Representative's Message

We established Tozai Sogo with the aim of developing business between Japan and China, East and West, and through Japan-China friendship. One of these businesses is designing, repairing, modifying, and selling peripherals for semiconductor equipment. We have applied the high-frequency technology we have cultivated over the years to the repair of high-frequency power supplies and matching boxes used in semiconductor manufacturing equipment. Rather than repairing according to the manual, our strength is in making improvements while fixing by analyzing the internal electronic circuits and modifying them to improve performance. In addition, we have a relationship of trust with our peers in China and Taiwan, and their cooperation enables us to work on repairs otherwise not possible in Japan. Tozai Sogo will continue to provide services in the semiconductor equipment field with customer satisfaction as our top priority.
