This study set out to examine current teaching materials for Japanese and investigate whether their composition and presentation methods for “wakeda” would be proper to promote their right understanding among Korean learners of Japanese. Even though it was an examination within a limited scope, its findings point out that the study materials were so far from enough that the accurate understanding and acquisition of “wakeda” would be impossible. Korean learners of Japanese need to understand the meanings and uses of “wakeda” in an accurate manner to use them with ease. The present study defined the meanings of “wakeda” and provided its typical examples, proposing learning methods based on “wakeda”. Most Korean learners of Japanese have a difficult time with the modality form, one of the grammar areas that pose a challenge to them. The present study conducted field analysis of “wakeda” sentences considered to have a very high difficulty level and emphasized once more the need for education on “wakeda”.
