COMPASS Inc. (Headquarters: Bunkyo-ku, Tokyo; CEO: Jun Sato) announced that its learning e-portal and AI-based teaching material "Qubena" has been officially adopted as part of the instructional framework in all municipal elementary and junior high schools in Takamatsu City, Kagawa Prefecture, with utilization commencing in April 2026.

Takamatsu City, which has newly adopted Qubena, positions "the enhancement of school education to nurture a zest for life" as one of the fundamental goals of its "3rd Takamatsu City Education Promotion Basic Plan," and is engaged in various measures to "foster solid academic ability" and "promote education utilizing ICT." As part of this initiative, the learning e-portal and AI-based material "Qubena" has been officially adopted and is now being used across all 73 municipal elementary and junior high schools. Approximately 31,000 students from 1st-grade elementary to 3rd-grade junior high school began using the system in April 2026.

In adopting the platform, Qubena was evaluated highly for its AI capabilities, which analyze the "stumbling blocks" of each individual student in real-time, enabling them to pursue personalized learning. Furthermore, expectations have been placed on its ease of use for students, offering operability on one-to-one devices that feels similar to a paper drill.

In addition, future promotion is scheduled for the utilization of educational data through the linkage of Qubena's learning data with Kagawa Prefecture's proprietary educational dashboard.

Comment from Kazuyo Koyanagi, Superintendent of Education, Takamatsu City Board of Education

In this city, based on the fundamental concepts of "education where no one is left behind and each individual shines" and "education that makes people glad they grew up, learned, and lived in Takamatsu," we are advancing education that values collaboration and cooperation between schools, families, and communities, so that diverse individuals can feel happiness and a sense of purpose, while regions and society can feel happiness and abundance.

By introducing Qubena at this time, we will utilize one-to-one devices at home as well, bridging learning between school and home to cultivate the habit of self-directed study and deepen learning. By combining personalized learning according to individual progress through Qubena with collaborative learning such as peer referencing in a cloud environment, and promoting instructional improvements to be student-centered, we enable the integrated enhancement of individually optimized learning and collaborative learning.

Moreover, through its automatic grading and dashboard functions, we expect it to go beyond simply reducing administrative burdens, enabling highly accurate observation based on objective data. At the same time, we hope it will convert the time saved into direct instruction and support facing students, leading to the compatibility of work style reform and qualitative improvement in educational activities.

COMPASS will continue to strive to contribute to the further spread of ICT in public education as a leading company delivering "individually optimized learning" without leaving any child behind, through the continued provision of Qubena.
