TOKYO (Reuters) - Japan's Princess Mako, the emperor's niece, on Tuesday married her college sweetheart, a commoner named Kei Komuro, by submitting documents to register her marriage, after a long engagement marked by intense media scrutiny and opposition.

The two, both 30, will move to New York, where Komuro works in a law office, although news reports say Mako will stay behind in Tokyo to make preparations, including applying for her first ever passport.
