Kei Komuro, the husband of former princess Mako, failed the New York bar exam, a source close to the matter said Saturday.

Komuro, who is planning to start a new life with the niece of Emperor Naruhito in New York as early as next month, is expected to retake the exam, possibly in February, according to the source.

Komuro's name was not found on the latest pass list released by the exam's organizer Friday, days after their marriage.
