A Tokyo-based automotive diagnostic equipment distributor providing workshops and vehicle owners with professional-grade tools since 2014.
Diagnostic Auto Scan Co., Ltd. was established in 2014 in Shinjuku, Tokyo, with a focus on supplying professional automotive diagnostic equipment to repair workshops, dealerships, and individual vehicle owners across Japan and the wider Asia-Pacific region.
