Japan seeks a Substitute for F-22

December 3, 2009: Japan has grounded all of its F-15J fighters until
it can figure out what exactly caused one of its F-15s to shed several
parts during a recent air show. Seven pieces fell off the aircraft as
it made a sharp turn..

This sort of thing makes Japan even more eager to find a modern
fighter to replace its 118 F-4 and 202 F-15 aircraft. With China and
Russia putting more new fighters into service, Japan sees a threat.
Japan has made several efforts to buy the U.S. F-22, without success.
