UL Solutions Inc. announced the opening of a new automotive electromagnetic compatibility (EMC) laboratory in Toyota City, Japan, expanding its testing capabilities to support increasingly complex vehicle technologies in one of the world's largest automotive markets.

The new Automotive Technology and Innovation Center will begin operations on July 1. The facility provides automotive electromagnetic compatibility (EMC) testing designed to help manufacturers protect vehicles from interference that can disrupt systems such as braking, steering, and engine control. As vehicles incorporate more electronics, faster processing speeds, and higher-voltage systems, the need for EMC testing continues to grow.

“Automakers are moving faster, integrating more electronics and facing increasing regulatory and market demands,” said Alex Dadakis, executive vice president and president, Testing, Inspection and Certification, UL Solutions. “This new laboratory strengthens our ability to support customers in Japan and around the world with independent, science-based EMC testing that reflects real-world vehicle conditions.”

The facility is designed to support autonomous and software-defined vehicles and compressed development cycles by providing automakers and suppliers with access to advanced EMC testing. Located in Japan's Tokai region, the center of the country's automotive industry, the 2,322.58-square-meter (25,000-square-foot) facility is among the EMC laboratories in Japan equipped for high-voltage, high-current, high-torque, and high-speed rotational testing.

Automotive EMC testing helps manufacturers demonstrate compliance with global standards, support market entry, and reduce the risk of malfunctions caused by electromagnetic interference. Japan, the world's third-largest vehicle producer, manufactured more than 8 million vehicles in 2025, according to Statbase.

“Japan is a cornerstone of the global automotive industry and a vital market for our customers,” said Hidehiko Yamajo, regional vice president, Japan, UL Solutions. “This new facility enhances our world-class EMC capabilities and deepens our support for automakers and suppliers as they bring increasingly sophisticated vehicles to market.”

The Toyota City laboratory expands UL Solutions' automotive EMC testing operations in Japan, complementing the Automotive Technology Center in Miyoshi City and adding to the company's testing network across Asia, Europe, and North America.

The laboratory includes chambers capable of handling up to 25,000 RPM, more than 3,500 Nm torque, and power supplies delivering up to 1,500 volts and 1,000 amps. These capabilities support testing for passenger vehicles and high-voltage, high-current, and high-power automotive electrical systems under demanding operating conditions.
