This abacus is in very good condition and works perfectly. You can see the hand-engraved Japanese numbering on the first and last six positions of the dividing bar.

The metal sticks, which are attached to the top and bottom of the frame and run vertically across the divider bar, are called rods and are used to move the balls. Each rod represents one of the digits in the number. To carry out the calculation, you need to choose a rod as the number of units. Counting from this rod to the left, you count the tens, hundreds, thousands, tens of thousands... and to the right of the number, the tenths, hundredths and so on. Abacuses generally have 9 to 15 rods. Students of finance and accounting prefer to use a special abacus with 13 or 17 rods.

In terms of value, an upper ball represents five units and a lower ball represents one unit.
