Corporate Profile


Representative Director Toshitaka Yokokura

Thank you for visiting JEPS Corporation’s web site.
We are full of “gratitude”.

Since foundation, we have been supported by many customers up until today. We have always been looking for ways to manage a company that makes the customers happy. Our conclusion was: "A customer's satisfaction comes from the staff's satisfaction."

The happiness of enjoying work and providing it to a customer with confidence, is what we strongly believe as "Necessary for this company". We began from "inspection" to "construction", extended further into "management" and established a totalized ground.

My children (the staff of JEPS) are a brilliant group of members. They handle the kind of work in which the result never lies...they’re honest... and hard working. I want each of them to be the kind of person that can be praised, appreciated and thanked by the customers. The kind of person that makes the customers say “I’m glad I entrusted it to you.” We are a still growing company. We will do our best to generate an environment to help customers feel at ease

Management Principle

When you come home and turn the light on, don’t you feel relieved? In the past, there used to be frequent blackouts in Japan, and people were worried and felt uneasy every time the lights went out. When the lights turn back on, people feel relieved and at ease.

We wish to create a heart-comforting environment like that.
To accomplish this, it is important that: "Prevent power off of electricity " "Keep supplying electricity, safely." "Maintain condition which customers can always use it without worry", and this is the "Creation of a Bright, Comfortable and Peaceful Environment" which JEPS is aiming for.
