A number of airport options are available in Hokkaido depending on your ultimate destination.
Most flights from the Japanese mainland fly into New Chitose Airport in the southern part of the island. However, for access to some of the more remote regions, an alternative airport might be more appropriate for your plans.
New Chitose Airport
Traveling to and from New Chitose Airport is very easy. Take the JR Line trains from the airport to the major cities of Sapporo, Asahikawa, Hakodate, Obihiro, and Kushiro. A bus is a better option if you are traveling to the ski resorts of Niseko , Yubari and Rusutsu as fixed-route buses leave from the airport. For more freedom, rental cars and taxis are another travel option.
