Overview
MedicalNote, Inc. (株式会社メディカルノート) is a Japanese healthcare technology company headquartered in Minato, Tokyo.

"Medical Note" is a medical information media platform launched in March 2015, featuring content supervised by over 2,400 physicians and medical professionals. It covers 2,139 diseases as of May 2020, including many rare and intractable diseases often overlooked by major sites. "Medical Note Medical Consultation" is an online medical consultation service connecting users with healthcare professionals, including specialists. "Hospital Manager," launched in October 2020, is a SaaS tool for medical institutions supporting digital transformation (DX), offering web reservations, pre-consultation questionnaires, video calls/online medical treatment, and payments in one stop. MedicalNote has established partnerships with major organizations including Aflac (2017), Bangkok Hospital (2018), Yahoo! Search (2018), Tokio Marine Holdings (2019), and Google (2020). It has also formed business alliances with medical associations and institutions such as the Japan Cancer Society. Notable advisors include Dr. Fumimaro Takaku, former president of the Japan Medical Association, as special advisor, and Dr. Yoshitake Yokokura, honorary president of the World Medical Association and Japan Medical Association, as medical advisor. The company raised 250 million yen from JAFCO in July 2015 and has received capital and business alliances from Tokio Marine Holdings. Its online consultation service has been adopted as a employee benefit by companies such as Benesse Holdings, Mercari, and UUUM. MedicalNote continues to expand its platform to support patients, medical institutions, and corporations in Japan.
History
MedicalNote, Inc. was established on October 30, 2014, in Minato, Tokyo, by Yuma Umeda, an angel investor, and Sho Inoue, a physician whose research focused on medical education and communication. The founding was inspired by Umeda's personal experience with medical challenges and the lack of reliable medical information outside hospitals. With the vision of "connecting doctors and patients," the company began collaborating with over 2,400 physicians and medical professionals to disseminate information originating from medical practice. In March 2015, the company launched its medical information media platform, "Medical Note." The platform's content is entirely supervised by physicians and medical professionals, covering 2,139 diseases as of May 2020, including many rare and intractable diseases that are not featured on major websites. In July 2015, MedicalNote raised 250 million yen from JAFCO. The company expanded its partnerships and services over the following years. In May 2017, it formed a business alliance with Aflac. In March 2018, it partnered with Bangkok Hospital, and in June 2018, it collaborated with Yahoo! Search to provide disease information in search results. In October 2018, it partnered with a medical information site in Yokohama, Kanagawa. In November 2018, Dr. Fumimaro Takaku, former president of the Japan Medical Association, became a special advisor. In February 2019, MedicalNote launched a smartphone app version of "Medical Note." In March 2019, a former desk editor of the Mainichi Shimbun's "Medical Premier" became editor-in-chief. In June 2019, the company entered a capital and business alliance with Tokio Marine Holdings. In 2020, MedicalNote responded to the COVID-19 pandemic by opening a special page "Now, doctors want to deliver: Latest information on COVID-19" in April. In July 2020, it began an initiative with Google to support access to medical information. In October 2020, it launched "Hospital Manager," a web reservation and management system to support DX for medical institutions. In November 2020, Dr. Yoshitake Yokokura, honorary president of the World Medical Association and Japan Medical Association, became an advisor. The company also operates "Medical Note Medical Consultation," an online medical consultation service that connects users with healthcare professionals, including specialists. This service has been adopted as an employee benefit by companies such as Benesse Holdings, Mercari, and UUUM, and has partnerships with Aflac, Tokio Marine & Nichido, and Euglena.
