10 years as a kindergarten teacher / elementary school teacher / junior and senior high school teacher / childminderkepiko
Graduated from Kunitachi College of Music, Faculty of Music (now: Department of Music Culture and Education, Early Childhood Music Education major). In elementary school, my homeroom teacher was Jun Kusaba, a game researcher. After graduating from university, I worked as a kindergarten teacher for 10 years and as an after-school childcare instructor for 7 years, then took a position as a music teacher at an international school in Singapore. In addition to music education, I engaged in activities that introduced Japanese culture, traditional games, and recreational activities, working with many children. Later, through freelance writing, planning, and editing at Shogakukan, I met many delightful adults and experienced the joy of communicating and sharing. Drawing on the perspective cultivated in the field of education and my experience as an editor, I provide practical information with an emphasis on both input and output, mainly in areas related to music and children. My hobbies include instruments, singing, handicrafts, toys, drawing, traditional games, the outdoors, and books. My special skill is spinning-top tricks.

Magic Circle Magic

[Revealed] Amazing math magic: Instantly make the sum of every column the same number!

Magic Circle Magic

It’s a magic trick where you instantly break down a number suggested by the audience and write it out.

For example, if the number is 35, you split it into four numbers like “7, 2, 17, 9” or “12, 14, 3, 6.” Anyone can do it if they think about it, but producing it in an instant is the impressive part.

What’s more, you write out four such groups of numbers, and no matter how you add them—by rows, columns, diagonals, the four corners, or the center number—they always total 35.

To pull off this trick, you need to memorize a base set of numbers.

Conversely, once you memorize that, you can instantly break down any number they give you!
