Message from the CEOMessage

Kotobuki Densetsu Co.Ltd. was founded in 1976.

When my father started the company, he began by installing rotary dial phones. While observing this business and experiencing a time of great economic, scientific, and technological development, I thought to myself, "Since I was born on the earth, I want to do business on a global scale!" With this in mind, I took over my father's business and have been striving to expand and develop our business world wide.

It has been 48 years since the company was founded, and during this time, information and communication technologies have developed dramatically in our society. We have kept pace with these advances through continuous technological innovation, and have now grown into a diversified business that includes not only wiring and electrical installation work, but also IT infrastructure construction and temporary staffing services.

Blessed with good coworkers, we were able to expand our business beyond Kyoto and Osaka to Tokyo with a small number of employees, and then to the Tokai (Nagoya) region, which was the dream of my grandfather, who was killed in World War II, and successfully established a service network spanning Tokyo, Nagoya, and Osaka.

Hence, my next target is to take on the challenge of my aforementioned long-cherished desire to enter the global scene. In addition to inbound companies from various countries entering the Japanese market, we are also engaged in the telecommunications and electrical installation business at the heart of facilities that are in demand on a global scale, such as data centers. Moreover, we will continue to take on new challenges as long as our technology continues to be used in a wide range of fields, such as supporting Japanese companies that are expanding their business to the world.
