Japan does not like guns

In 2008 we had over 12,000 gun-related killings, Japan had 11.  Perhaps, it's because it takes a fair amount of effort to get a gun there.  First, go to this month's all-day class and pass the test.  Go to the shooting range and pass another test.  Go to hospital for a mental test and a drug test.  Finally, pass a rigorous background check for any criminal record or association with criminal or extremist groups, and you will be the proud new owner of your shotgun or air rifle. However, you must tell the police where you store your gun and its ammunition. The police will visit you every year to inspect the gun.  And every three years you will re-take the test.
