The accessories in question fall into four functional groups: those that provide structure, those that provide compression, those that provide friction, and those that provide decoration. The first group, structure, is dominated by the obi-ita (the stiffened board inserted behind the obi) and its variants, such as the hakoseko for cushioning. The second group, compression, includes the obi-age (the soft silk scarf tied over the top edge of the obi) and the obi-jime (the decorative cord that cinches the entire assembly).
