Mr. Hatoyama has some ambitious plans for Japan according to this New York Times article. Some goals seem realistic but others seem to me, as well as various analysts, to be completely unrealistic.
Some of his goals that I think are doable include turning Haneda into a 24-hour international airport and expanding the economy at an average rate of 2% over the next 10 years. The goal for expanding the economy seems doable to me based solely on his meager projection of 2% average per year. Compare that to China's average of 8 to 10% growth per year.
Some of Mr. Hatoyama's other goals seem completely unrealistic pie-in-the-sky goals such as creating an Asian free-trade zone which I assume would include China and tripling the number of foreign visitors to Japan to 25 million. I don't think it will be possible for China and Japan to agree on a free-trade zone, at least by 2020. I also don't see how it's possible to achieve the 25 million foreign visitors goal but maybe since he has given 10 years to accomplish it. Good luck.
