In order to set the scene for this volume, I begin the chapter with a narrative of my experience on the day when I got promoted to a professor at a Japanese university by combining my professional experience to the ideologies of native-speakerism and trans-speakerism. I also include the overall background of the study through providing the aims of the research, explicating the significance of the current inquiry, and outlining the core ideas of this book: native-speakerism and trans-speakerism. In other words, this chapter delineates how these two influential ideologies in language education come together in this book and makes a case for why the present inquiry is a fertile endeavor to make. The chapter concludes with a brief description of the structure and content of the volume.
