We
have been developing electrical products since 1953, when we developed
a selenium rectifier for motorcycles. Since then, we have centered
on development and sales of regulators/rectifiers and CDIs (capacitor
discharge igniters) for motorcycles. We have also expanded
to develop universal engine transistor-magnets, engine generator
AVRs, governor devices, and more to fit the needs of the times.
Recently, we have been developing and mass-producing high-efficiency
step-down DC/DC converters for HVs and FCVs. Also, we have
been developing ECUs (engine control units) for idle reduction
in motorcycles. Thus, we have been very active in the field
of environmentally friendly products.

Our electrical products implement an integration
of core technologies such as vehicle equipment technology and power
circuit technology that we have polished over many years. They make
wide use of power semiconductors of our own manufacture which are
highly reliable and highly efficient.
The manufacturing know-how and management techniques that have undergirded
our development and production of electrical products for motorcycles
and automobiles are being utilized in production bases throughout
Asia as we expand. We are supplying goods to global markets with
high-level QCDS (quality, cost, delivery, and service).


Our universal engine electrical products are combined with universal standalone engines and installed in string trimmers, pumps, lawnmowers, snow blowers, generators, etc. We put great effort into the development of eco-friendly inverters that curb the energy consumption of generators and such proportional to the external load fluctuation to the minimum, with the spotlight on our sine wave inverter, which converts the AC voltage from the rotational energy of a generator to quality commercial voltage.
