Daruma-Marked Japanese Wooden Abacus – 15 Columns, Five-Bead Configuration Item Description: A Japanese soroban with a rectangular wooden frame and 15 columns, each containing one upper bead and five lower beads. This five-bead configuration represents an older style of Japanese abacus, differing from the four-lower-bead arrangement commonly used today. The brown wooden beads have a distinctive angular profile, forming rhythmic rows within the frame. A dark horizontal reckoning bar contrasts with the lighter wood and carries Japanese characters denoting numerical positions. The combination of geometric beads, visible wood grain and marked divisions gives this practical calculating instrument a distinctive visual character. One short side bears the Japanese inscription “ダルマ算盤” (Daruma Soroban), meaning “Daruma Abacus,” together with a Daruma figure mark. The wooden back panel also carries handwritten lettering. These details add individual character to this traditional calculating instrument. An interesting piece for a collection of calculating instruments or Japanese everyday objects. Brand / Mark: Marked “ダルマ算盤” (Daruma Soroban), with a Daruma figure emblem.
