About us

Learning is fun!

NINJA STAR was launched in January 2024, with a primary focus on developing children's intelligence and cognition through enjoyable learning experiences in Vancouver, Canada.

Currently, we emphasize the importance of mental arithmetic, and we have introduced a tablet-device-based app called "Sorotouch."

We would be delighted to have you join us on this educational journey!

What is SoroTouch?

Cutting-edge Mental Arithmetic Learning Method

"Sorotouch" is a cutting-edge approach to teaching mental arithmetic, incorporating the principles of the soroban, a Japanese abacus, into a tablet app.


The unique design of the application allows students to enhance their concentration, memorization, and attention skills effectively.


Leveraging our patented technology, students can achieve mastery in mental arithmetic with exceptional efficiency. Notably, within a mere two years, 62% of students reach an advanced level of mental arithmetic.

Study Habits and Success Experiences

Sorotouch is designed for self-learning, and children do not require parental support.


By experiencing growth in ability through daily practice, Sorotouch develops a growth mindset. This mindset not only cultivates a sense of mastery over numbers but also establishes the groundwork for overall learning.


Furthermore, as students incorporate mental arithmetic into their daily lives, they naturally build confidence.

Learn Mental Arithmetic Skills while Having Fun! 

Sorotouch offers 20 exciting and diverse games, over 1000 missions, all featuring adorable characters.


You can enjoy learning by watching instructional videos to grasp game operations and listening to original songs designed for multiplication, and more.


Stay motivated by striving for top rankings through the regularly updated ranking system, and engage in friendly competition with friends worldwide to achieve high scores.

There is no age limit, but an interest in numbers and the ability to understand the explanations in the videos are recommended. The speed of development varies from person to person, so please consult with us if you have any concerns.

On the other hand, research has shown that mental arithmetic is also effective in preventing dementia, and some adults and seniors begin the class for brain training. Parents are also welcome to enroll their children.

For more information, please click here.

Pre-authorized debit (PAD) allows for automatic withdrawals from your account, with the debit date set for the 26th of the preceding month.

You can switch between multiple accounts using a single tablet device. However, individuals enrolled in the same class will require separate devices.

While it is helpful to have parental support during the initial classes, after approximately one month, children will be able to attend classes independently

In online courses, there is generally no waiting time or idle periods, allowing you to focus on your lessons. If you find it challenging to maintain concentration, feel free to inform us so that we can review the lesson content."

We offer classes in the order of the most requested time slots in the survey, without dividing based on age or level.

Questions tailored to each individual's level are presented, ensuring that falling behind compared to other learners is not a concern, even if progress is slower.

Moreover, there are many games and missions that can be played together, even among learners with different levels. Siblings can comfortably attend the same class.

Please choose the course and time that are most convenient for you.

We recommend approximately 2 years. In our previous abacus classes, it took an average of 4.5 years to reach an advanced level, with an overall success rate of around 10%. However, with Sorotouch, more than 60% of students achieve advanced mental arithmetic skills in just two years, with an average duration of 20 months.

The retention rate tends to be lower for students who study alone. By inviting a friend to join the same class and engage in friendly competition, or by enrolling yourself as a parent or guardian and working together with your child, you can expect to maintain a higher level of motivation.

Sorotouch is a learning method that further applies the essence of the classic abacus and specializes in mental arithmetic. Additionally, the program follows a completely original curriculum based on data, ensuring clear and guaranteed results through consistent daily practice, independent of the instructor's proficiency

In July 2023, NINJA STAR signed an agreement with the Flash Anzan Association as Digika Inc. to allow students to take the Flash Anzan Examination sponsored by the Ministry of Education, Culture, Sports, Science and Technology.

NINJA STAR plans to join when students have reached the level of proficiency required to take the certification test.

(Flash Anzan is the process of calculating the numbers that appear randomly and instantaneously on the computer screen.)

There are no specific specifications, so please use the one you already have if available. If you opt to purchase the product, wired has the advantage that there is no risk of forgetting to recharge the battery, no need to check the Bluetooth connection, and it is easier for children to operate.

On the other hand, while wireless is more portable and versatile, there may be a slight delay in audio. Please feel free to choose based on the pros and cons of each option.

You can change the name if it is not already in use. Please contact us using the form.

Kindly bring your tablet and headphones, if you possess them.

You'll have the opportunity to test it on your trial account.

Yes, the fee is $20 per month. A $100 deposit is required, but it will be fully refunded upon return, unless the unit is damaged, submerged, or otherwise unusable.
