Duty-free goods are products that you buy at the price they are when they are imported into the country, before duties or consumption tax are added. A lot of the goods sold in duty-free shops are sold in the state they would be before being imported into Japan, so no duties have been applied to them yet. Since you will take them back out of the country again after you buy them, you can buy them at their duty-free price.

Reasons why duty-free goods are cheap. They are cheap because they are not subject to duties, alcohol tax or other levies when they are imported, and on top of that, they don't carry consumption tax. Locations such as the areas you reach after you pass through passport control at the airport, on board flights on international routes, and on board ships sailing in international waters, and other locations where duty-free goods are sold are all treated has being "outside the country." When goods enter the country, they are deemed to be "imported" and are subject to taxation; however when the goods are in these kinds of places (i.e., places "outside the country") then, technically speaking, they haven't been imported and can therefore be sold in duty-free shops at prices that don't include any taxes. Since these goods are not "within Japan" they aren't subject to Japanese consumption tax, either.
Normally, when goods like alcohol, tobacco and perfume are imported, they are subject to quite a lot of taxes. This is why you can buy them duty-free at much lower prices than you can buy them anywhere else in Japan.

Generally, "duty free" means that duty has not been levied on the item. On the other hand, "tax free" means that consumption tax and other value-added taxes have not been added.

The scope of duty-free categories will differ, from one country to the next. Even if you have bought something duty-free, please be aware that you may be charged for local duties if it falls outside the duty-free categories in the country you are taking it to. Moreover, when bringing items into Japan on your return, please be aware that Japanese duty categories will apply. You can learn more about overseas duty-free categories by reading the travel schedules given to you by your travel agency, or reading other pamphlets or guide books, or by visiting the homepages of the embassies of various countries.
To find out more about Japanese duty categories that will apply when you return, please check with  Narita Branch Customs.
