Amid heavy security Wednesday, the media, Imperial enthusiasts and well-wishers swarmed to prestigious Aiiku Hospital in Minato Ward, Tokyo, during the wee hours to wait for Princess Kiko to give birth.

Expectant mother Asami Yamamoto, 27, said she was happy to hear that the royal baby was born in the same hospital where she is scheduled to give birth to a girl in October.

"It will be a nice memory I can tell (my child)," she said.
