Message

The growth of individuals drives the growth of a company.

Dialogue connects the world.

We believe that the source of a company's growth lies in its people. The true value lies in individuals growing through their daily work and continuously finding meaning in their existence. No job can be completed by one person or company alone; it requires the support and cooperation of others. Remembering this, respecting each other, and expressing gratitude are essential. This accumulation of actions fosters sincerity and humility, leading to personal growth. And we believe that the growth of each individual supports the growth of the company.

For over 60 years, our Broadcasting Service Center has supported diverse communication venues, including international conferences, academic meetings, and corporate events. Now, we are continuing new challenges to connect the "human power" we have cultivated to even greater possibilities. At this turning point where technological advancements are dramatically changing society, we are working on developing new services, including AI simultaneous interpretation, creating an environment where people around the world can communicate seamlessly, and nurturing the talent that will lead the next generation.

Our goal is not technological advancement itself. It is about people connecting through dialogue, each individual growing, and that growth creating the future of companies and society. Under the philosophy of "Be a valuable presence," we will continue to believe in the potential of people and technology, and strive to be a presence that is essential to society.
