U15 refers to girls under the age of 15 and is a Japanese pedophile code for this kind of filth. Nowadays it mainly refers to underage girls posing in bikini, bathing suit or underwear. Before 1999 however, there was no law against child pornography in Japan and booklets and magazines where freely available in bookstores and kiosks all around the country.
