Financial markets may be cheering Japanese Prime Minister Naoto Kan's election, but his new role places some limitation on what he can do within Japan's parliament. Kan is known for a strong personality. But Robert Dujarric of TUJ says the office of the prime minister has limited power. "The prime minister of Japan is not the president of the United States, he's not the prime minister of the United Kingdom. The personality of the prime minister has less of an impact on policy."
