If you mean how Japan has benefitted from a domestic market trade then they are actually reaping the benefits of it right now. Since the Japan tsunami destruction Japan has set a large budget ( around 29 trillion yen) for the rebuilding in the country. The govt. Has not issued any more bonds due their current large debt economy. Fortunately, Japan's debt is owed to it's own people as most of it was taken from the domestic Market so the situation is very different from Greece just in case you are wondering.
