“Quietly, Japan has established itself as a power in the aerospace industry, with a long history and considerable ambition. Only three countries reached orbit before Japan did nearly half a century ago. Today, with questions about the reliability of relations with the United States (which some here view as a fading force) and worries about North Korea, the country is taking steps to bolster its presence in space with key military assets. Within a few years, Japan intends to have its own GPS system and a network of military satellites.”
