E-signature legality · Asia-Pacific
Is electronic signature legal in Japan?
Yes. Most Japanese contracts can be concluded without any formality, so e-signature platforms are widely used by businesses. The Ministry of Justice has confirmed that cloud-based signatures by a service provider can qualify for the statutory presumption of authenticity.
The law
- Act on Electronic Signatures and Certification Business (2000)
- Civil Code, art. 522(2) — contracts need no particular form unless the law says otherwise
What still needs wet ink, a notary or a qualified signature
- Certain contracts that must be in writing or notarised, such as fixed-term land leases for business use
- Wills
Where Clinch fits
Clinch is built for everyday commercial agreements — freelance and agency contracts, statements of work, NDAs, quotes and service agreements — which in Japanneed no special form. Every signature is captured with the signer's explicit consent, and the signed PDF carries an audit trail (name, email, timestamp of every event, hashed IP) plus a SHA-256 fingerprint of the exact document, so anyone can check it was not changed after signing.
It is a simple electronic signature, not a qualified one: for the documents listed above, use the formality the law requires.
