KDDI File Storage is a corporate cloud storage service from KDDI Corporation, offering secure file sharing as an alternative to emailing password-protected ZIP files. It provides two pricing options with no setup fees: a per-user plan for small teams and a capacity-based plan for larger organizations.

Administrators manage user accounts, adjust storage, and change plans from a self-service console. Organizations already using KDDI business services may save by bundling this service with existing KDDI packages.

Active Directory integration connects cloud storage to the organization’s existing Windows login system, giving users a single sign-on experience while administrators manage access centrally.

KDDI provides an English business services site, and the service appears under its global services section.
