Uetax Corporation

Uetax Corporation is a Japanese company based in Jōetsu, Niigata Prefecture, specializing in underwater acoustic technology and waterproof audio equipment. The company's name is an acronym derived from "Underwater Electronics Technology Acoustic," reflecting its core focus. Founded in 1986 by Masataka Ueki, the company began by developing equipment for artistic swimming (synchronized swimming), which required underwater speakers for Olympic competitions. Over the decades, Uetax has expanded its expertise into marine science, aquaculture, scuba diving, and various industrial applications. Its product lineup includes underwater speakers and dedicated amplifiers, underwater microphones, waterproof microphones, waterproof vibration speakers, special speakers, diving equipment, rescue equipment, and electronic devices. The company also offers contract manufacturing services (OEM/ODM) leveraging its precision machining and electronics capabilities. Uetax's technology has evolved from initial depth ratings of around 20 meters to over 100 meters, and its products are used in medical, environmental, fisheries, sports, and automotive fields. The company is known for its five core technologies: waterproofing, underwater technology, underwater communication, transmission, and precision machining. It has also developed products such as the L-ViC™ air purification device for small air conditioners and the SV-02 single-person underwater communication device. Uetax is a private company, currently led by President Masaharu Ueki. It continues to innovate in underwater acoustics and precision engineering, aiming to contribute to society through advanced technology.

Uetax Corporation was founded in 1986 by Masataka Ueki, who was inspired to create underwater communication devices after encountering underwater acoustics technology while stationed overseas and experiencing scuba diving in the United States in the 1970s. He thought, "If we could talk underwater, it would be more fun," and began developing communication devices. The company name UETAX is an acronym for "Underwater Electronics Technology Acoustic." Initially, Uetax designed equipment for artistic swimming (synchronized swimming), which required underwater speakers for Olympic competitions. The company then found potential in marine science, developing underwater communication, ultrasonic technology, and circuit design. It expanded into fisheries and aquaculture, achieving a dominant share in these fields. Later, it entered the scuba diving market, completing underwater conversation devices through collaborations with the United States and Australia. Over the years, Uetax improved its products' depth ratings from about 20 meters to over 100 meters by developing innovative acoustic vibration methods and special diaphragms. The company also applied its precision machining technology to computer hard disk drive (HDD) components, developing automated equipment, inspection devices, and measurement devices, and increasing spindle speeds from 1000 rpm to 5800-7800 rpm. Today, Uetax continues to provide underwater acoustic equipment, waterproof microphones and speakers, and OEM/ODM services, leveraging its five core technologies: waterproofing, underwater technology, underwater communication, transmission, and machining. The company is currently led by Representative Director Masaharu Ueki.
