Join us as we delve into the world of Japanese language proficiency among young children who have just turned six. In this podcast, we focus on the four key areas of language development: listening, speaking, reading, and writing. Using Kaechan, a six-year-old girl who has grown up surrounded by the Japanese language, as an example, we discuss the extent to which children raised in a Japanese-speaking environment acquire language skills. Through engaging case studies, we provide insights and anecdotes that will captivate Japanese language learners.
