By Air
Planes connect all Japan's prefecture centers from over 90 airports for domestic and international airlines. Japan is reputed as a most travel-friendly country. Its major air companies are Japan Airlines (JAL), All Nippon Airlines (ANA) and Japan Air System (JAS).
However the 1986 air industry reform gave rise to many new local companies. Haneda Airport serves domestic lines from Tokyo while Limousine Bus vehicles run between the Haneda and Narita airports.
The Yokoso (Welcome)/Visit Japan Fare available only overseas gives visitors special domestic discounts (apart from the high season) to 42 cities served by JAL and its 2 subsidiaries - JAL Express in Itami Airport (Osaka) and Japan TransOcean Air in Naha (Okinawa).
Booking and ticketing are tied to a JAL international ticket and come before entering Japan. The Welcome to Japan Fare also offers cheaper domestic flights by JAL with the subsidiaries. This discounted fare however is not limited to JAL.
A similar Star Alliance Japan Airpass and Visit Japan Fare for overseas travelers are offered by All Nippon Airways.
