The study, which was conducted by J.D. Power Asia Pacific - a global marketing information firm - aims to measure customer satisfaction of telecommunication carriers that provide corporate network services. The study was conducted between August and September 2005 and targeted companies with 100 or more employees. The 2005 study was based on a total of 5,309 responses from 2,992 companies (up to two responses from one company).

IIJ scored much higher than the industry average in five of the six factors that influence total customer satisfaction, including "maintenance services", "global support", "network quality", "sales/account representatives" and "setup process". This gave IIJ the No. 1 position in the study.

As broadband becomes more prevalent and network businesses start to flourish, today's corporate networks and business systems are becoming more reliant on the Internet. At the same time, cyber attacks, viruses, spam, and other Internet threats have become more virulent and have increased the demand for reliable advanced network services among companies. With a foundation of advanced technologies that have been developed since the Company's inception, IIJ has worked to develop new technology and robust services while providing customers with reliable network solutions. IIJ will continue to provide advanced network environments for a broad range of users, and promote innovative Internet technology.
