POWER SUPPLY JAPAN Tokyo

POWER SUPPLY JAPAN is Japan’s leading trade fair for power supply technologies and the country’s only dedicated event focused exclusively on power supply systems, power conversion technologies and electronic components. The exhibition’s name incorporates the English term “Power Supply”, which refers to the provision and management of electrical power.

Each summer, professionals from across Asia and the global energy and electronics industries gather at Tokyo Big Sight in Tokyo. The event is organised by the Japan Management Association (JMA), one of Japan’s most respected business and management organisations, which has been promoting technological innovation and industrial development through trade fairs and industry platforms for decades. POWER SUPPLY JAPAN is also part of TECHNO-FRONTIER, a major exhibition for electronics, mechatronics and drive technologies, enabling visitors to benefit from valuable synergies with related technology sectors.

The exhibition focuses on advanced solutions for reliable, efficient and sustainable power supply. It showcases the latest developments in power supply engineering, electronic components, battery technologies, power conversion, energy management and next-generation power supply systems. Exhibitors also present innovative adapters and chargers, uninterruptible power supplies (UPS), inverters and power conditioners, switched-mode power supplies, capacitors, semiconductor components, testing and measurement equipment, and technologies designed to reduce harmonic distortion. The products and services on display play an important role in improving energy efficiency, enhancing operational reliability and meeting the demands of modern industrial applications.

Exhibitors primarily represent the electronics, semiconductor, power supply, battery technology, power generation, automotive and industrial infrastructure sectors. Key visitor groups include development engineers, design engineers, research and development managers, and technical decision-makers from industries such as mechanical engineering, automotive engineering, electrical engineering, precision engineering, industrial automation and energy technology. The exhibition serves as a key platform for exchange and collaboration between manufacturers, suppliers and users of advanced power supply solutions.

One of the defining features of POWER SUPPLY JAPAN is its dedicated focus on power conversion and secure energy supply technologies. Within Japan, it occupies a unique position as a highly specialised event in this field. The exhibition is complemented by a comprehensive conference programme featuring expert presentations, technical seminars and industry forums where current market trends, emerging technologies and future industry requirements are explored and discussed. Knowledge sharing, professional networking and business development are at the heart of the event.

The exhibition highlights Japan’s position as one of the world’s leading centres for electronics, energy efficiency and industrial innovation. In particular, the Tokyo metropolitan area, with its high concentration of technology companies, research institutions and major industrial corporations, provides an ideal setting for an international trade event of this calibre.

The venue is Tokyo Big Sight, Japan’s largest exhibition and convention centre. Located on the man-made island of Odaiba in Tokyo Bay, its distinctive architecture has become one of the most recognisable landmarks in Japan’s exhibition industry. Thanks to excellent transport links, the venue is easily accessible via Tokyo’s extensive rail and public transport network. At the same time, it offers visitors the opportunity to experience one of the world’s most innovative and economically significant metropolitan centres.

The POWER SUPPLY JAPAN will take place on 3 days from Wednesday, 15. July to Friday, 17. July 2026 in Tokyo.
