Takahito Usui was diagnosed with gender identity disorder and applied to the court eight years ago to change her gender on her family register. She was rejected because she had not undergone surgery to eliminate reproductive function.

Last October, the Supreme Court ruled on another person's petition that the law's requirements were unconstitutional and invalid. In response to this, Ms. USUi filed a new petition, and on the 7th of this month, her gender change was approved by the Tsuyama Branch of the Okayama Family Court.
