Josei is actually a demographic but is also considered a general category in anime. It specifically targets female viewers around the age range of 18-40. These shows depict life and romance in a more mature light, usually with more grounded realism and less idealistic fantasies. The subgenre is fairly wide and doesn't necessarily have to focus on romance. It merely needs a narrative that caters to the mature woman. Josei originated from manga during the 80s. Girls who grew up reading shoujo stories from previous decades wanted stories for adults.
