TOKYO (AP) _ Nine years after a 9-year-old vanished from a schoolyard, the girl _ now a woman _ was found living with a man in a house she has not left since her disappearance, a news report said Friday.

The 19-year-old woman was hospitalized for exhaustion, Kyodo News agency said, citing police. She was discovered in a house in Niigata prefecture, 160 miles northwest of Tokyo.

According to Kyodo, the woman has not left the house's second floor since her disappearance.

Police refused to comment immediately on the report.

The report did not say whether the woman had been kidnapped and confined to the house or whether the man was being investigated. Neither of them was identified.

The woman, who was in fourth grade when she disappeared, had last been seen watching a baseball game at a schoolyard, the report said.
