Domestic air travel is both cost and time efficient, and is one of the best ways to explore several destinations in Japan during your trip.
With some 90 airports serving domestic and overseas flights, air travel within Japan is very convenient. The two main airline carriers offer cheap domestic flights for visitors to the country. Look into the Visit Japan Fare/Welcome to Japan Fare by Japan Airlines (JAL) and the ANA Experience Japan Fare by All Nippon Airways (ANA) to find out more.
You are not just limited to the two major carriers, though, as a whole host of low-cost carrier airlines (LLCs) have entered the highly competitive domestic travel market. These carriers service airports throughout the country, from frozen Hokkaido in the north to subtropical Okinawa in the south. Research the flights from Jetstar Japan , Peach , Skymark Airlines , and Vanilla Air for the options most appropriate for you. As is the nature of low-cost air travel, some of the most convenient services provided by larger carriers—such as online check-in—are not always an option, and restrictions are placed upon the amount of luggage you can take without incurring extra cost. Research thoroughly before booking your tickets.
While generally a reliable way to travel, flights can be delayed by typhoons and even volcanic activity—especially if traveling down to the Kagoshima area. Check the individual companies' websites for cancellation policies.
