Japan IT Week Spring is the country’s largest trade gathering for enterprise IT professionals, held annually at Tokyo Big Sight. The 2024 edition ran 24-26 April and comprised eight co-located shows: AI & Business Automation, Cloud & BPR, Information Security, Data Center & Storage, Web & Digital Marketing, Embedded Systems, Software & App Development, and the newly added DX Human Resource Development Expo. Together they filled four halls with 1,700 exhibitors occupying 3,900 booths and drew 76,000 visitors over three days, making it the most attended spring technology marketplace in Japan. The audience is dominated by corporate IT managers, systems integrators, software vendors, government agencies and manufacturers seeking ready-to-deploy solutions rather than theoretical concepts. The format is strictly in-person; no hybrid streaming is offered so that buyers can benchmark hardware, test software live and negotiate contracts on the spot. Conference chairs stressed three urgent themes: generative-AI integration, zero-trust security for remote work, and carbon-efficient data centres. Keynote speakers included Digital Agency CIO Tetsushi Sakamoto on “Digital Garden City Nation 2.0”, Microsoft Japan CTO Yuzo Koga demonstrating Azure OpenAI deployments, and NTT Data EVP Yuko Harada outlining post-5G network automation. More than 300 parallel seminars and sponsored workshops ran concurrently with the exhibition, covering practical topics such as prompt-engineering for legacy code, compliance with Japan’s new ISMS 2023 standard, and cost optimisation when migrating mainframes to containerised cloud. A dedicated “Start-up & Investor Zone” hosted 120 young companies pitching edge-AI chips, quantum-safe cryptography and low-code platforms to venture funds, while the “DX Manager Lounge” provided closed-door roundtables for chief digital officers exchanging KPI playbooks. Visitor badges were encoded with NFC so exhibitors could scan leads instantly; post-show analytics showed the average attendee held 18 solution meetings and requested follow-up demos within two weeks. Organiser RX Japan stated that 92 % of exhibitors secured qualified sales pipelines on site, and 85 % of visitors found products they intended to budget for in the next fiscal year.
