It was the Christmas present nobody needed. On Dec. 25, 2019, Weekly Spa! magazine published a ranking of universities according to whether their female students were “sexually easy.”

“It’s not that I see just this article as a problem,” student Kazuna Yamamoto told The Japan Times at the time. “This caused all the frustrations I had about misogyny in Japan to explode.”

Yamamoto, along with three other women — two of them fellow students from International Christian University — channeled their frustrations into the formation of Voice Up Japan, a student-run organization that advocates for gender equality.
