I am NJ, the representative of HCS. After graduating from university, I joined an automobile manufacturer and later spent over 20 years at Mugen (and M-TEC). Until recently, I was also part of the second official goods company affiliated with a certain automobile manufacturer. In 2023, I ventured out on my own and established HCS. At Mugen, I was responsible for parts and accessories, vehicle planning and development, special projects, both domestic and international liaison work, and various collaborations with Honda. One of the most memorable experiences was launching the first complete car as Mugen. Reflecting on those times, I have compiled some development stories.
