Japan's child poverty rate has improved amid a steady economic recovery, but experts say continuing support is vital to prevent social exclusion.

A Tokyo-based nonprofit organization called Kid's Door offers free education to children from single-parent families or those on welfare that are living in relative poverty and often forced to drop out of high school or college due to financial difficulties.

Kid's Door volunteers teach students — in a range from elementary through high school — who cannot afford supplemental tutoring, mainly in Tokyo.
