Saturday's wedding of Britain's Prince Harry and Meghan Markle represents a sign of shifting royal traditions, given the bride's unprecedented profile: The former actress is American, biracial and once divorced.

In Japan, the royal wedding is a hot topic treated as a cause for celebration on entertainment shows and in newspapers.

However, many in the nation have probably not seriously discussed the various issues Markle faced ahead of the ceremony at St. George's Chapel at Windsor Castle, west of London.
