Company Profile

Dreams evolve infinitely.

Since our founding, the times have changed drastically, but based on the wealth of knowledge gained from past experience and advanced technological capabilities, we have maintained the philosophy that “a company is made up of people” and have continued to develop to this day. It’s done. In the information age, which is constantly advancing and developing, we will continue to strive to respond quickly and flexibly to a wide variety of customer needs, and to continue to improve our skills. In order to always put the customer first and to establish and maintain a quality system to ship products that meet customer needs, we have acquired and maintained world-class international standards such as ISO9001 and ISO14001. In addition, all of our executives and employees will work hard to become a company that can contribute to society as much as possible based on the principle of coexistence with the local community.

Greeting

Our company was founded in 1978 by my father, Masaaki Ikeda, and with the motto of “cherishing playfulness,” we have strived to create products with all our might.
I believe that the ideas that are created through manufacturing are limitless. I want to create products that I want to own. We will continue to evolve as we all share this feeling.
Our company also has a factory in the Philippines, and we work with many colleagues across nationalities. Even if there are differences in national style and culture, if you can communicate your feelings and thoughts, you can overcome any difficulties.
I will continue to value my many colleagues and new encounters, share our feelings together, and promote endless improvements in the workplace, aiming to be a company that continues to the next generation and the next generation.
