Learning e-Portal + AI-Powered Teaching Material 'Qubena' Adopted in Tagajo City, Miyagi Prefecture: Used by Approximately 5,000 Students Across All 10 Municipal Elementary and Junior High Schools

COMPASS Co., Ltd. (Headquarters: Bunkyo-ku, Tokyo; Representative Director: Jun Sato) is pleased to announce that its learning e-portal and AI-powered teaching material, 'Qubena,' has been adopted as part of the curriculum for all municipal elementary and junior high schools in Tagajo City, Miyagi Prefecture. As of March 2026, approximately 5,000 students across all 10 schools have begun using the platform.

Tagajo City has formulated a school ICT initiative plan titled 'Tagajo City Smart School: Education for a New Era Opened by ICT Infrastructure and DX,' and is advancing the development of a learning environment designed to foster students' ability to learn independently and solve problems. A key policy of this plan is to utilize cutting-edge technologies, such as AI, to enhance and individualize 'individually optimized learning' based on each student's learning progress and proficiency. As part of this effort, and to ensure 'individually optimized learning' for all students in the city, the learning e-portal and AI-powered teaching material 'Qubena' was adopted by all 10 municipal elementary and junior high schools, with approximately 5,000 students from first grade of elementary school to third grade of junior high school beginning use in March 2026.

During the selection process, Qubena was highly evaluated for its AI-driven ability to analyze student response patterns and suggest effective repetitive learning, which is seen as a way to simultaneously achieve 'solid academic improvement' and 'learning efficiency.' Furthermore, the city aims to use the time saved through the efficiency gains provided by Qubena to focus on inquiry-based learning and creative activities (such as PBL).

Comment from Yoshinori Ichioka, Superintendent of the Tagajo City Board of Education: 'What our city aims for is the "guarantee of learning" that leaves no one behind. By having Qubena’s AI instantly analyze the proficiency of each individual student, it has become possible to present the most optimal assignments. Even if a student encounters a stumbling block, the AI can identify the cause and allow them to relearn the material, enabling children to proactively advance their studies while gaining a solid sense of accomplishment—the feeling of "I understand" and "I can do it."

The time created through the efficiency of learning will be channeled into "inquiry-based learning" and "creative activities" where students discover problems themselves and collaborate with others to tackle solutions. We will support all children in Tagajo City so that they can freely master ICT as a daily partner and design their own learning.'

COMPASS remains committed to being a leading company that delivers 'individually optimized learning' without leaving any child behind, and we will continue to strive to contribute to the further spread of ICT in public education through the provision of Qubena.
