Japan's Supreme Court has declared in a landmark ruling that the restrictions imposed by a government ministry on a transgender female employee's use of restrooms at her workplace are illegal. Landmark decision: In a unanimous verdict on Tuesday, the judges deemed the Economy and Trade Ministry's limitations on restroom use for the transgender official as "extremely inappropriate." The unnamed ministry employee, who is reportedly in her 50s, filed a suit in 2015 after she was banned by her government office from using the women's restrooms on their floor.
