Hi, I'm Sensei Miwako

I'm here to share a simple and fun way that Japanese use to take care of their brains. You deserve to know that, too. For years I asked myself these questions: Why do children in America struggle so much with math? How come adults don’t practice Abacus or Sudoku to boost brain health? I’ve been a pioneer in bringing Abacus into the lives of thousands of people here in the U.S. For the last 25 years, I've helped Americans move beyond their fear of cognitive decline and take back control of their lives. Now it's your turn. Join me on this Abacus journey and learn the ancient Japanese secret.
And get ready to tap into your brain’s full potential!

Three simple steps and you are there!

"Alzheimer's runs in my family. I gifted this course to my mother and now she brags about her math skills. It's improved her life immensely, and she loves it."
