Judo master on a mission to bring the Japanese martial art to Bali, Indonesia

75-year-old Japanese judo master Tsuneo Sengoku has coached about 100,000 people around the world since he started touring to promote the Japanese martial art in the late 1970s. A former policeman, he now runs a training centre on the Indonesian resort island of Bali, where he is training about 50 local people, mainly school pupils, for free.
