The headline refers to the ongoing cultural phenomenon in Japan characterized by the unprecedented influence and prominence of female figures in various facets of societal life. Emerging during Japan's Heisei era (1989–2019), the trend continues to gain momentum, strongly impacting television, pop culture, fashion, and workplace demographics. Despite the advent of the new Reiwa era in 2019, the “Heisei female boom” shows no signs of slowing down.

Japanese society traditionally holds conservative gender roles with men primarily in public and women in private spheres. The ongoing trend of rising female prominence represents a significant shift in societal norms. Measures to empower women, promote gender equality, and increase female workforce participation are also integral parts of Japanese government policies, dovetailing with social changes. The trend is widely celebrated as a step towards breaking gender inequality.

In the US and EU, women's empowerment and gender equality have been active social issues for decades, leading to significant advancements in many areas. However, the surge of the "Heisei female boom" in Japan showcases a somewhat unique cultural component as it corresponds with an era, reflecting the country's unique history and societal shifts.
