Kong Vorn, a former journalist who survived the Khmer Rouge killing fields and later emigrated to Japan, runs the only school in Cambodia that provides Japanese language classes at the junior high and high school level.

Since 1999, the Cambodia-Japan Friendship Middle and High School that Vorn built in Prey Veng Province, 90 km outside Phnom Penh, has taught a large number of Japanese-speaking Cambodians.

Instruction is undertaken by volunteer teachers of Japanese whom Vorn has invited from Japan.
