Life Secrets

Digital Children’s Book (App) for Children Sex Education

Self-Initiated Project


Digital Ehon Award

Winner 2019 | Digital children’s book award


In Japan no one wants to talk about sex education.

“Mom, where do I come from?” “Dad, why Mary doesn’t live with her parents?” Many children inevitably like asking these questions as early as the preschool years. It is a kid's nature to be curious about others who are different from their own, but these questions usually make their parents embarrassed and don’t know how to respond in an appropriate way.

Hopefully, Secret Life, a digital book drawn, written and designed with warmth and honesty, shows clear information for those children who are becoming aware of their bodies, but aren‘t ready to learn about sexual intercourse. It tells children life stories through three chapters, which are Parents Secret, Amazing Yourself and Love Is Love. After reading the whole book, children could acquire age-appropriate information about reproduction, birth, genders, self-protection and different types of family structure they may meet in kindergarten. It aims to educate and encourage children to treat someone in an equal way if he or she is different from their own, and also, make children could understand and respect other’s diversity and preference.

Chia-kuan Chen, Weijie Wang, and Yaohan Gu designed this didactic digital book in a light-hearted and playful ways so that parents will gladly share with young ones. The interesting interactions in Secret Life will attract children keep exploring by themselves or with parents and learning knowledge while playing.

Selling Point:

Have you ever considered talking about sex-related topic to your child when he or she asked you how was she born? Most likely not. Sex-related topics has always been a taboo in many different cultural contexts. Although it is widely acknowledged that adequate sexual education is vital to a child’s coming to adolescent, parents are still hesitant to talk about such topics. They are either worried about the likelihood to embarrass themselves with the “inappropriate contents”, or simply don’t know where to start.

To deal with this issue, we present “Life Secrets”, an interactive digital book which gives children the opportunity to explore sexuality. The stories in the book not only teach them to respect and protect their own sexual identity, but also touch on important issues such as sexual diversity and family structures. We want to empower our little readers to be aware of who they are, how they were born, and why differences aren’t necessarily bad.

Having done the user research in Japan, the UK and USA, we designed the book with the vision of making it universally effective. Adopting a human-centered approach in the design process, we focused on both parents’ experience of teaching their children with the book, as well as the children’s experience interacting with the book. With the cartoon-style motion graphics, the fun interactions, the intuitive narrations and the meaningful storyline, the book not only minimizes parents’ concern in the appropriateness of teaching children about sexuality, but also let children enjoy the process of learning it.


Age-appropriate sexual educational story

It’s Okay to Be Different

It inspires kids to celebrate their individuality through acceptance of others and self-confidence. It lets kids know that it’s okay to be a different color, come from a different place, be proud of yourself, and have different kinds of friends. It teaches them to not prejudge others, to tolerate difference and show respect for others and for themselves.

Augmented reality
