TOKYO (AFP) - At least 19 people died Tuesday (July 26) when a knife-wielding man went on the rampage at a Japanese care centre for the mentally disabled, the country's worst mass killing in decades.
Satoshi Uematsu, a 26-year-old former employee at the facility, turned himself in to police over the early morning attack, reportedly saying: "The disabled should all disappear."
Japan has one of the lowest rates of violent crime in the developed world and extremely strict gun laws. When mass killings have occurred, they typically involve knives.
Following are some of the worst mass killings in Japan:
May 1938, rural Okayama

There have also been cases of family members killing ailing and ageing spouses or parents suffering from dementia in Japan's rapidly ageing society.
