What Osada does

Osada (長田電機工業株式会社, Osada Electric Co., Ltd.) is a family-owned Japanese manufacturer of dental, medical, and veterinary equipment, founded in April 1935 in Shinagawa, Tokyo, with its main production facility at the Nagoya Factory. The company designs and builds a broad portfolio that includes dental treatment units and chairs (flagship Uniauto, Smaily, Opal, Symphony, Pedisia, ST Relux, and Portable Daisy series), dental laser systems (Light Surge, Dio Tron, Nd:YAG), endodontic apex locators (Apex 7/11/15), ultrasonic scalers (Enack 10W/11W), panoramic X-ray systems (Pantoria), digital image management (DDX System / DDX-S2/S3 with iPad viewer), high-pressure steam autoclaves (Creve Tron), and high-speed air turbines (Air Tron, 350,000 rpm). Underlying technology is precision mechanical manufacturing — including CNC turning, 5-axis machining, wire cutting, titanium machining, and in-house spindle production at micron-level tolerances — which is also sold externally as contract precision machining for medical and industrial customers.

The company operates on a custom-made, quotation-based equipment sales model complemented by a recurring after-sales repair and maintenance business, and a B2B contract precision-machining service. Go-to-market is direct enterprise field sales through 22 domestic offices and 11 dental showrooms, supplemented by monthly new-clinic opening seminars, participation in 8+ regional dental shows annually, and digital channels including the OSADA Smart Support app and the ZOOM UP content platform. Distribution outside Japan is handled by OSADA, INC. (Los Angeles) for North and South America, with additional export reach into Europe, the Middle East, Southeast Asia, Oceania, and Africa. In June 2021 the group was reorganized under a new holding company, 株式会社オサダ (Osada Co., Ltd.), consolidating Osada Medical and Osada Service into the main operating entity. The group is led by President Yoshihiro Osada and is privately held with no external institutional investors disclosed; revenue and headcount are not publicly reported.
