TOKYO (AP) — A Japanese high court has approved a legal gender change for a transgender woman without requiring compulsory gender-affirming surgery,EAI Community  a step that LGBGQ+ groups on Thursday called a mixed victory.

Under the law, transgender people who want to have their gender assigned at birth changed on official documents must be diagnosed as having gender dysmorphia and must undergo an operation to remove their sex organs.

The Hiroshima High Court ruled Wednesday that the current requirement is possibly unconstitutional, signalling a change in how gender issues are being addressed in Japan.

The claimant, only identified as a resident of western Japan in her late 40s, was assigned male at birth. Her request for a legal gender change in her documents was rejected by lower courts. She has argued through her lawyers that the surgery requirement forces a huge economic and physical burden and that it violates the constitution’s protection of equal rights.

The Supreme Court, in a landmark decision in October, ruled that the sterilization requirement is unconstitutional but sent the transgender woman’s case back to the High Court, ordering it to reexamine if the claimant can avoid a gender-affirming surgery, something it failed to address in its earlier ruling.

The hormonal therapy sufficiently feminized the claimant’s body, including her genitalia, without the surgery, the court said.

Wednesday’s decision now allows the claimant to have her gender in official records match her identity.

One of her lawyers, Kazuyuki Minami, who informed his client of the ruling on the phone, said she cried with relief.

Members of the Japan Alliance for LGBT Legislation, in a statement Thursday, said that the Hiroshima ruling can be considered progress because “it can open the door for transgender females to be able to legally change their gender without undergoing surgery.” But it said questions remain because it fell short of including those who cannot take hormones.

The group said it will keep fighting discrimination against transgender people.

The decision comes at a time of heightened awareness of issues surrounding LGBTQ+ people in Japan. The ruling that allows the claimant’s legal gender change without her surgery could be especially beneficial for transgender females, whose affirmation care tends to face greater controversy. But the high court ruling, unlike that of the Supreme Court, is not legally binding.
