Why fly within Japan?
Japan's shinkansen is famous, but for long trips such as Tokyo to Hokkaido or Kyushu, a domestic flight is often faster, and for Okinawa and many smaller islands, flying is usually the most practical way. The figures on these pages come from data that Japan's Ministry of Land, Infrastructure, Transport and Tourism publishes about every major domestic airline, and they update automatically when new data is released.
Airlines fly different routes, and delays depend on season and route, so treat airline comparisons as a rough guide rather than a ranking.
