Opposite the kamiza is the shimoza, or "lower seat," the meeting place for all students.

During official ceremonies and instructional periods, students are assembled in ranks along this side.

When facing the kamiza, the side of the dojo to the right is called joseki, or "upper side" on the left is the shimoseki, or "lower side." When instructed, students line up along the shimoseki, while instructors face them from the joseki.
