OG Electric Medical Equipment Research Institute is founded by the late Chairman Iwao Okuda.

OG completes development of its first product, a low-frequency electrotherapy device, and introduces it to the medical devices market.

OG develops the prototype for Japan’s first motorized intermittent traction device, in collaboration with Professor Kodama from Okayama University Graduate School of Medicine’s Department of Orthopaedic Surgery, and acquires the patent and utility model rights.

Rapid economic growth leads to the popularization of automobiles and a dramatic increase in the number of car accidents. The emergence of whiplash as a societal health problem provides a tailwind for the spread of traction equipment throughout Japan. OG develops Japan’s first motorized intermittent traction device, “Ortho Trac OL-80.”

Striving to extend our expansion beyond the rehabilitation field and make a full-scale entry into the specialty bathing products market, OG completes development of the Liftline Bath HK-101.

OG develops the Chair-In Bath HK-80, allowing users to bathe while sitting in a wheelchair. Meeting customers’ needs, it becomes a hit product.

OG develops the Walk-Through Bath System HK-225/226, significantly reducing the burden on caregivers.

OG develops the Caesas Hydra massage waterbed.

Construction of our new corporate headquarters is completed. Mr. Hiroshi Okuda is appointed Managing Director.

OG develops Volante HK-770, a compact, private bathtub for users who require limited care. Volante is very well-received by various types of medical and elderly care facilities.

OG develops the PAS System, a revolutionary low-frequency electrotherapy device that makes the rehabilitation of post-stroke patients possible.

OG releases Orthrotrac Lasedia OL-6500, a motorized intermittent traction unit that therapists can use for both cervical and lumbar traction.

OG releases Physious FS-350, an electrostimulator that therapists can use for both low-frequency electrotherapy and interferential current therapy.
