1. Concept 📱

New concentration game app aims to support learning Japanese for so called third culture kids growing up speaking a different language in kindergarten or school (👉 references & sources in research). The name of the app KoToKO (言と言) is a neologism that could mean Word & Word.

2. Problem 😦

• Difficulty of staying motivated to learn the Japanese language in non-Japanese speaking countries
• Frustration of not being properly understood in Japanese by their own families

3. Target group 🧒🏾🧒🏼🧒🏿🧒🏻🧒🏽

Children between 5-15 years old learning Japanese as (one of) their home language(s), as well as their parents who want to support the learning journey
