Starting next year, judo and other martial arts will be compulsory in schools across Japan.

The government says the programme will help preserve the country's national sport. But parents are worried.

In the past 30 years, at least 114 students have died and another 261 have been seriously injured while practising judo. According to experts, this is five times higher than any other major sport.
