Contrea

Contrea, Inc. is a Japanese healthcare technology company founded in January 2020 by Kazuhiro Kawabata and headquartered in Shinjuku-ku, Tokyo. The company develops and operates MediOS, an end-to-end patient digital transformation platform that streamlines communication, administrative procedures, and information exchange between medical professionals and patients. MediOS integrates patient intake questionnaires, e-consent forms, doctor/nurse explanation support (via animated video modules), secure messaging, and post-hospitalization follow-up into a unified digital workflow. The platform is designed to reduce the administrative burden on healthcare providers — particularly around informed consent and paperwork — while improving the patient experience. Contrea's mission is to ensure peace of mind for everyone involved in healthcare. The company has received investment from Global Brain via the Meiji Yasuda Future Innovation Fund.
