The KDDI Foundation has sponsored a charity concert every year since 2005. The earnings and contributions have been donated to fund the construction of elementary and junior high schools in various parts of Cambodia, at the pace of one school per year. This activity is carried out in cooperation with Japan Relief for Cambodia, an NGO with extensive experience in social support services in Cambodia.
At the donated schools, Internet connections are enabled using the telecommunications technologies of the KDDI Group. Special classes are offered in English and computer skills to help prepare the students for their roles as contributors to the future of Cambodia.
