Japan has some of the world's strictest gun control laws. As a result, the number of gun deaths each year in this country of about 126 million people are in the single figures.
I didn't realize how strict the laws were until I read about the 2020/21 Tokyo Olympics shooting events. Coaches are not allowed to touch the firearms, (not to mention fire one), only the participants. There are also strict limits on ammunition. Japan has a limit of 800 rounds of ammunition per shooter at any one time. This is less than other competitions and previous Olympics. There are designated contractors who are allowed to ship the ammunition into Japan specifically for the Olympic Games. A 16 page guide was created for teams to warn about Japan's regulations.
Wikipedia has compiled a list of gun laws by country if you are interested. This is what it says about Japan.
Japan The weapons law of Japan begins by stating "No one shall possess a firearm or firearms or a sword or swords", and very few exceptions are allowed. Citizens are permitted to possess firearms for hunting and sport shooting, but only after submitting to a lengthy licensing procedure. As part of the procedure, a shooting-range test must be passed with a "mark of at least 95%". A mental-health evaluation taking place at a hospital, and a thorough background check where one's family and friends are interviewed, are also part of the procedure. A gun license expires after three years, at which time license tests must be repeated. After ten years of shotgun ownership, a license-holder may apply to obtain a rifle.
Japan has been described as the country with "perhaps the first ever gun buyback initiative" in 1685, and is the first nation to have imposed gun laws in the world; as such, gun ownership is very rare: 0.6 guns per 100 people in 2007. In 2014, Japan saw 6 gun deaths.
Each prefecture in the country can operate a total of three gun shops. New cartridges can only be purchased after turning in expended cartridges. In turn, new magazines can be bought only by trading in old ones. If a gun owner dies, their relatives must surrender their firearms. Off-duty police are not allowed to carry weapons, and arrests are generally made without firearms; instead, police are expected to be proficient in judo.
Here is one Wikipedia illustration about handgun possession.
