Classes are conducted directly in Japanese and involve a variety of activities to help students learn the four skills of writing, reading, speaking, and listening in a balanced manner. Detailed guidance including individual supplementary instruction also helps students practically improve their weak points.

Tests are given twice for each level, and students are graded based on the results (pass or fail is determined in this way). According to their grades, students might be moved ahead a level or held back, and classes are put together each semester keeping student skill levels in consideration.

Students who are planning to take the Examination for Japanese University Admission for International Students can take advantage of preparatory classes in Science, Mathematics, and Japan and the World right before the test.

Extra kanji (Chinese characters) classes are available for students who are from countries where kanji is not used.
