We are a global medical device design innovation firm. We realize ideas in a solid and efficient manner. Since our founding, zenius has collaborated with numerous leading European medical device manufacturers, particularly in the field of DDS (Drug Delivery Systems), to support development. In doing so, we have come to recognize that while Japan's manufacturing technology and quality, capable of turning advanced designs into products, are highly regarded, there are few medical devices originating from Japan that leverage these strengths. In fact, much of the Japanese medical device market relies on imports, and we strongly feel that there is an increasing need for domestic medical device development based on Japanese insights and human factors. From front-end innovation to mass production. With over 10 years of experience in global development, we will contribute to Japanese medical device development with our capabilities specialized in medical device development.
