Before hosting the 1964 Summer Olympic Games, Tokyo carried out an unprecedented upgrade of its transportation system that gave the capital a bullet train system, elevated highways and a monorail connecting the city with Haneda airport.
Giving a similar boost to the infrastructure before the 2020 Games may be tricky, as the metropolis today has little space available for major new infrastructure projects. But a new subway line and an expansion of Haneda airport are some of the projects being pitched for development over the next seven years.
Touching on how preparations for the Olympics alone will have a positive influence on the economy, Chief Cabinet Secretary Yoshihide Suga has said that "efforts to end deflation will gain a big momentum."
