CTO Message

Implement technology into society and move the world forward

To realize SoftBank’s corporate philosophy, “Information Revolution – Happiness for everyone,” we conduct R&D to create new technologies and services, and implement them into society.

Bringing new ideas to life is very challenging and difficult. That is why we believe it is important to not fear failure, to learn from past failures and continue to take action.

Today's challenge will be tomorrow’s normal. I believe that we can significantly change society with one technology. With our researchers, driven by their belief in the power of technology, we will continue to create a future driven by innovation that changes the world.
