On the wall of a gray concrete apartment building on Kawasaki's Shinkawa-dori Avenue a colorful sign reads "Kincarn International Preschool."
Inside a second-floor apartment, Japanese children come up one after another and ask, in English, "How old are you?" "What's your name?" "Do you speak Japanese?"
Kincarn is one of some 20 international preschools in and around Tokyo. But unlike many other kindergartens designed for foreign children, Kincarn's class is mostly made up of Japanese children -- 40 out of 45 -- amid increasing interest among Japanese parents in an early English education.
