The organizing committee was formed in Showa 49 (1974), and the first event was held in the following year, Showa 50 (1975). Since then, it has grown to become one of the largest exhibitions in the industry. Reading the themes and directions of each era, we have developed exhibition concepts, bringing together product groups in demand for the times, and have striven for the creation of a rich and comfortable society. This time as well, approximately 200 specialized manufacturers will gather for a comprehensive trade show of electrical materials, housing equipment, information equipment, tools, and industrial machinery, showcasing their integrated capabilities. We will deliver timely and trending new products and the latest information, so please do visit. ■Background of Prodelight's Participation in this Event The "Jumbo Surprise Fair," now in its 52nd year, is one of Japan's largest comprehensive trade shows covering electrical materials, housing equipment, information equipment, tools, and industrial machinery, attracting a wide range of industry professionals. Last year, a total of 481 companies exhibited at both the Tokyo and Osaka venues, with visitor numbers reaching 34,060, demonstrating its high industry attention and drawing power. This exhibition is an important venue for Prodelight to engage in direct dialogue with diverse business professionals and a valuable opportunity to gather candid opinions and on-site challenges from visitors. This real-world feedback is utilized for improving our services and developing new features, leading to the creation of products that are more attuned to the needs of the field.
