About us

Welcome to Maruha Motors Co.,Ltd., the place where japanese quality and precision meet.


Maruha Motors Co.,Ltd. started as a small auto repair shop in 1955. Since then we have been repairing and maintaining all sorts of vehicles.


In the last 57 years Maruha Motors managed to expand its business to car racing and tuning.


The Mazda Roadster, better known as Miata in America and MX-5 in Europe went on sale within Japan in 1989. Maruha Motors is a pioneer in Miata tuning and many fans have offered their support to us.


We have confidence in product development including transmissions, differentials, brakes, suspensions and complicated components such as engine parts.


Year by year more racers and tuners select our products. Thanks to our customers, Maruha Motors has the largest market share of Miata tuning in Japan.


We always seek the best performance, therefore we have been checking engine power with the advanced dyno tester and analyzing our tuning carefully.
