Tamaka Ogawa was about 10 years old when she was sexually assaulted for the first time. It was a public holiday and she was on the subway. A man standing behind her pulled down the band of her culottes and underwear, touched her bare bottom, then pressed himself against her. She recalls feeling shocked and physically sickened. When she reached home, she repeatedly washed the spot where he had pressed himself against her, although she was conscious of not spending too long in the toilet, in case her family noticed that something was wrong.
Some years later, on her first day of senior high school, she was groped on the commute home. After that, the groping and sexual assaults - men would often stick their hands inside her underwear - became a regular occurrence as she made her way to or from school in her uniform. Each time, she would run away, unsure of what to do.
