A swarm of Micromachines capable of removing radiation from the environment found itself dubbed the Japanese or Asian Miracle (depending on who you ask). Japan was able to regain its status as a superpower after the implementation of the radiation dispersal removal method.
Japan is the only country with the technology to remove harmful radiation--a muscle they flexed during the last war and used at the end of World War III. There is a reference to an Asian Miracle. It is assumed this is the same thing and not a different use of same technology in a different arena. Japan hoped this would gain equal, if not superior footing with the American Empire.
