Since the size of Japan's economy is huge-it is three times bigger than China's-even a two to three per cent rate could provide enough growth momentum. I mean not only China, India but also Japan will be engine of growth, so to speak, for Asia and globally.
But as a matured economy, like the US or European nations, the Japanese economy cannot grow by five or six per cent.
Eight per cent growth is sustainable in the coming five years or more if infrastructure is improved and economic reforms are continued. The rate of growth can even be accelerated to 9-10 per cent.
