Wherever Japan's imperials go, there too goes Fumiko Shirataki: in summer heat and winter cold, to the ocean and to the mountains.

Except when it snows or rains too hard.

"You can't get good pictures then — and if the camera lens gets wet, it might get damaged. I really worry about that," said Shirataki, 78, who has spent the last 26 years following and photographing Emperor Akihito, Empress Michiko and especially Crown Princess Masako.
