Optage Inc.

OPTAGE INC. is a Japanese telecommunications and digital-infrastructure company within the Kansai Electric Power Group; its corporate profile lists establishment on April 2, 1988. Public materials describe it as providing connectivity services (including the “eo Hikari” brand referenced in group reporting), while some third-party profiles emphasize wired telecommunications activity.

Routing registries and BGP monitors associate OPTAGE INC. with AS17511 (and also AS9358), showing a Japan-based backbone with many advertised prefixes and observed interconnections. A public PeeringDB entry exists for AS17511, indicating active peering disclosure, though some contact fields are restricted to logged-in users.

Public “reviews” are fragmented and often context-specific (e.g., employer-review pages rather than ISP service quality), and there is not enough consistent end-user feedback in open sources to form a strong consensus; overall signal looks mixed-to-neutral.
