From the notes by translator Yongdeok Cho: "This is an English rendition of Kane Kumagai’s Ainu language lessons, based on the lecture texts prepared for the Sapporo TV Radio Lessons in 2006. While I have not modified any of the example sentences, I had to change and edit various parts of the explanatory materials in order to make it useful to the English speakers. In terms of the use of the grammatical terms, I have largely followed the example of Kirsten Refsing’s The Ainu Language: The Morphology and Syntax of the Shizunai Dialect when appropriate."
