Medius Holdings Announces Start of Joint Business by Subsidiary for Medical Material Master Data Standardization

Medius Holdings Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo; Representative Director and President: Yasuhiko Iketani; hereinafter "Medius HD") announces that its subsidiary, MJC Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo), will commence a joint business with Olba Healthcare Holdings Co., Ltd. (Headquarters: Okayama-shi, Okayama) from July 2026, aiming to standardize medical material master data.

1. Purpose of Commencing the Business
Currently, medical devices and materials used in clinical settings are becoming increasingly sophisticated and diverse, leading to an enormous and complex volume of product information provided by manufacturers. On the other hand, the management systems introduced by medical device wholesalers and individual medical institutions are optimized independently, requiring manual input for each system when registering product information. As a result, the entire medical industry not only incurs unnecessary costs such as personnel expenses due to duplicate input but also faces situations where delays in information registration impede the entire supply chain. Furthermore, with the recent decline in the working population, securing personnel to handle data entry tasks has become extremely difficult, and this trend is expected to continue.
From the above, we have determined that centralizing and standardizing data management operations as an infrastructure is necessary for the sustainable development of the entire industry. Through this business, we will promote the standardization of master data, contributing to the reduction of administrative burdens in the medical industry and the maintenance and improvement of a higher quality medical care provision system. This business will be jointly executed by Medius Solution Co., Ltd., which operates a medical material master data business within our group, and Hosnet Japan Co., Ltd., a consolidated subsidiary of Olba Healthcare Holdings Co., Ltd. with a proven track record in the same field.
