whether actual high school girls are in fact involved in customer-facing roles. According to a survey conducted by Tokyo Metropolitan Assembly member Shun Otokita, as of 2017, cases in which individuals under the age of 18 or actual high school girls were engaged in JK businesses were rare.
