When I already read the details about this news, I really surprised that why the Japanese PM resigned the PM. After that, I found that the reason why Hatoyama resigned this position. The prime minister Yukio Hatoyama resigned from being prime minister position for eight months because he was making the wrong determination about an agreement between Japan and US. He made a decision not to move the U.S. Marine air base out from the Okinawa island, but moved to other part in the island instead because he was honest to the words that gave to the US's government. He finally was in trouble, so he quited. The problem after Hatoyama left was to find a new prime minister, and a new PM who have been expected from Japanese people is Naoto Kan. Furthermore, if the next PM was elected, it was quite strange because it would be five prime ministers in four years.
In my opinion, I think that he's a good quality to be a prime minister of Japan. In contrast, I quite know that a mistake be happen every time. It is good to have a strong leader of the country. It seems like a country is strong. The best thing is to elect the prime minister as soon as possible before the country gets worse. However, I quite think that it was a great responsibility that Hatoyama decided to quit because he made an unpleasant and wrong decision for his Japanese people.
