TOKYO, March 22, 2023 — (Chuo-ku, Tokyo; President: Kensuke Joji; hereinafter “Jolly Good”), in collaboration with Brigham and Women’s Hospital (Boston, Massachusetts, USA; Director: Sunil Eappen; hereinafter “BWH”), a hospital affiliated with Harvard University, develops emergency care VR content. At the same time, Dr. Kei Ouchi, Associate Professor of Medicine at Harvard Medical School, will become a medical advisor to Jolly Good and Jolly Good begins full-scale entry into the U.S. medical market. 

Harvard Medical School is a medical educational institution in North America with a large track record of joint research with corporates and a high awareness of social implementation after research. Therefore, BWH, an affiliated hospital of Harvard Medical School, is the best partner for verifying the educational effects of medical VR and social implementation in North America.

In the future, Jolly Good will develop live-action medical VR in various medical departments under the guidance and supervision of medical advisor Dr. Kei Ouchi and will collaborate with him to verify the educational effects.

Medical VR in North America is mainly CG-based, but production costs are a concern

The size of the medical AR/VR market is expanding every year and is expected to reach 3.9 trillion yen(*) by 2027. The four main categories are medical education, treatment, diagnosis, and rehabilitation.

In the United States, VR technology is implemented in medical education, but most of the VR content is produced using computer graphics, which not only lacks reality, but also requires an enormous amount of time and cost to produce. This makes it difficult to respond to rapidly evolving medical technology and diverse educational needs.

Jolly Good’s medical VR solution enables medical professionals to create their own live-action 360-degree VR images and attracts attention because it provides a more realistic experience than computer graphics and enables mass production of a wide variety of educational content.

“I realized the high quality of technology unique to Japan in Jolly Good’s live-action VR technology and simple remote playback operation technology. Although there are many VR development companies in the U.S., I thought that the high level of Japanese unique technology could revolutionize medical education in the U.S. and VR medical technology for patients. I would like to make this dream-like goal a reality with my technology and experience.”
