WAN-Sign, provided by NX Wanbishi Archives (part of the Nippon Express Group), is a Japanese e-signature and contract management platform built for security-conscious organizations. It holds internationally recognized security and privacy certifications.

Recipients can sign via email verification without creating an account, keeping the process straightforward for routine agreements.

WAN-Sign offers certificate-based signing, email-based signing, or a mix of both, meeting the requirements of Japan’s Electronic Signature Act.

The service starts with no initial or monthly base fees, with a free allowance for sending contracts each month. Costs scale based on storage volume.

The platform includes approval workflows, templates, hanko-style visual seals, and a patented feature for managing both paper and digital contracts in one place. Paper contract scanning and physical storage at NX Wanbishi Archives’ facilities are also available.

WAN-Sign supports bilingual operation in Japanese and English, covering the admin dashboard, signing screens, and notification emails.
