This paper focuses on children's centers from a viewpoint of teenagers. There are more than 4000 children's centers in Japan. We survey these centers whether or not they have special programs for teenagers, and how they are used by them. We picked up 4 centers, which have unique programs for teenagers, and conducted detailed case studies. As a result we have found these points. 1) The percentage of children's centers which have special programs for teenagers is very small, 10.9% in 1996 and 20.5% in 2001. However, increase in these five years is amazing. We can expect more percentage in the near future. 2) We have found great regional differences in establishment of children's centers and introduction of special programs for teenagers. In Tohoku area, there are many children's centers, but very few programs for teenagers. In Metropolitan and Kansai area, more centers have special programs for them. 3) The main visitors of children's centers are primary school pupils and their parents, although some centers offer programs for teenagers. Old centers, which were established earlier than 1996, have very few programs for teenagers. Programs for teenagers in children's center consist of special activity programs for them, priority time for them, and exclusive spaces for them. 4) We have found many variations of programs for teenagers. Presence of special stuff for them has big impact on actual activities and utilization.
