Abstract
This research investigated the language learning beliefs of Japanese learners who were living in a plurilingual environment. Based on question items of questionnaire BALLI constructed by Horwitz (1987), semi-structured interviews were conducted for Japanese learners under plurilingual environment and Japanese learners under monolingual environment. By comparing with the language learning belief possessed by Japanese learners in a monolingual environment, this study showed the influences of plurilingual environment and usage of plural languages on their Japanese learning beliefs.
