The number of gun deaths in Japan totaled six in 2014, compared with 33,599 in the United States, according to GunPolicy.org, a website run by the University of Sydney.

While the U.S. is dealing with the aftermath of yet another deadly attack after Sunday night's mass shooting in Las Vegas, Japan remains one of the safest countries in the world in terms of gun-related incidents. The number of gun deaths in Japan was the second lowest among 34 OECD member countries after Iceland, while that of the U.S. topped the list, according to the website.

Thanks partly to Japan's ultra-strict gun-control laws, which ban possessing, carrying, selling or buying handguns or rifles, shooting incidents are rare in the country.
