Management policies

"We will continue to serve as the core of our customers' production activities."

It would be difficult to respond to today's diversifying and complicated market armed with only a unilateral perspective. We believe that we need to offer our customers new opportunities by incorporating their requests into products and by adding extra value. Our ideal trading company would constantly stand some steps ahead of customers, fully understanding market needs so that it could bolster the competitiveness of its customers without interruption. It would be capable of making proposals that cover the challenges that customers should address at the moment, the overall cost of production, speed, sales and support after production and of carrying them out. We start by entering into comprehensive discussions with customers until both of us are satisfied. This enables us to join with our customers in taking on the challenge together in the global market.

"We will continue to be a significant player in the community."

We understand that, as we run a business, we need to produce value that is sufficient for our presence to be recognized by society. In the eyes of the community, we must constantly strive to improve, and the community monitors us closely to determine if we can meet this demand. Just because we can satisfy the community's needs today, it does not necessarily mean that we shall be able to do so tomorrow. The details and level of what we are required to do changes a light speed, and present significant challenges for us. To succeed in the years to come, we need to take on these challenges with unswerving courage. We will continue to innovate with a new commitment to success in the coming era.

"We will continue to help our employees to develop their creativity."

Employees form individual elements of the company, which must be a place that allows each of them to work towards their ambitions without anxiety, no matter how high those ambitions might be. If a group is rigid, it will not innovate. Our goal is to provide employees with the opportunity to strive to achieve their dreams of the future instead of looking back on the past. We rely on the positive energy of our staff to drive the company forward. That said, we think it is essential that we do our jobs properly. Words are meaningless without that commitment. We all keep this in mind as we go about our work. We invite you to test the strength of our commitment. It would give you pleasure if you could see how we work. You will surely see our new potential.
