Antique Japanese Soroban Abacus – Osaka Wholesaler, Hiroshima Marked

Antique Japanese Soroban Abacus – Osaka Wholesaler, Hiroshima Marked

Authentic traditional Japanese soroban abacus featuring a solid wooden frame, wooden bi-conical beads, and metal rods. This is a substantial, heavy example intended for professional or commercial use rather than a student model.

The reverse panel bears hand-painted Japanese kanji reading “Osaka Wholesaler” (大坂問屋) and “Hiroshima” (廣島), indicating commercial distribution through an Osaka trading house with regional ties to Hiroshima. These markings are consistent with Japanese merchant tools produced for business or accounting use.

Crafted with traditional joinery and dense hardwood materials, the abacus shows smooth bead movement and excellent structural integrity. The natural patina and surface wear reflect authentic long-term use and age.
