A wooden board used during practice or mōshiawase in place of the taiko, kotsuzumi, and ōtsuzumi. The hariban is often made with a harder wood such as Japanese zelkova; the outside is cube-shaped, and the inside is square. The hariban is placed in front of the knees while the player is in a seated position, and is often played with a hari-ōgi, a hand fan folded in half with Japanese paper covering it. The taiko is used in the mōshiawase and for the kotsuzumi and ōtsuzumi, the actual instruments are often used. The hariban is also known as the hyōshiban.
