“The man tried to move her over toward the door, but she did not move,” the driver said, according to the transcript. “So he got off first and put his bags on the ground, and he slid his shoulder under her arm and tried to pull her out of the car. It looked to me like she was unable to walk on her own.”

Ms. Ito also appears incapacitated in hotel security camera footage obtained by the police. In pictures from the footage seen by The New York Times, Mr. Yamaguchi is propping her up as they move through the lobby around 11:20 p.m.

Ms. Ito said it was about 5 a.m. when she woke up. She said she wriggled out from under Mr. Yamaguchi and ran to the bathroom. When she came out, she said, “he tried to push me down to the bed and he’s a man and he was quite strong and he pushed me down and I yelled at him.”

She said she demanded to know what had happened and whether he had used a condom. He told her to calm down, she said, and offered to buy her a morning-after pill.

Instead, she got dressed and fled the hotel.

Ms. Ito believes she was drugged, she said, but there is no evidence to support her suspicion.

Mr. Yamaguchi said she had simply drunk too much. “At the restaurant, she drank so quickly, and in fact I asked her, ‘Are you all right?’” he said. “But she said, ‘I’m quite strong and I’m thirsty.’”
