Empress Michiko has canceled a visit to an Imperial villa in Hayama, Kanagawa Prefecture, after feeling faint, the Imperial Household Agency said Sunday.

She had been scheduled to visit Hayama with Emperor Akihito from Monday to Friday, according to the agency.

She has experienced bouts of faintness since the end of October, but regular checkups late last month showed no major health problems, it said. The agency added she is expected to resume her regular duties from the middle of this month.
