Ruling comes months after supreme court ruled that requiring sterilisation before a change of gender in official records was unconstitutional

A court in western Japan has approved a transgender man’s request to have his gender changed in official records without undergoing sterilisation surgery, the first known ruling of its kind since the country’s top court struck down a surgery requirement for such record changes.

Tacaquito Usui, 50, could get the gender listed for him in his family registry updated to male, the Okayama family court’s Tsuyama branch ruled on Wednesday. Usui’s original application for the revision was rejected five years ago.
