A Word from the President

President Shintaro Aoki

Our company was founded in 1964 as a manufacturer of road safety products, having been spun off from Azuma Shokai Co., Ltd., which is a company selling road safety products. In the beginning, we mainly dealt in products made of aluminum alloy castings such as safety posts, road studs and markers. Today we develop and manufacture a wide variety of road safety products, including solar-powered road information boards, self-luminous road signs equipped with LEDs, and reflective products.

In consideration of the changing times where we are facing various challenges, such as an aging population with a declining birthrate, natural disasters worse than expected, and the coming autonomous driving society, we will continue understanding the needs of the times. We also have a strong sense of mission as well as a strong desire to improve ourselves to help all people living today and in the future use roads safely and with peace of mind. We will also continue striving to overcome a wide range of challenges in order to manufacture and sell further improved products, including road safety products and renewable energy products, whereby contributing to society.
We are still developing and have much to learn, and would greatly appreciate your continued help and support.
