Many Korean scholars have mixed feelings in relation to documents which prove that literature and an original writing system had been widely established in Japan including for people outside the aristocracy much earlier than in Korea; therefore, some Korean scholars may prefer to adhere to hypothesis of direct relationship between 'the ancient Korean language' and the "Manyoshu" without concrete scientific evidence to back up the assertion.
多くの韓国人学者は、庶民も含む広範な文学の成立と固有言語の表記法が、自国よりもはるか以前の時期に日本において文献で確認できることに複雑な感情を抱いており、「古代朝鮮語」と『万葉集』の直結的関連性については、韓国の学界では科学的論証を経ずに肯定的に捉えられている。
