GMO Sign, by GMO GlobalSign Holdings, is a cloud-based e-signature and contract management platform widely used by businesses and local governments in Japan. It handles PDF signing, approval workflows with templates, and secure document storage.

Recipients can sign contracts via a simple email link without needing an account, keeping the process quick for everyday agreements.

GMO Sign adds email or PIN verification, activity logs, and timestamps to signatures, meeting the requirements of Japan’s Electronic Signature Act.

For contracts that need the strongest legal standing, GMO Sign lets signers verify their identity with a MyNumber card.

A free plan lets teams try the service with basic contract sending before committing to a paid tier.
