How long does soroban take? From the first kyu levels to dan
Wondering how many years this will take? Here is a realistic timeline.
Japanese soroban grades count down from 10th kyu to 1st kyu, then up from 1st dan to 10th dan. With one weekly lesson plus ten minutes a day at home, a child who starts at 6 typically reaches 1st kyu in 4–6 years and 1st dan one to two years after that. 10th dan is passed by only a handful of people nationally each exam. With no home practice, roughly double every figure.
The ladder
| Stage | Grades | What the child can do |
|---|---|---|
| Beginner | (pre-10th kyu steps in many schools) 10th–8th kyu | Reads and places numbers; adds and subtracts 1- and 2-digit numbers with 5- and 10-complements; 2-digit addition of 5–8 terms |
| Elementary | 7th–4th kyu | Multiplication from about 9th kyu, division from about 7th; 3- and 4-digit addition of 10 terms |
| Advanced | 3rd–1st kyu | 5- and 6-digit addition of 10 terms; 4-digit × 3-digit; 2-digit mental sums of several terms |
| Dan | 1st–10th dan | 15-term addition of 5–8-digit numbers; large multiplication and division; 4–7-digit mental arithmetic; anzan of 15 terms |
In the Soroban Kingdom app, the ladder starts lower, at 20th kyu. 20th–11th kyu are small starter steps that come before the 10th kyu of the Japanese exams: 20th–16th kyu are 1-digit sums with no carrying, 15th–11th kyu bring in more terms and 2-digit numbers. Young children see a new level every few weeks instead of waiting months for the first exam grade. From 10th kyu up, the app follows the same shape as the exams. The full table is in the level guide.
Exact digits and terms differ between exam bodies (Nissho, Zenshuren, and others), but the shape of the ladder is the same. Zenshuren, one of the two main Japanese bodies, offers 37 steps from 15th kyu to 10th dan and holds lower-kyu exams monthly, so a child can pass something every one or two months.
Year by year (starting at age 6, weekly lesson + 10 minutes daily)
| Year | Typical grade |
|---|---|
| Year 1 | 10th–8th kyu |
| Year 2 | 7th–6th kyu |
| Year 3 | 5th–4th kyu |
| Year 4 | 3rd–2nd kyu |
| Years 5–6 | 2nd–1st kyu |
| Years 6–8 | 1st dan and up |
This matches the grade-by-school-year guide Japanese abacus schools use. Children who start at 9 or 10 move through the first two years' worth in about a year, then follow the same pace.
What slows children down
- No practice between lessons. The single biggest factor. Six days off erases the bead image; the first half of each lesson becomes revision.
- Two sticking points. The introduction of carrying (around 10th kyu) and the introduction of multiplication and division (around 9th–7th kyu). Both bring a new bead movement and a sudden rise in errors. Most drop-outs happen here.
- Chasing speed. Skipped 5-complements become a habit that has to be unlearned at 5th kyu.
- Big level jumps. Ladders with few steps leave children stuck for months with no visible progress.
What speeds them up
- Ten minutes daily, starting with yesterday's mistakes.
- A ladder with small steps, so something is passed every few weeks. Some apps subdivide the beginner range further; Soroban Kingdom, for instance, starts at "answers up to 5" and adds the 5-bead, then carrying, as separate levels before 15th kyu.
- Mistakes named by type (5-complement, carry, column shift, copying) rather than counted.
The conditions of good soroban learning, fine steps, visible mistakes, daily short practice and a ladder that leads to a real exam, are also the conditions for getting to dan.
Frequently asked questions
What is the difference between kyu and dan?
Kyu are the student grades, counting down: 10th kyu is the first, 1st kyu the highest. Dan are the expert grades above 1st kyu, counting up from 1st to 10th. Some bodies add "pre" grades (pre-1st dan, pre-3rd kyu) as extra steps.
Is 1st kyu a useful qualification?
In Japan, 3rd kyu and above from the main bodies is commonly listed on résumés; 1st kyu and dan grades are respected. Outside Japan the grade matters less than the skill, which is visible in seconds.
How long to 10th dan?
Most 10th-dan holders trained daily from early childhood for ten years or more, usually with competition experience. It is an elite level; 1st to 3rd dan is a realistic goal for a committed child.
You learn far faster by moving the beads than by reading. In Soroban Kingdom, levels 20–16 are free forever with no sign-up, on any phone or computer.
