Junior and high school students often study English conversation to improve their chances at getting into a reputable college or university.
Parents are often eager to give their kids a head start in their English studies.
Kids as young as 4 years old are not an uncommon sight in some schools. They study English to maintain and expand their English speaking ability. Adults of many ages study English for as many and varied reasons as there are students. Some are businessmen looking to do business overseas, others want to learn English to improve their travel experiences overseas, some learn English as a hobby and even to improve their ability to sing at the karaoke bars still common and popular in Japan.
