Nihon Kohden Corporation/ADR

Nihon Kohden was founded in 1951 by Yoshio Ogino as a manufacturer of EEG machines, a niche it dominated in Japan by the 1960s. The company went public on the Tokyo Stock Exchange in 1970 and later established an American Depositary Receipt program. Today it generates most of its revenue from patient monitors, defibrillators, and neurodiagnostic devices sold to hospitals globally. The company's core market is acute-care hospital equipment: patient monitoring systems (EEG, ECG, vital signs), defibrillators, and ventilators. It also produces clinical information systems and point-of-care testing devices. Geographic revenue splits roughly 60% Japan, 25% Americas, 10% Europe, and 5% rest of Asia. Confirmed hospital customers include major Japanese academic medical centers and US hospital chains. Nihon Kohden employs roughly 7,500 people worldwide. The company operates R&D centers in Tokyo and San Diego. Its ADR trades on the OTCQX market under ticker NHKDY. In March 2023, the company launched a new remote patient monitoring platform for post-acute care settings. What distinguishes Nihon Kohden from pure-play medical device firms is its vertically integrated manufacturing of both hardware and proprietary software for clinical information systems, allowing it to sell complete monitoring ecosystems rather than standalone devices.
