The creators of "Sesame Street" are developing new content and materials to make the highly successful children's television program more useful for Japanese children learning English.

Aired on NHK for the past 30 years, "Sesame Street" has long been used by Japanese as a way to study English. In April of this year, the public television station introduced a new program called "Sesame Eigo World," developed specifically for teaching English as a foreign language.
