About this network

CKP is the Cyber Kansai Project, a non-profit consortium in Japan's Kansai region (Osaka, Kyoto, Kobe) formed to promote internet technology and its transfer into regional business use.

What it's used for

• Network infrastructure for the consortium and its member organisations.
• Testbed and common-platform work for network applications, in line with the project's stated goal of building shared foundations for business use of the internet.

Notable

• The project's registered contact sits in an academic lab at Kyoto Sangyo University, reflecting its university-plus-industry membership rather than a commercial ISP structure.
• The address footprint is small: this is a consortium's own network, not an access provider selling connectivity at scale.
