The legislation calls for relocating some central government operations and offering tax incentives to help develop another major economic centre capable of competing with the Tokyo metropolitan area. Osaka has emerged as the leading candidate, although the city continues to lose companies to Tokyo, highlighting how difficult it may be to build a genuine alternative to the capital. Osaka Prefecture has Japan's second-largest economy after Tokyo, with a nominal gross domestic product of 43.12 trillion yen (US$266 billion) in fiscal 2022. It is home to Kansai International Airport and is a key stop on the Shinkansen network linking Tokyo with western and southern Japan.
