During the 11th century, the Chinese abacus, or suan pan, was invented. The suan pan is generally regarded as the earliest abacus with beads on rods. The Mandarin term suan pan means calculating plate. A suan pan has 2 beads above a middle divider called a beam (a.k.a. reckoning bar) and 5 beads below.
Use of the suan pan spread to Korea, and then to Japan during the latter part of the 15th century. The Japanese termed the abacus a soroban.Originally the soroban looked very much like its Chinese cousin having two beads above the reckoning bar and five beads below. Around 1850, it was modified to have only one bead above the reckoning bar while maintaining the five beads below. It was further changed by removing one lower bead in 1930. This one bead above and four beads below (1/4) arrangement remains as the present day Japanese soroban construction
