CEO Message


More than 20 years have passed since the introduction of surgical assisting robots, and the use of robots is spreading in Japan and internationally.
We started the research on surgical assisting robots at the Tokyo Institute of Technology in 2003. We succeeded in the development of a pneumatically driven surgical assisting robot prototype that can control force like a human.
It had combined the need for force feedback, which had already been demanded at the time, with the seeds for air pressure measurement and control technology in our laboratory.
With the support of many people, we started Riverfield Inc. with the hope that the results of our research would impact beyond research, and would help the medical community.

Riverfield will make the most of our medical robot technology and our accumulated experience through the development to date to achieve a society where everyone, regardless of region, can receive advanced, safe, and secure medical care.
We would also like to create new value in a wide range of fields beyond medical care, with the hope to share surprise and joy through creating new products that will make everyone excited.
And to actualize our goals, we will continue our efforts to implement new technologies in society with a challenging and never-give-up mentality.

We look forward to your continued support.

We had recognized the importance of the transfer of technology to business, but it was difficult in the medical device industry due to high risks.
Therefore, we started my own company with the aim of creating a company that is unique to a university-born venture, with a strong emphasis on fairness and publicity.

Based on the results of many years of research at the Tokyo Institute of Technology and Tokyo Medical and Dental University, we intend to contribute to solving a wide range of social issues in the field of robotics, with a focus on medical devices that require high safety.

We look forward to your continued support and encouragement.
