Shachihata Cloud eSign, part of the Shachihata Cloud family offered by Shachihata Inc., combines traditional hanko-style stamp imagery with modern e-signature and document approval workflows. It targets organizations transitioning from paper-based seals to digital processes.

The platform supports Advanced Electronic Signatures in compliance with Japan’s Act on Electronic Signatures and Certification Business, with timestamps, audit trails, and legally valid signing.

Shachihata e-Sign integrates e-stamp visuals directly into the workflow for visual continuity with traditional seals, while enabling cryptographic signing behind the scenes for legal validity. It features configurable approval chains, document circulation, full-text search, folder management, business chat integration, and CSV export.

The solution is available in Japanese only and is tailored for domestic corporate and public-sector needs, aligning well with existing hanko-based practices.
