Arriving in Tokyo late Monday evening, Biden was met on the tarmac by Caroline Kennedy, the new U.S. ambassador to Japan. He started his morning Tuesday by having coffee with Irish Prime Minister Enda Kenny, who is staying in the same hotel as the vice president. Later Tuesday, Biden will meet with Prime Minister Shinzo Abe. He'll also tour a technology company and highlight the role of women in Japan's economy. The trip comes as many in Asia are questioning whether the U.S. will follow through with President Barack Obama's pledge to rebalance the U.S. foreign policy focus toward Asia. "Yes, some question our staying power," Biden said in an interview with Japan's Asahi Shimbun newspaper. But Japan knows that we have stayed for more than 60 years, providing the security that made possible the region's economic miracle. Economically, diplomatically, militarily, we have been, we are, and we will remain a resident Pacific power. Later in the week, Biden will meet in China with President Xi Jinping amid an international spat over China's new air defense zone. Biden will wrap up the trip in Seoul, where he will meet with South Korea's president and prime minister.
