Manten Kids (まんてんキッズ)

Nurture "the ability to think logically" through two approaches: Pygmalion (math) and Ronri Engine (Japanese).

The ability to think is essential to a fulfilling life. The ability to think is also the basis of all subjects.

Have you ever had this problem? You can't wait for your children to think for themselves and end up teaching them instead. You try to make your child memorize things. It's frustrating, isn't it? Your children will not develop the ability to think for themselves just by being taught. They grow when they are thinking hard. At Manten Kids, we support children's education by providing original teaching tools that excite them just by looking at them, and a variety of printouts that make them want to try things out for themselves.

Have you ever had a situation like this? You are forcing your child to practice only reading, writing, and calculating. It is not fun, is it?

Especially with numbers, if children are taught only by counting and repetitive calculation, they may be able to calculate small numbers, but when it comes to large numbers and sentences, they quickly lose the ability to do so.

Please contact Manten Kids (まんてんキッズ) in Japanese directly for details including enrollment.

Pygmalion (in Japanese) - Age 2 to Elementary Students

At Pygmalion, children learn number concepts through a variety of teaching materials, teaching tools, and fun games that give them a sense of quantity.

And, five learning points are stimulated in a well-balanced manner each time.

  1. (1)Finger Dexterity: A vital skill that influences all abilities. It fosters the development of independence.
  2. (2)Spatial Ability: Cultivates an understanding of space, position, structure, and develops a broadened perspective and decision-making skills.
  3. (3)Shape Ability: The secrets to nurturing thinking and creativity lie within the rich world of shape play.
  4. (4)Numerical-Logical Ability: It's not just about counting numbers, but also about fostering creativity, feeling quantities visually, and grasping the concept of numbers. Problem-solving abilities are nurtured.
  5. (5)Language Ability: Develops a living language skill not just as mere characters but for thought and communication.

Actively thinking, solving, and creating on one's own leads to the ability to tackle subsequent challenges. Indeed, cultivating this sought-after strength is the education that Pygmalion aims to provide.

There are two courses available at Pygmalion:

(1) Super Pygmalion (Age 2 to Grade 3)

  • One-on-one personalized instruction
  • Custom-made curriculum tailored to the child's characteristics
  • Parents can attend to learn teaching methods for use at home
  • Aims to master four-digit addition and subtraction before starting school, making it the most accelerated course
  • Uses all of Pygmalion's teaching materials (about 40 sheets per hour)

(2) Pygmalion Petit α (Age 3 to Grade 4)

  • Group lessons with up to 3 students per class (no parents attend)
  • Adapted Super Pygmalion content for group sessions (about 10 printouts per hour)
  • A comprehensive curriculum that can be reliably covered in a group
  • Offered at an affordable price

Ronri Engine (in Japanese) - Elementary Students

The Ronri Engine (論理エンジン) nurtures logical thinking through an approach based on the Japanese language. Reading comprehension is necessary for any subject, in any era, and in any profession.


  • The Japanese language is just about having a feel for it, so studying or not studying makes no difference.
  • Even without studying, one can score decently in Japanese.
  • Japanese language studies are merely about learning kanji and reading aloud.
  • The only way I can think of studying Japanese is through reading.
  • After all, it's just Japanese, so there's no need to study.

Current State:

  • Lack of logical and thinking skills.
  • Lack of reading comprehension.
  • Lack of vocabulary.
  • Lack of expression.
  • Lack of awareness of others.
  • Unfamiliar with correct grammar.

Can these be ignored?

In the Ronri Engine Japanese course, we ensure mastery by balancing language, logic, thinking, expression, and grammar, adopting a small-step, spiral approach.

With logical reading comprehension, you can objectively interpret word problems.
With logical thinking skills, you can write accurate sentences in descriptive problems and compositions.
With logical expression skills, you can convey your points clearly to others.

There are four pillars to enhance logical reading comprehension and descriptive abilities:

  1. (1)Equivalence Relationship: A creative combination enhances the persuasiveness of an argument.
  2. (2)Contrasting Relationship: A stark contrast enhances the impact of an assertion.
  3. (3)Cause-and-Effect Relationship: The core logic of a new era (showing the relation between cause and result).
  4. (4)Relationship of Subject, Predicate, and Object: Captures the essence of a sentence.
