School AI, a generative AI for education used in 1,600 schools, to be fully introduced in all classrooms of 'Individual Tutoring Academy Success' operated by Success

Minngaku Co., Ltd. (Headquarters: Chuo-ku, Tokyo; Representative Director: Yuta Sato; hereinafter 'Minngaku'), which develops and operates the educational platform 'School AI' centered on education × generative AI, announces that from June 2026, 'School AI' will be fully introduced in all classrooms of the individual tutoring school 'Individual Tutoring Academy Success' operated by Success Co., Ltd. (TSE Growth; hereinafter 'Success'), a group company handling education and welfare human resources infrastructure.

■ Background of Introduction: Toward Balancing 'Work Style Reform' and 'Individualized Optimal Learning' in the Cram School Industry

Currently, the cram school industry faces serious issues such as a shortage of instructors and poor working conditions due to excessive tasks like preparing teaching materials and creating reports. Additionally, with the diversification of entrance exam systems, there is a need to shift from traditional 'teaching' to 'coaching' that supports students' self-study.

'School AI' provided by Minngaku is a safe and secure platform that fully complies with the Ministry of Education guidelines and has already been introduced in over 1,600 schools and local governments nationwide. It received the 'Minister of Internal Affairs and Communications Award' at the 22nd Japan e-Learning Awards.

Based on this track record and safety cultivated in school settings, it will be simultaneously introduced in all classrooms of Individual Tutoring Academy Success. It will establish a new cram school model that achieves work style reform through dramatic efficiency improvements (reduction of man-hours) for instructors and highly accurate individualized instruction for students.

■ What General AI Cannot Imitate: Unique Tuning and Educational Philosophy Realized by 'School AI'

Many general-purpose generative AIs on the market are limited to one-off question-and-answer interactions and cannot capture the learning process during 'time not at the cram school.'

In contrast, 'School AI' has a unique educational philosophy and system design that connects the cram school and home, enabling thorough management of students' 'self-study.'

AI analyzes and provides feedback on 'self-study logs' during time not at the cram school

The AI analyzes the processes and reflection data of self-study conducted by students at home or outside the cram school, and directly feeds them back to the teachers at the classroom. This allows the cram school to accurately grasp learning logs during 'time not at the cram school,' which was often a black box.

'Individualized optimal tuning' according to learning speed and understanding

Based on visualized learning logs, it enables fully personalized responses (perfect hints and encouragement) according to each student's learning speed, tendency to stumble, and current comprehension level. Rather than simply providing answers, the AI accompanies self-study at home, and instructors use that data for face-to-face coaching, realizing true 'individualized optimal instruction' in all Success classrooms.

■ Parents and Classrooms Can Rest Assured! 'Three Safety Nets' Recognized by Schools

To ensure children can use generative AI safely and securely, it is equipped with robust security and management functions not found in general AI tools.

'Complete non-use' of input data for AI retraining

Chat content and personal information entered into 'School AI' are never used for training (retraining) of external AI models.

'Dialogue log confirmation function' by classroom managers and teachers to build a monitoring environment

Classroom managers and instructors can check the logs of interactions between students and AI at any time. Adults can gently watch over whether appropriate learning is taking place, allowing peace of mind when entrusting students to the cram school.

'Content filter' standardly installed to block harmful information

A powerful content filter is implemented to prevent the output of inappropriate expressions or harmful information in educational settings. It thoroughly eliminates the risk of children inadvertently being exposed to dangerous information.

■ Three Value Propositions in All Classrooms of 'Individual Tutoring Academy Success'

[For Instructors] Overwhelming reduction of man-hours through automation of original problem collection and lesson plan creation

Using prompt generation support functions for instructors, it significantly automates and streamlines the creation of original problem sets tailored to individual students, lesson preparation, and drafting of instruction reports. It drastically reduces the 'man-hours for material preparation' that previously relied on instructors' goodwill and private time, promoting work style reform in the cram school industry.

[For Students] 'Learning Supporter' that resolves stumbling on the spot

When students stumble on problem sets or explanations, School AI encourages thinking through dialogue and provides self-study support to deepen understanding. It creates an environment where 'not understanding' is not left unattended, even during after-school home study or study rooms, fostering an independent learning attitude.

[For Students and Instructors] 'Reflection function' that visualizes and links learning trajectories

The AI analyzes and portfolios the interactions and thought processes between students and AI during self-study. Students can visually sense their growth and increase motivation, and instructors can instantly grasp students' 'thinking habits' and 'effort process (learning logs).' This enables more precise and accurate face-to-face instruction within limited class time, allowing hybrid instruction (integration of humans and AI).

■ Future Outlook: Expand to nationwide cram schools and private educational institutions based on the success model at Success

Starting with the full-scale use in all classrooms of 'Individual Tutoring Academy Success' in June 2026, we will first establish a 'new individual instruction model where AI and humans coexist' at that school.

Minngaku will leverage the knowledge and results gained from this practice at Success, and in the future, will not only stay within the group but will also fully promote the introduction and deployment of 'School AI' to nationwide cram schools and private educational institutions. Adding the success model at private cram schools to the track record of over 1,600 school sites, we will strongly promote work style reform and the spread of individualized optimal learning throughout the education industry.

Takeshi Takagi, President and Representative Director of Success Co., Ltd.

The education industry is facing a period of rapid change, including entrance exam reform, work style reform for teachers, and free high school tuition. In addition, local cram schools and individual tutoring schools in urban areas that require many instructors are facing chronic labor shortages. Since its founding, Success has been operating under the motto 'high-quality lessons at low prices.' The full introduction of 'School AI' starting in June will achieve thorough work efficiency and reduction of instructors' man-hours through AI utilization, creating an environment where instructors can focus more on each student. In future education where individualized optimization is increasingly required in terms of learning outcomes and environment, the use of AI is indispensable. Our company will maximize synergy with the group company 'Minngaku' to create a safe and cutting-edge 'future of individual instruction' from here.

Yuta Sato, Representative Director of Minngaku Co., Ltd.

I am delighted that the joint project with Success, which we have nurtured since the capital alliance in 2025, has finally come to fruition in the best form of 'full classroom introduction.' School AI has been refined as a 'learning companion' for children in over 1,500 school sites nationwide. Our strength is not the technology itself, but how we apply it to educational settings.
