Sustainable Mobility Technology Expo SuM-TECH Chiba

The Sustainable Mobility Technology Expo (SuM-TECH) is a trade fair with a clear focus on sustainable mobility. As part of the renowned AUTOMOTIVE WORLD, it is held annually at Makuhari Messe in Chiba – just outside Tokyo, in one of Japan’s most vibrant economic regions. The event is organized by RX Japan Ltd., one of Asia’s leading trade show organizers. SuM-TECH brings together key players in forward-looking automotive technologies.

At its core, the expo highlights technological solutions for climate-neutral and resource-efficient mobility. The focus extends beyond innovative products to include their practical implementation in industrial processes. The event serves as a highly specialized platform for hands-on solutions and interdisciplinary dialogue between industry and research.

Topics covered include new environmentally friendly materials, advanced recycling methods for batteries and vehicle components, and climate-conscious production processes. Breakthroughs in synthetic fuels, hydrogen technology, and energy and CO₂ monitoring are also showcased. Lightweight construction using high-strength materials, as well as contributions from start-ups and research institutions, add visionary perspectives to the lineup.

The expo is aimed at companies and institutions interested in sustainable technologies for reducing CO₂ emissions and increasing efficiency along the automotive value chain. Trade visitors from sectors such as automotive manufacturing, mechanical engineering, chemical processing, materials development, and environmental and energy technologies come together with decision-makers and innovation leaders from Japan, across Asia, and around the globe.

As a key part of AUTOMOTIVE WORLD, SuM-TECH is integrated into a comprehensive trade fair concept, with additional venues in Tokyo and Nagoya. This structure offers international companies a targeted opportunity to enter the Japanese market or expand existing business relationships.

Makuhari Messe stands out with its modern infrastructure and excellent transport links – located just 30 minutes from central Tokyo and easily accessible from Narita and Haneda airports. These advantages make it an ideal venue for a successful trade show presence in one of East Asia’s most innovative economic hubs.

The Sustainable Mobility Technology Expo SuM-TECH will take place on 3 days from Wednesday, 09. September to Friday, 11. September 2026 in Chiba.
