Japanese, "enjo kousai" : enjo = support : kousai = dating) in adolescent f
emales. The definition of "enjo kousai" is paid serial sexual behavior. Cur
rently in Japan. this is considered a deviant sexual behavior for adolescen
t females. Completed questionnaires from 600 randomly sampled high school g
irls were sorted into 3 groups: experienced, mildly resisting, and strongly
resisting. The findings were as follows : (1) young women's attitudes towa
rd amateur prostitution were influenced by; their friends' experiences with
that behavior;(2) engaging in amateur prostitution was strongly correlated
with delinquency; and (3) the group that had engaged in amateur prostituti
on expressed a strong desire to receive compliments from others or wanted t
o be viewed by others as outstanding. The results indicated that the adoles
cent girls who had engaged in amateur prostitution or those who had little
resistance to doing so showed the same factors as adolescent girls who were
sexually delinquent or sexually. active. The typical psychological charact
eristics of contemporary young people in Japan strongly relate to their att
itudes toward amateur prostitution.
