Japan IT Week Spring is the country’s largest trade show for enterprise IT, running from April 24–26, 2024, at Tokyo Big Sight. The event is strictly in-person and expects roughly 70,000 executives, systems planners, developers, purchasing managers and public-sector CIOOs. Twelve specialised shows run in parallel: AI & Business Automation, Cloud & BPR, Data Centre, Information Security, Big Data, IoT, Embedded Systems, Software & App Development, Marketing, e-Commerce, Retail Tech and Fintech. Each zone is curated so that every visitor can benchmark the full stack of current and emerging technologies in a single venue. The 2024 edition is anchored by a keynote from Digital Minister Taro Kono on “Digital Garden City 2.0”, followed by case-study tracks led by Toyota, Mizuho Bank, Fast Retailing, NEC, Fujitsu and SoftBank. Sessions dissect live deployments of generative AI in manufacturing, zero-trust security in hybrid work, and green data-centre design that meets Japan’s 2025 energy-efficiency mandates. A parallel conference for start-ups hosts 120 seed-stage companies pitching to corporate venture arms. The show floor is arranged into demonstration districts: an AI Robot Lab where visitors can programme collaborative arms, a Cyber Range that simulates ransomware attacks on OT networks, and a Sustainability Pavilion comparing liquid-cooling racks. Government pavilions from Estonia, Israel, Canada and Thailand promote cross-border R&D partnerships. Attendance is free after online registration; conference passes grant access to 180 lectures and half-day tutorials. The organiser, RX Japan, positions the event as the first stop in the domestic buying cycle: 72 % of 2023 visitors held budget authority exceeding 50 million yen and 63 % planned to place orders within six months. Post-show reports indicate that exhibitors booked 5.4 billion yen of provisional contracts last spring. Concurrent fringe events include job-match corners for IT engineers, export-compliance clinics and closed-door procurement meetings between systems integrators and ministries handling the My Number digital-ID overhaul.
