Leaving New Zealand If you take a firearm from New Zealand to return, you will need an export permit issued by MFAT, an import permit issued by the police and an export certificate issued by the customs authority. Show these forms when you return to prove that the firearm was taken in New Zealand and not obtained abroad. You can obtain the certificate at any customs office a few days before departure or at the departure airport. Take enough time for formalities when you get the certificate at the airport. If you do not have a permit to import the firearm into your destination country, you risk your firearm expiring. Contact the appropriate embassy to review its gun laws. Although they are also considered « soft air forces », air guns are strictly prohibited in all states except the Northern Territory (where they are considered ordinary air guns and subject to appropriate laws and licenses) and the ACT (where they are considered « counterfeit firearms »). Along with state laws, local county laws or ordinances may be relevant to air gun users. In general, state laws do not mention Air Force laws, but local counties do. In Japan, gun laws are quite strict. A Japanese civilian can apply for a license to own an air rifle, a low-powered weapon powered by carbon dioxide rather than gunpowder. The licensing process is not easy, and the possession of air guns is becoming increasingly rare, in part because of the difficulty of going through the licensing process.
 The process takes a long time, and if you want to own an air gun, you must take courses organized by the Prefecture`s Public Safety Commission.  An applicant must be at least 18 years of age.  This is a list of air rifle laws by country. Most countries have laws on air guns, but these vary widely. Often, each administration has its own unique definition of an air rifle; And regulations can vary for weapons with different bores, energy or muzzle velocity, or ammunition, with weapons designed to fire metal pellets often being more tightly controlled than airsoft weapons. There may be a minimum age for possession, and the sale of air rifles and ammunition may be restricted. Some parts of the world require permits and background checks similar to those required for the firearms themselves. Air forces that meet the definition of a firearm in the Penal Code, but are not considered firearms for certain purposes under the Firearms Act and the Criminal Code, are those that have a muzzle velocity of less than 152.4 metres per second (500 feet per second) and/or a maximum muzzle energy of 5.7 joules (4.2 feet of pounds). These air rifles are exempt from the licensing, registration and other requirements of the Firearms Act, as well as the penalties in the Criminal Code for possession of a firearm without a valid licence or registration certificate. However, they are considered firearms under the Criminal Code if they are used to commit a crime. Replicas of low-speed air rifles (less than 366 feet per second), designed to look almost accurately like a firearm, are considered a prohibited device and are not approved for possession or purchase.
Under the new Bill C-21, medium-speed air rifles (366 to 500 feet per second) designed to look almost exactly like a firearm will also be banned. The mere possession, acquisition and use of these air guns for lawful purposes is also governed by provincial and municipal laws and statutes. For example, some provinces may have set a minimum age for the acquisition of such an air rifle. These air rifles are exempt from the specific storage, transportation and handling safety requirements set out in the regulations supporting the Firearms Act. However, the Criminal Code requires that reasonable precautions be taken to use, transport, handle, store, transport and ship them safely.  Air guns that generate more than 6 ft·lbf (8.1 J) and air guns that generate more than 12 ft·lbf (16.2 J) of muzzle energy are legally referred to as « particularly dangerous firearms ».  Therefore, possession of these air rifles requires possession of a Firearms Certificate (CBA); However, the possession of such air pistols is prohibited as they are defined as « prohibited weapons » under section 5 of the Firearms Act 1968. (Article 5 authority is normally granted only to members of the arms trade.) « Immediate monitoring » means that the licensed person or an elderly person is within reach and under the control of the person using the air rifle.
