Business Model

Combined Provision of In-House Developed Network Services and System Integration

IIJ was founded with the vision of spreading Internet a new means of communication in Japan, and began providing Japan's first commercial Internet connectivity service. IIJ established a dominant market position in the Japanese ISP market in the mid-1990s; however, price competition intensified as the number of new entrants increased with the spread of Internet. In such an environment, IIJ Group focused on large-scale enterprises and government agencies that use Internet for their businesses and also developed high value-added network services based on the accumulation of Internet-related technologies in the fields of Internet connectivity, security, Cloud, and mobile services, and provided these services on a monthly basis with its advanced operation capability. Thus, IIJ Group strategically transformed its business model. IIJ Group responds to the diverse network and system demands of enterprises and government agencies by providing a combination of these services and systems integration.

Cross-Selling of In-House Developed Services to Customer Base

The Internet backbone network, which is one of IIJ Group’s strengths, has not experienced any serious failures in about thirty years since its inception, and many of its customers have continued to use its network services over the years. IIJ Group aims to further expand the scale of transactions with them by providing a combination of reliable and high-value-added network services to these customers who have fostered a sense of trust in IIJ Group.

The provision of Internet-related services to customers operating large-scale internal systems has traditionally centered on Internet connectivity and gateway-type services outside of their internal systems. In recent years, large-scale enterprises and government agencies have evolved their systems to ones that combine Internet technologies such as Cloud and remote access based on zero-trust concept with advanced security features. As such, IIJ Group expects demands for its network services and systems integration to increase.
