Summary

CSK-IT Management Corporation

Japan · AI-generated

enterprise legacy

CSK — registered to CSK-IT Management Corporation, a Japanese IT services

company from the CSK group.

What it's used for

  • Corporate networking and IT infrastructure / outsourcing services for Japanese business customers.

Notable

  • CSK Corporation, founded in 1968, was one of Japan's major independent software and IT-services houses. It was acquired by Sumitomo Corporation and merged into what is now SCSK Corporation in 2011, so the CSK name survives here mainly as a registry artifact.
  • The registration has not been substantially refreshed in many years; treat the organisation name as historical and the space as enterprise IT infrastructure.
