01
Start from the problem
We ask 'What needs to be solved?' before 'What can AI do?' We aim for production systems from day one, not proof-of-concepts that stop there.
Software development, reimagined with AI.
Production AI systems
and cross-border software.
GENGAKUTAKU INC. helps Japanese companies design, build, and operate the next generation of AI applications, global products, and practical digital workflows.

2025Finance
Internal document RAG system — design and build
Designed and built a RAG system over tens of thousands of internal policies, manuals, and inquiry records, enabling natural-language search and answer generation. Deployed on-premise to meet strict data residency requirements with zero external data transmission.
Outcome: Reduced average inquiry response time by 40%. Also shortened new-hire onboarding period.
2025SaaS
Japan-origin SaaS — Greater China localization
Supported the Greater China expansion of a growing Japanese B2B SaaS product. Redesigned the i18n architecture, implemented Simplified and Traditional Chinese support, optimized CDN delivery for mainland China, and ensured PIPL compliance — all in one engagement.
Outcome: Improved page load time in Greater China to under 3 seconds. Local user count reached target within 3 months post-launch.
2026SMB (Services)
Excel-to-SaaS migration and process redesign
Migrated a 20-person service company from Excel-and-paper operations (accounting, attendance, contracts) to cloud SaaS. Completed the full cycle from As-Is process mapping through To-Be redesign, tool setup, staff training, and adoption support in 3 months.
Outcome: Shortened monthly closing from 5 business days to 2. Fully digitized paper-based contract management.
Operating Method
We do not stop at PoC. We design for operation.
Discovery, architecture, implementation, evaluation, and operations are treated as one continuous system. AI adoption and product development move forward with clear decision points.
02
Start small, move fast
PoC in 2 weeks, MVP in 4 to 8. We stack visible results instead of making grand plans.
03
Own the outcome
Delivery is not the finish line. We take responsibility through operations, maintenance, and improvement. We walk the full lifecycle with our clients.
Global
Japan and China, one team.
Chinese AI implementation velocity and Japanese quality standards — woven into a single engineering organization that supports overseas expansion and new product development.

Google Cloud adds new data agents across the Agentic Data Cloud
Google expanded conversational analytics and Data Agent Kit across BigQuery, Lakehouse, Looker, and databases. The update pushes agents closer to governed enterprise data instead of leaving them as generic chat layers.
OpenAI introduces Partner Network for enterprise AI transformation
OpenAI announced a global partner program focused on turning enterprise AI ambition into measurable outcomes. The emphasis is shifting from model access to use-case discovery, workflow redesign, integration, and change management.
Anthropic and TCS partner to bring Claude to regulated industries
TCS will provide Claude to 50,000 employees across 56 countries and build industry offerings for finance, healthcare, public sector, and other regulated fields. The center of gravity is auditable, compliant AI in production.
OpenAI named a Leader in enterprise AI coding agents by Gartner
OpenAI says Codex is used by more than 4 million people weekly and is expanding from code generation into review, testing, incident response, and large-repository reasoning. Enterprise adoption is being judged on controls, sandboxing, RBAC, and auditability.
OpenAI and Dell partner to bring Codex to hybrid and on-premises environments
OpenAI and Dell plan to bring Codex closer to governed enterprise data through Dell AI Data Platform and AI Factory environments. The signal is clear: agent value rises when execution sits near internal context and controls.
