I interviewed volunteer 'Japanese as a second language' teachers in Ehime prefecture and observed their lessons to find out how the dialect is treated in their classes. As a result, this study revealed that the teachers thought it is not good to teach using dialects in their lessons. They also want to follow standard accent and intonation. However, it was found that the number of learners who want to study the dialect is higher than their expectation. Therefore, I will propose the development of a website, which is constructed mutually by learners and teachers.
