Banshu (Harima Province), Katayama-made, One-Touch Soroban (Abacus) - 23 digits. In the current abacus industry, it seems that those other than high-end products are made in Banshu, even in Unshu. Because of this, it's hard to say which is better for mid-range abacuses. This item can be said to be a suitable one for those using a one-touch white bead abacus for the first time. Thank you for viewing.
