Japan stabbing spree: country's worst mass killings

At least 19 people died Tuesday 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 --
A 21-year-old man, Mutsuo Toi, goes on a killing spree, using a shotgun, Japanese sword, and an axe.
He kills 30 people, including his grandmother, before killing himself.
-- March 1995, Tokyo metro --
Members of the doomsday cult Aum Shinrikyo release sarin gas in the Tokyo subway system, killing 13 people and sickening thousands of commuters in Japan's most notorious attack.
-- September 1999, Shimonoseki Station --
A 35-year-old man, Yasuaki Uwabe, drives a car into the main train station in the southwestern city of Shimonoseki and then randomly stabs passers-by, killing five people and wounding 10.
