14th Undergrounding Promotion Exhibition 2026 at Tokyo Big Sight

The 14th Undergrounding Promotion Exhibition will be held at Tokyo Big Sight in Ariake, Koto-ku, Tokyo, from July 15 (Wed) to July 17 (Fri), 2026. This exhibition is a specialized B2B trade show focusing on technologies and services that promote the creation of safe and comfortable towns without utility poles.

Exhibition Overview and Objectives

In recent years, the necessity of undergrounding utility poles has been increasing due to the intensification of disasters and the aging of society. In particular, prolonged power outages and communication disruptions caused by typhoons and heavy rains highlight the importance of strengthening the resilience of power and communication infrastructure. Against this backdrop, the exhibition aims to bring together the latest technologies and related materials for achieving undergrounding. It offers an excellent opportunity to explore new urban development solutions that can be implemented at low cost.

Exhibitor and Visitor Target Audience

The exhibition will feature a wide range of products and technologies related to undergrounding, including electrical equipment (wires, sewage and water pipes, utility tunnels, lighting, various sensors, etc.), waste treatment equipment and technologies, buried object management systems, and excavation machinery. The target visitors include general contractors, construction consultants, engineering companies, building material manufacturers, electrical equipment manufacturers, road-related organizations, power and gas companies, research institutions, developers, local government officials, chambers of commerce, and trading companies. It will serve as a platform for industry professionals to grasp the latest technological trends and discover new business opportunities.

Notable Seminars and Lectures

During the exhibition, several seminars and lectures related to the promotion of undergrounding will be held. On July 15, there will be sessions on Tokyo's undergrounding initiatives, the utilization of new technologies in public works, and the promotion of national resilience. Lectures by the Tokyo Metro Group on their DX challenges and keynote speeches on building a resilient society are also planned, offering insights into the latest policy trends and best practices.
