Exhibiting a Concept of Integrating ReFa HYDRAID into LEXUS Vehicles at Auto China 2026 (Beijing International Automotive Exhibition)

Aisin Corporation, together with the luxury car brand "LEXUS" and the beauty brand "ReFa", will exhibit a concept of installing "ReFa HYDRAID" in LEXUS vehicles at "Auto China 2026 (The 19th Beijing International Automotive Exhibition)" held in Beijing, China from April 24 to May 3, 2026. This concept applies our fine water penetration technology, "Hydraid®." Hydraid is the world's first*2 technology capable of generating and emitting the world's smallest*1 water particles by applying the catalytic structure technology used in automotive exhaust gas treatment. In February 2026, we concluded a strategic partnership with MTG to explore new applications for this technology. As an application in the beauty field, we jointly developed the professional beauty device "ReFa HYDRAID." We have demonstrated the effectiveness and application potential of the technology, such as improving treatment quality through its high penetrability into hair. *1 World's smallest: Based on a comparison with commercialized technologies capable of stably generating similar water clusters (published values by major global manufacturers) (According to Stella Associe / November 1, 2025) *2 World's first: As a commercialized technology capable of stably generating water clusters with a particle size of approximately 1nm (nanometer) (According to Stella Associe / November 1, 2025) In recent years, the value of automobiles has evolved beyond a mere means of transportation into a "space" that considers comfort, coziness, and even human well-being. Against this backdrop, we have positioned the advanced technology Hydraid as one of our core technologies, and we are working to expand its potential beyond traditional areas like beauty into the mobility sector. In this exhibition, we apply Aisin's Hydraid technology to the cabin space of a LEXUS, proposing a "healthy mobility experience" that cares not only for the driver but also for passengers. By combining Aisin's Hydraid technology, the BEAUTY LIFE proposed by ReFa, and the high-quality hospitality mobility experience pursued by LEXUS, the three parties aim to realize a new mobility value: "the more you ride, the more beautiful you become." Aisin will continue to work towards realizing its management philosophy, "Inspiring 'movement', bringing smiles to the future," through cross-disciplinary and cross-industry collaboration centered on proprietary technologies like Hydraid. ■ Auto China 2026 Beijing International Automotive Exhibition The Beijing International Motor Show (Auto China), with over 30 years of development since its inception in 1990, is a crucial exhibition event for the domestic and overseas automotive industries.
