Women-Only Car (女性専用車両 - Josei Sen'yō)
Specifically designated train carriages reserved for female passengers (along with young children and passengers with physical disabilities) during rush hour for safety and prevention of nuisance.
Widely standardized by major railway operators in the early 2000s to counter peak morning crowding hazards. These cars feature prominent pink markings on the platform edge and carriage windows.
Confirm with station personnel if a particular car lineup is designated as women-only at that hour.
