Tsukaeru File Box is a cloud storage service from Tsukaeru.net Inc., designed for small and medium businesses looking to replace local file servers. It works directly from Windows Explorer and Mac Finder with drag-and-drop, and has no file size limits on uploads. The service runs from an ISO-certified data center in Nagano Prefecture.

The platform keeps a full version history and can recover deleted files. If ransomware strikes, bulk file recovery restores everything at once. An Advanced plan adds login restrictions by IP address, device management, and access from Linux systems.

Pricing is based on storage capacity with no per-user fees, so teams can grow freely without extra costs. All capacity-based plans allow unlimited users.

Active Directory integration connects cloud storage to the organization’s Windows login system, so IT teams can manage all user access from one place.

Both the interface and support are available in English, with year-round emergency help by phone, chat, and email.
