The purpose of this study is to investigate the occurrence of intra-sentential and extra-sentential code-switching in interaction between a Japanese adult who has Hungarian ability and Hungarian children who are learning Japanese as a second language, from the view point of Japanese second language acquisition. The result shows that when the children's Japanese competence progressed, code-switching decreased. Depending on the situation, study and free conversation, different types of code-switching occurred.
