Corporate Philosophy

“Addressing client needs with integrity.”
For this ultimate goal, RSI undertakes projects with a sense of commitment and expertise, and this is why we are determined to deliver consistent quality services to our clients.
Because all RSI consultants share and believe these principles, we are able to propose solutions and support, always thinking of what is best for our clients, and this enables us to promise success.

Message from the President

In an ever-changing IT environment, especially in recent years, it is crucial for businesses to keep up with advanced technologies.

Since RSI was first established as an independent consultancy firm in 2006, we have built up our expertise working on various data center projects with clients in Japan and abroad, always making sure to incorporate cutting-edge trends. RSI has been successful not only in the difficult task of acting as coordinator between IT and facilities, but also as a solution provider even for sophisticated demands from overseas, and we will continue to build on our strengths and provide high quality consulting services focused on data centers.

“With integrity” is a principle we have adhered to since our beginnings, and our first and foremost goal as professionals has always been to provide the best solutions to meet client needs.

Thus, we will continue to strive to provide swift and optimal advice and solutions to address various issues that may occur in our clients’ projects and daily operations, so that we may enjoy a mutually successful future together.
