Sustainable Mobility Technology Expo SuM-TECH Tokyo

The Sustainable Mobility Technology Expo (SuM-TECH) is a specialized trade fair with a clear focus on sustainable mobility. Held annually as part of the renowned AUTOMOTIVE WORLD, the event takes place at Tokyo Big Sight – in the heart of Japan’s capital, Tokyo, a global hub for innovation, technology, and business. Organized by RX Japan Ltd., one of Asia’s leading exhibition companies, SuM-TECH brings together key players in future-oriented automotive technologies at a strategically significant location.

At its core, the expo showcases technological solutions for climate-neutral and resource-efficient mobility. The focus is not only on pioneering products, but also on their practical integration into industrial processes. SuM-TECH positions itself as a highly specialized forum for application-driven innovation and active exchange between industry and research.

Key topics include eco-friendly materials, advanced recycling technologies for batteries and vehicle components, and low-emission manufacturing processes. Developments in synthetic fuels, hydrogen technology, and energy or CO₂ monitoring are also featured prominently. Lightweight construction using high-strength materials, along with contributions from startups and research institutions, broaden the spectrum with visionary perspectives.

The event targets companies and institutions dedicated to sustainable technologies aimed at reducing CO₂ emissions and increasing efficiency across the automotive value chain. Trade visitors from the fields of automotive manufacturing, mechanical engineering, chemistry, materials development, environmental and energy technologies will find opportunities to connect with decision-makers and innovation leaders from Japan, across Asia, and around the globe.

As an integral part of AUTOMOTIVE WORLD, SuM-TECH is embedded in a comprehensive exhibition format with locations in both Tokyo and Nagoya. This structure offers international companies an ideal platform to enter the Japanese market or expand existing business relationships.
