To enable students to communicate with Japanese, teaching Japanese as a foreign language must include all of the three areas-linguistic form, nonverbal expressions, and language behavior patterns.
The three areas are closely related with each other. It is essential to grasp them not by themselves but in relation with the others, and to clarify how any one of them can be used effectively with the others.
In making an actual teaching curriculum, efforts should be paid so that not any one of them should be disregarded, although the emphasis may differ depending on the student's conditions.
