Thank you for your continued support of our secure file transfer platform, "Kozutumi."
We are thrilled to announce that , 2026, the number of companies using Kozutumi has officially surpassed 3,000!
Since our official launch in November 2022, we have reached this major milestone thanks to the incredible support of our users. The entire Kozutumi team would like to express our deepest gratitude to everyone who has supported and trusted our service.
■ Background and Our Journey
- The Necessity of Shifting Away from PPAP: Initiatives to eliminate "PPAP" (the practice of sending password-protected ZIP files via email) to prevent malware and data leaks have become essential for companies of all sizes.
- Why Users Choose Kozutumi: Kozutumi has been highly rated by many companies for its ease of use—allowing secure file exchanges with external partners without requiring them to log in—while ensuring robust security features such as virus scanning and timestamps.
■ Recent Feature Enhancements
- Release of the "Archive Option for Audit": Most recently, in February 2026, we released a new feature that permanently stores all sent and received files to enhance corporate compliance, continuously updating our platform to better protect your business.
We remain committed to improving our product and enhancing our services so that you can exchange important files "more easily and more securely."
Thank you for your continued support of Kozutumi.
