The Japanese Soroban is the abacus that is still widely used today. One can perform addition, subtraction, multiplication, and division on the Soroban. The abacus is constructed of a rectangle frame with an upper and lower deck. Metal or bamboo rods run vertically and contain 1 bead on the upper deck and 4 beads on the lower deck. The upper bead, or heavenly bead, represents the value 5. The lower deck beads, earth beads, each represent 1. The columns of beads represent place value.
