Honorary Chairman of the Board

Riichiro Nakamura​

Representative director of Nakamura-Gumi Co., Ltd., founder of NTI, Inc.

After graduating from the Department of Civil Engineering at Ritsumeikan University, he joined the Nakamura-Gumi. Since then, he has been engaged in the development and maintenance of regional infrastructure as a local general contractor in the northern part of Mie Prefecture for more than 60 years.

Since ancient times, the excavation method of open digging and burying method from the ground has been used for laying sewerage.

However, since nearly half a century ago, open digging method has become difficult in densely populated areas, traffic concentration areas, or crossing areas of railways and roads, and tunnel method has been required.  For the construction of small-diameter tunnels where people cannot work in the pipe due to the small-diameter, he jointly developed a semi-shield method (Robot Jacking method) that performs semi-automatic excavation and semi-automatic surveying and spread it to the world.  To date, it has succeeded in laying curves, long-distance laying, and non-ferrous pipes, and has contributed to achieving the world's highest sewerage penetration rate in Japan.
