Japan -- A professor at Aichi University of Education, Ryo Uchida, has conducted research, showing that at least 110 children has been killed while practicing judo since 1983. Between 2009 and 2010, some 13 children have died, according to speroforum.com.
"Judo is an inspiring sport and very educative to one's mind," the professor said. "But schools must have a safety guideline."
Since Japan is scheduled to make the sport compulsory in schools as of 2012, it is reported that a number of parents are worried over these statistics.
One parent, Mr. Murakawa, who's 12-year-old son died following a judo class, said he had nothing against the martial art in itself, but a "military culture" imposed by some judo instructors, allowing punches and kicks as a way of teaching a rigid discipline to students. "The children - he said - for fear of being beaten must respect their coach, and never ask to rest".
