NTQ Japan’s AI Modernization Shines At Japan IT Week 2026

Japan IT Week 2026 – One of Japan’s largest annual technology exhibitions & showcases took place in Tokyo Big Sight, attracting more than 100,000 visitors and 1800+ exhibitors showcasing top-notch digital innovations in multiple sectors, including AI, IoT, Security & Cloud… NTQ Japan was one of the companies taking part in the exhibition sections, impressing global audiences with its’ key competencies in AI Modernization. 

Key Exhibition Highlights – AI Testing, Modernization, and In-depth Speech

Coming into this year’s exhibition, NTQ Japan highlighted its’ key capabilities in researching & developing AI-powered solutions that leverage effectiveness in delivering projects, contributing to add significant impacts that harness enterprises’ digital transformation journey. One of the most significant features includes: 

• NxTest: An AI-powered automated testing solution designed to significantly improve accuracy while accelerating execution speed compared to traditional manual testing methods. By leveraging AI, NxTest enables enterprises to optimize quality assurance processes, reduce human effort, and shorten time-to-market – A critical factors in today’s fast-moving digital landscape.
• AI Modernization: NTQ Japan’s approach addresses one of the most pressing challenges faced by enterprises: transforming legacy systems into scalable, future-ready platforms. These solutions attracted strong interest from Japanese enterprises, particularly as many organizations continue to struggle with outdated systems that are difficult to maintain, costly to upgrade, and increasingly incompatible with modern business requirements.

Along with introducing key solutions, NTQ Consulting Japan’s CEO – Mr. Ishikawa Akira, delivered a featured presentation, offering a grounded and practical perspective on how AI can be effectively applied in system modernization. 

According to Ishikawa Akira, many enterprises are approaching a critical transition point, driven by aging legacy systems, workforce shortages, and the gradual loss of system documentation that leaves only source code behind. This creates significant risks in maintaining and upgrading existing systems.

AI has emerged as a promising solution, with the potential to shorten system migration timelines from 1.5–3 years to just 6–12 months. However, conventional AI approaches, especially those relying heavily on large language models (LLMs), still face key limitations. These include context loss when handling large codebases, inconsistent outputs over time, and the risk of “hallucinations,” where generated results appear correct but fail in business logic or introduce hidden errors. As a result, relying solely on AI without proper control mechanisms can lead to unpredictable outcomes.

To address these challenges, NTQ Japan’s representatives proposed a structured approach to AI Modernization through its Smart Rewrite methodology that balances between quality control & delivered outcomes, which is centric around key components including: 

• Understand the system before transforming it: Instead of feeding legacy code directly into AI, Smart Rewrite first breaks it down into structured components (using AST) to fully understand the underlying logic. This allows AI to work with well-organized data rather than “guessing,” reducing errors from the very beginning.
• Controlled transformation, not fully dependent on AI: The transformation process is carried out step by step, combining rule-based methods with AI. Each stage is monitored through a Quality Gate, ensuring that outputs are accurate, consistent, and verifiable – Rather than relying entirely on AI-generated results.
• Build modern systems, not just translate old ones: Rather than simply rewriting legacy code into a new language, Smart Rewrite focuses on restructuring systems based on modern architectural principles (such as Clean Architecture). This ensures that the new system is scalable, maintainable, and ready for future growth.
• Effort Inversion: Thanks to a manageable AI integration, humans’ efforts in modernization will be shifted to strategic design & quality control, significantly reducing the time to analyze & understand the legacy code. 

Strengthening Presence Through Leading Tech Exhibitions

NTQ Japan’s solutions received highly positive feedback from visitors and industry professionals at the exhibition. Many enterprises, particularly large organizations undergoing digital transformation, showed strong interest in the company’s AI-driven offerings, recognizing their practicality and immediate applicability. Notably, a number of potential partners expressed their willingness to explore collaboration opportunities, aiming to leverage NTQ Japan’s solutions to enhance operational efficiency and accelerate system modernization initiatives.

NTQ Japan’s participation in Japan IT Week 2026 reflects its ongoing commitment to engaging with leading technology platforms in Japan. These exhibitions serve not only as opportunities to showcase capabilities, but also as important touchpoints for connecting with enterprises, exchanging insights, and understanding evolving market demands.

Over the years, NTQ Japan has consistently made strong impressions through its technological expertise and practical solutions. More importantly, its presence at major industry events has contributed to elevating the visibility of Vietnamese technology on the global stage: Demonstrating a clear, confident, and increasingly impactful role in one of the world’s most advanced technology markets.
