This "Inspiration of Japan" concept was originally set to debut on February 20, 2010 with the delivery of its new Boeing 777-300ER prior to that date, followed by the introduction of the concept on that date on the Narita-New York route. However, due to delays to the new premium economy seats, the debut was pushed back to April 19. (The delay was due to the failure of a safety test in Japan of a new seat design axle, made by seat manufacturer Koito Industries Ltd. This safety test failure also affected deliveries of aircraft to be operated by three other fellow Star Alliance members - Singapore Airlines for its A380s, Thai Airways' A330s, and Continental Airlines for new 737-800 deliveries.[88][89])
