About this event
Energy Innovation Exhibition
The Energy Innovation Exhibition is an industry event created to support Japan’s transition toward carbon neutrality by 2050. As part of the ENEX / Renewable Energy World Exhibition / Offshore Tech Japan / InterAqua umbrella, this exhibition focuses on generating business matching opportunities that connect technologies and solutions across energy optimization, decarbonization, renewable energy deployment, water treatment, and marine development.
The exhibition is designed around the themes of GX (Green Transformation) and DX (Digital Transformation), with a clear emphasis on improving the way energy is used, accelerating energy-saving initiatives, expanding renewable energy adoption, and leveraging water processing technologies. In addition, it targets OX (Ocean Transformation), creating a marketplace for business collaboration related to ocean and marine development.
This event is scheduled to be held in December 2026 at Tokyo Big Sight, Tokyo, Japan.
Four participating exhibitions under one platform
The Energy Innovation Exhibition consists of four specialized exhibitions that collectively cover the major priorities of sustainable growth and resource conservation:
- Innovative energy saving / comprehensive exhibition of decarbonization technologies
- Renewable Energy Exhibition (focused on the utilization of renewable energy)
- Offshore Tech Japan / Marine Industry Technology Exhibition (focused on marine resources and related technologies)
- InterAqua / Water Business Exhibition (focused on water solutions and water-related business needs)
What the exhibition aims to achieve
The Energy Innovation Exhibition was created to help organizations find practical collaboration pathways by connecting innovation providers with business stakeholders seeking new solutions. By bringing together multiple solution areas—energy saving, renewable energy, marine development, and water treatment—the event is structured to support sustainable industry activity and long-term transformation.
Business matching focused on GX and DX
A key value of the exhibition is its role as a business-matching platform. It supports engagement between organizations working on energy optimization through GX and DX, companies advancing decarbonization technologies, and stakeholders looking to apply renewable energy, water treatment solutions, and marine development technologies toward OX realization.
Overall, the Energy Innovation Exhibition provides a single venue where innovation and implementation needs can meet—advancing technology adoption for energy conservation, renewables, and sustainable marine and water-related initiatives.
