Our transformers are manufactured in Japan, using automatic coil winding machines. Using automatic coil winding machines allows us to reduce labor costs, and to lower the price to the same level as overseas products. Our automated manufacturing process also helps to stabilize the quality of our transformers, and the QA process can be expedited because our products are manufactured in Japan. These products and other electronic parts are handled by dedicated sales representatives who can offer recommendations and desirable solutions for a wide range of products based on customer needs.

Electronic part manufacturing

[Representative's message]
Our company was established in 1974, and we have been dedicated to transformer coil production for over 40 years. We will continue to offer optimal solutions for each customer by expanding our domains. We will apply our skills and know-how as an established transformer manufacturer and the advantages of domestic Japanese production to make impossible solutions possible. We will continue to work hard to support Japan’s Monozukuri craftsmanship. 

[Company structure for market development/overseas expansion]
We hope to participate in exhibitions held by public support organizations, financial institutions, and municipal governments a dozen times a year to cultivate sales channels. We intend to capture issues among exhibition visitors as well as market needs so we can develop the necessary products, or recommend suitable applications for customer needs. We will also review our strengths within our organization in order to recommend possible applications to potential customers in our existing field of business. This is how we intend to establish another pillar of our business.
