'ALOKA, the innovator in ultrasound is the longest operating ultrasound company in the world with its main headquarters located in Tokyo, Japan.
The history of ALOKA began in 1950 when the medical equipment department of Japan Radio Company became the independent company, Medical and Physical Institute Co., Ltd.
In 1960, we developed the world's first commercially available diagnostic ultrasound system.
In 1976, our company name changed to ALOKA, which, in ancient Sanskrit, means 'Ray of Hope'.
ALOKA's ultrasound systems have been sold in the United States through distributors since the early 70s. Some of our major distributors included Johnson & Johnson Ultrasound and Corometrics Medical Systems, Inc., which also provided service for the ALOKA equipment.
In 1986 the first ALOKA office was opened in the United States.
And on January 1, 1991, ALOKA America began direct sales of ultrasound units.
All US sales, distribution and service are provided through our US headquarters located in Wallingford, Connecticut . In addition, we have sales, service and clinical applications representatives strategically located throughout the country to provide exceptional service to our customers.'

In November 2010 Hitachi Medical announced the acquisition of ALOKA.
