The 1952 bilateral air services agreement between Japan and the United States was considered particularly controversial, given that U.S. airlines designated to destinations in Asia-Pacific, west of Japan, were granted unlimited rights in fifth freedom. In the early 1990s, for example, the Japanese government`s refusal to allow flights on the New York City-Osaka-Sydney route sparked protests from U.S. management and airlines seeking proof of the route. The Japanese government responded that only about 10% of the traffic in the Japan-Australia sector was the third and fourth freedom traffic to and from the United States, while the bilateral agreement specified that the main justification for unlimited fifth freedom traffic was to fill aircraft carrying a large portion of U.S. or U.S. traffic under these rights. Japan had maintained many unused rights of the Fifth Freedom beyond the United States. However, due to the increased operating costs of Japanese airlines and geographic circumstances, they were considered less valuable than the fifth freedom enjoyed by U.S. carriers over Japan. Japan serves as a useful gateway to Asia for North American travellers. The United States asserted that Japan`s favourable geographical location and the transportation of its flag airlines, with a considerable volume of six transit traffic through gateway cities in Japan, had helped to improve the competitive conditions. In 1995, the air transport agreement was updated by liberalizing Japanese airlines` access to U.S.
destinations, while restrictions were imposed on U.S. carriers. :19-24 The third and fourth freedoms allow a fundamental international service between two countries. 146 Even if reciprocal rights are granted under the third and fourth freedoms, air services agreements (e.g. B Bermuda conventions) can still restrict many aspects of traffic, such as aircraft capacity, frequency of flights, airlines and airports to be served. :146-147 The third freedom is the right to transport passengers or goods from their own country to another. :31 The right to transport passengers or cargo from another country to one`s own country is the fourth freedom. :31 Third and fourth freedoms are almost always granted simultaneously in bilateral agreements between countries. The seventh and ninth unofficial freedoms are variations of the fifth freedom. It is the right to transport passengers or goods to foreign territories, without any travel in one`s own country, to or from their own country. :31 The seventh freedom is to provide international services between two foreign countries, and the ninth between the points of a single foreign country. One of the first AAS after World War II was the Bermuda Agreement, signed in 1946 by the United Kingdom and the United States.
The characteristics of this agreement have become models for the thousands of agreements that were to follow, although in recent decades some of the traditional clauses of these agreements have been amended (or “liberalized”) in accordance with the “open skies” policy of some governments, particularly the United States.  The fifth freedom of movement is sought by airlines wishing to use unserved or underserved routes or by airlines whose flights already make technical stops in one place, as permitted by the second freedom. :32 governments (z.B.
