The original company was established in 1951 under their former name of the Kokusai Kyouti Kougyo Co. and was renamed in 1957 as the Yamato Motor Co. It currently employs 130 staff.

     When the motor boat racing law was then introduced, they developed the first Japanese made racing motor based a Mercury design and have, ever since, been producing about 1,700 motor boats, propellers and engines per year for the pari-mutuel motor boat race.
