A man under arrest for kidnapping and confining an 11-year-old girl in Kurashiki, Okayama Prefecture, had remodeled his home with an additional lock and soundproof walls to confine the girl for a long period, investigative sources said Monday.

With a well-meditated plan, Takeshi Fujiwara, 49, a self-described illustrator from the city of Okayama, wanted to "raise the girl as I wish," he was quoted as telling the investigators.

The girl, Sakura Moriyama, was found at Fujiwara's home late Saturday, taken to a hospital and was confirmed to have not been injured. Fujiwara was arrested at the scene. When investigators barged into the home Saturday night, he initially told them the girl was his wife, the investigators said.
