For students who want to learn foreign languages naturally and efficiently, we design language-learning resources by using language acquisition theory. For example, we create Spanish learning materials for students who want to keep learning Spanish on their own while they are unable to take the class at school. On the other hand, there is a Japanese guidebook about Kabuki for beginner level. This is designed as the Tokyo Olympics in 2020.
We also introduce an example of basic study based on language acquisition theory: what kind of difficulty do Japanese students have on acquiring Spanish phone "r," "l" and "rr"? Please come and see the world of the research and the material development of learning languages.
