TOKYO (AP) – Japan’s Crown Princess Masako, who disappeared from public view seven months ago, is suffering from a psychological disorder brought on by the pressures of royal life, the palace said Friday.

It has long been common knowledge in Japan that Masako was unhappy, but the statement from the Imperial Household Agency was the first medical explanation for her long absence from her official duties.

The agency said Masako has a stress-induced adjustment disorder and has experienced bouts of depression and anxiety. She is undergoing counseling and taking prescription drugs.
