Qubena

What Qubena does

COMPASS Inc. operates Qubena (キュビナ), an AI-powered adaptive learning platform deployed across Japanese K-12 public education. The platform uses machine learning to analyze each student's error patterns and mastery level, automatically selecting and sequencing optimal practice problems across 9 subjects — mathematics, Japanese language, science, social studies, English, music, art, physical education, and technology/home economics. The core technology includes a proprietary adaptive recommendation engine, a patent-pending Smart Workbook retention-based review sequencing system, and proprietary handwritten character recognition for automated grading across multiple response formats. The Learning e-Portal architecture integrates via LTI with Japan's national digital textbook distribution systems (Mirai School Platform, L-Gate) and with the MEXT-operated MEXCBT computer-based testing platform.

The company sells exclusively to municipal and ward-level education boards (教育委員会/教育局) and public schools in Japan via direct enterprise field sales and formal government procurement processes. The revenue model is B2B annual subscription pricing per student, with two tiers: a Starter Edition at ¥1,320/student/year for new municipal adoptions and a quote-based Standard Edition for established deployments. Larger municipal contracts (e.g., Fukuoka City, Nagoya) bundle professional services including dispatched ICT support staff. The company is the dominant adaptive learning vendor in Japan's public education sector, deployed across 170+ municipalities, approximately 2,300 schools, and 1M+ students as of 2025-2026, with cumulative answer count exceeding 3 billion. The product portfolio has expanded beyond adaptive drill to include Qubena Test (digital assessment), SPARKE (inquiry-based learning library co-developed with ShoPro and corporate partners including the Pokémon Company), and integrations with MEXT's national education data standards. Government endorsements include three consecutive years (2018-2020) in METI's Future Classroom demonstration project, EdTech Subsidy selection (2021, 2022), and JIS Q 27001:2025 information security certification.

Revenue model

1. School/District Subscription (B2B SaaS): COMPASS sells subscription licenses to municipal education boards and individual public schools. Pricing is based on the number of schools and enrolled students within a municipality. Annual subscription model. Large municipalities (e.g., Nagoya, Fukuoka City, Fukuoka Prefecture) are served with dedicated account management and ICT support staff alongside the software subscription. The キュビナ スターター版 (Starter Edition) targets new municipalities at a lower price point (annual fee per student) to facilitate initial adoption.
2. ICT Support Services (ICT支援員派遣): In some municipal contracts (e.g., Fukuoka City), COMPASS provides ICT support staff (ICT支援員) dispatched to schools alongside the software license, supporting implementation and ongoing utilization. This adds a professional services component to the revenue stream.

Core offering

Qubena is an AI-powered adaptive e-learning platform sold to Japanese public elementary and junior high schools (K-12). The platform uses machine learning to diagnose each student's individual knowledge gaps and automatically sequences personalized practice problems across 9 subjects, with textbook-aligned content, teacher dashboards, and LTI integration with national digital textbook ecosystems. Sold as annual subscriptions to municipal education boards and ward-level education offices, with over 1 million students across 2,300+ schools and 170+ municipalities as of 2025-2026.

Product overview

Qubena is an AI-powered adaptive e-learning platform for K-12 (elementary and middle school) students operated by COMPASS Inc. The core product combines an AI diagnostic engine that automatically identifies individual student knowledge gaps with an adaptive recommendation engine that personalizes problem selection and sequencing. The platform has expanded from an initial 2-subject offering (mathematics and English) to a 9-subject platform covering core academic subjects plus music, art, physical education, and technology/home economics. The product portfolio consists of the core Qubena adaptive e-portal complemented by several modules: Qubena Manager (teacher administration dashboard with parent reporting via LINE), Qubena Test (digital assessment delivery integrated with MEXCBT), Qubena Smart Workbooks (supplementary drill practice), Qubena Lite (lower-cost starter version for new municipalities), Cubina (AI-based teaching materials with LTI digital textbook integration), and SPARKE (an inquiry-based learning library available alongside the adaptive learning platform). Qubena integrates with multiple Japanese digital textbook publishers via LTI through the みらいスクールプラットフォーム, and connects with MEXCBT for national standardized testing correlation analysis, enabling interoperability with Japan's national education technology ecosystem.
