CloudSign, operated by Bengo4.com, is one of the most widely adopted electronic signature platforms in Japan, used by businesses and government agencies alike. It covers the full contract lifecycle, from PDF signing and approval workflows to AI-powered document management.

Recipients can sign via a simple email link without creating an account, making it easy to get routine agreements done quickly.

By default, CloudSign applies email verification, activity logs, and timestamps to every signature, meeting the requirements of Japan’s Electronic Signature Act.

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

A free plan is available for small teams to get started with basic contract sending and signing.

Signing screens and email notifications are available in English and Chinese (simplified and traditional), while the admin dashboard stays mainly in Japanese.
