Nojima Nami’s Okāsan! Gakkō de wa bōhan mo sex mo hinin mo oshiete kuremasen yo! (Mom! Schools Won’t Teach Your Kid About Sex, Contraception, or How to Stay Safe!) is a guide for parents who want to provide their children with the sex-ed that Japan’s schools do not.
Nojima refers to the private parts of the body as the “swimsuit zone.” She encourages teaching children about the parts of the body they should never allow others to see or touch. (Illustration by Ogura Naomi from Nojima’s book)
