In short:

A court in Tokyo has found a law which bans women from voluntary sterilisation “lacks rationality" but is not unconstitutional.

The five female plaintiffs believe the ruling is a step forward for Japan, which has one of the world's strictest barriers to sterilisation.

What's next?

The judge presiding over the landmark case has called for active debate on the issue.
