Transportation
Hokkaido's only land link to the rest of Japan is the Seikan Tunnel. Most travelers to the island arrive by air: the main airport is New Chitose Airport at Chitose, just south of Sapporo. Tokyo-Chitose is in the top 10 of the world's busiest air routes, handling more than 40 widebody round trips on several airlines each day. One of the airlines, Air Do was named after Hokkaido. Hokkaido can also be reached by ferry from Sendai, Niigata and some other cities, with the ferries from Tokyo dealing only in cargo.
Within Hokkaido, there is a fairly well-developed railway network (see HokkaidÅ Railway Company), but many cities can only be accessed by road.
Hokkaido is home to one of Japan's three Melody Roads, which is made from grooves cut into the ground, which when driven over causes a tactile vibration and audible rumbling transmitted through the wheels into the car body.
