Japan's maestro Seiji Ozawa attends a news conference in Tokyo December 19, 2013. Ozawa, one of the world's most famous music conductors, said on Thursday he intended to keep going for years to come, despite frustration that recent ill-health has prevented him from being as active as he used to be. Ozawa, 78, was diagnosed with esophageal cancer in January 2010, which was followed by lower back surgery in January 2011, and has since concentrated his activities in Japan.
