Management philosophy

Tetsuo Yamaguchi CEO Yamaguchi Electric Ind. Co., Ltd.
There is one significant feature of YEC that stands out from other general automobile parts makers. We are not under the umbrella of a specific automobile maker, which maintains a strong “parts maker-auto maker” relationship. This means that we do not make parts accordingly to the schedule of the new model launches by a specific auto maker.
Instead, YEC is an independent auto parts manufacturer that has its own R&D section for producing its original line of items. Furthermore, we turn those items into sellable, customized products together with our customers in the fields of automobile or construction machinery production, upon acquiring their approval. Our management philosophy is to develop our own brands such as YEC, FLAMMA and TRITON, and deliver our customers products that we have developed originally.
