TOKYO – Japan's Crown Princess Masako has left for her first official overseas trip since she became ill a decade ago.

Masako left Sunday to accompany her husband, Crown Prince Naruhito, on a six-day trip to the Netherlands, where they will attend Tuesday's coronation of Crown Prince Willem-Alexander as the new Dutch king. Officials say Masako may skip other events depending on her condition.

It is Masako's first official overseas trip since the couple's 2002 visit to New Zealand and Australia.

Masako developed a stress-induced illness soon after giving birth to the couple's only daughter, Aiko, who is now 11.

Palace doctors say the U.S.-educated Masako is getting better, but she hardly appears in public.
