## What is Soroban?

[Supervised by Satsuki Abacus Dojo] Learn the abacus (soroban) with video.

Learn the soroban under the supervision of Satsuki Abacus Dojo, an active abacus school in Osaka, Japan — a member of the Japan Abacus Federation with a proven record, including perfect-score wins at the Kinki Regional Soroban Championship (1st in Kinki) and the 2024 "Osaka No.1 Soroban" tournament. Real teaching know-how is built into the app.

From children touching a soroban for the first time to advanced learners mastering mental math and flash anzan — watch every bead movement in the video lessons and build calculation skills from the ground up. Great before a soroban class, for review alongside class, or for learning the abacus at home.

■ What you can achieve
- Do mental math: calculate numbers quickly in your head with soroban-style mental math and flash anzan.
- Calculate faster and more accurately: from addition to division, skills grow with daily practice.
- Grow focus and number sense: solving problems one by one builds concentration, a feel for numbers, and perseverance.
- Keep going at home with class-quality lessons supervised by a real dojo — even beginners can keep learning as if in class.

■ Who it's for
- Beginners who want to start the abacus, or are considering it as a lesson
- Anyone who wants faster, more accurate mental math and flash anzan
- Parents using the abacus for a child's education and home learning
- Learners who preview/review a soroban class, or can't easily attend one
- Anyone aiming to pass mental-math / abacus exams
- Adults who want brain training and stronger calculation skills
