"The time has come that Japanese themselves acknowledge their ownership to the excellent culture and spread it around the world. It is the responsibility of the Japanese to educate good Japanese teachers. The textbook is well-equipped to support such missions."
"The textbook is full-scale Japanese teachers' training book."
"There are two types of method in teaching Japanese language. One is 'Direct method' to teach Japanese by Japanese language, and the other, 'Indirect method' with another medium (English). The Pana-lingua's quick learning method is the latter, but the grammatical structure and concept are clear and concise…helps us visualize and construct the realistic image. I believe this is an effective tool to learn foreign language."
"… I consider the elements of the Western scientific approach is essential to help the English speaker's learning…the author is carefully selecting the topic so that the learners will enjoy the Japanese culture and language."
