Background
Our vision is “Going for ZERO, Preventive Care for the Health of Society”. To achieve this vision, we globally develop and provide medical devices and services that contribute to the early detection, prevention of severe progression, and recurrence prevention of cardiovascular diseases. Our cardiovascular business is strengthened by the technological expertise cultivated since the launch of our first blood pressure monitor in 1973, and the insights gained through collaboration with numerous physicians and academic societies. Today, we provide products and services to more than 130 countries and regions worldwide.
Matsuya R&D develops, manufactures, and sells automated sewing machines, as well as various sewn products produced using its proprietary automated sewing technology. The company’s strength lies in production lines equipped with its high-performance sewing machines, ensuring a stable supply of high-quality sewn products. Among these are the cuffs* used in our blood pressure monitors.

Purpose of Making a Wholly Owned Subsidiary
By making Matsuya R&D a wholly owned subsidiary, we believe we can achieve greater synergies by sharing management resources and jointly advancing projects. This will enable us to enhance the quality of blood pressure cuffs—a critical factor in the accuracy and quality of blood pressure monitors—strengthen our competitiveness in the intensifying global blood pressure monitor market, and accelerate the development of new products.
We determined that making it a wholly owned subsidiary and advancing measures for corporate growth is the optimal approach to flexibly and proactively promote initiatives that will enhance the competitiveness and profitability of both companies over the medium to long term.
