Since our formal establishment in Japan in 1956, Sumida has developed and expanded its business with focus on the manufacturing of inductive components such as inductors and transformers. In recent years, our focus in Japan has been on further developing our sales and R&D activities as the majority of our manufacturing has shifted overseas.
Our dedicated teams in this region take the latest developments in technology as well as insights gathered from our customers to ensure that we are continuously developing new innovative products to match the needs of the times.
Our current focus is on developing pioneering products for the rapidly developing segment of automotive-related electronics, as well as for the state-of-the-art medical healthcare and industrial electronics markets.
We deal in products which range in sizes of anywhere from 2mm, to in excess of 20cm and our sales offices and R&D centres are located countrywide for our customers convenience.
