A 60-year-old woman who successfully gave birth in late July following fertilization treatment in the U.S. says she is ready to take on the challenge of raising her child, sources close to her said Tuesday.

She is believed to be the oldest woman to give birth in Japan.

"With childbirth, I made half of the journey," the woman reportedly said after the birth of her first child at a hospital in Tokyo. "I realize that the long road of child rearing will be a difficult one."
