Learning e-Portal + AI-powered Textbook "Qubena" Introduced in Tagajo City, Miyagi Prefecture ~All 10 elementary and junior high schools in the city, approximately 5,000 students, to use~

COMPASS Co., Ltd. (Headquarters: Bunkyo-ku, Tokyo; Representative Director: Jun Sato) is pleased to announce that "Qubena," its learning e-portal + AI-powered textbook, has been adopted as part of the instruction in all municipal elementary and junior high schools in Tagajo City, Miyagi Prefecture. Approximately 5,000 elementary and junior high school students across all 10 schools began using the system in March 2026.

Tagajo City has formulated the "Tagajo Smart School ~Education for a New Era Opened by ICT Development and DX~" school ICT concept plan, and is promoting the development of a learning environment to foster students' ability to learn independently and solve problems. This plan prioritizes the advancement and individualization of "individually optimized learning" tailored to each student's learning progress and proficiency, utilizing advanced technologies such as AI. As part of this initiative, to ensure "individually optimized learning" for all students in the city, the learning e-portal + AI-powered textbook "Qubena" has been adopted by all 10 municipal elementary and junior high schools, with approximately 5,000 students from elementary first grade to junior high third grade beginning use in March 2026.

Upon adoption, Qubena's AI, which analyzes students' answer tendencies and proposes effective repetitive learning, was highly evaluated for its potential to simultaneously achieve "improvement of solid academic ability" and "efficiency of learning." Furthermore, Tagajo City aims to use Qubena to streamline the acquisition of basic and fundamental knowledge, thereby freeing up time to dedicate to inquiry-based learning and creative activities (such as PBL).

Comment from Mr. Yoshinori Ichioka, Superintendent of Education, Tagajo City Board of Education

What our city aims for is "guaranteed learning" that leaves no one behind. Qubena's AI instantly analyzes each student's proficiency, making it possible to present optimal assignments. Even if a student encounters difficulties, the AI identifies the cause and enables re-learning, allowing children to progress in their learning proactively while gaining a clear sense of "I understood" and "I could do it."

The time saved through learning efficiency will be dedicated to "inquiry-based learning" and "creative activities" where students discover problems themselves and collaborate with others to solve them. We will support all children in Tagajo City to freely utilize ICT as an everyday partner and design their own learning.

COMPASS will continue to strive to contribute to the further spread of ICT in public education as a leading company that delivers "individually optimized learning" to all children without leaving anyone behind, through the provision of Qubena.
