Especially in this age of change,
we believe that trust is our fortune.

The electronics industry has recently grown into a key industry in our country, and we carry a great responsibility as a parts firm in charge of distribution in that industry.

In order to take on this upwardly mobile market in full conscience of this responsibility, we are determined to be:

"A corporation that can contribute to the development and growth of its clients"
"A socially responsible corporation that can take on its role"
"A corporation that can make the dreams of each of its employees come true"

The Japanese economy is now facing a major transition phase that only happens once every ten or so years.
In our industry as well, with the shift of production bases to China due to globalization, increasing strictness of environmental regulations such as the RoHS directive, and the transformation of forms of distribution due to the IT revolution, the very value of our business is being called into question.

To face this age of change and continue to grow along with our clients, we take to heart the fundamental principle of honest management and the fortune of trust our founder built up little by little with vendors. We will overcome every obstacle that might come our way as we progress forward.
