What types of electronic signature are recognized in Japan?
An electronic signature is a measure applied to electromagnetic-record information that (a) indicates the information was created by that person and (b) allows confirmation of whether it has been altered. Japan supports Accredited Certification Businesses (ACBs), whose certificates carry an accreditation mark. An electromagnetic record is presumed authentic where the signature is under the proper sole control of the signer and performed by them; otherwise a challenge may require further evidence (authentication, tamper-evidence, audit log).

Suitable for HR, procurement, corporate resolutions, NDAs, software licensing, healthcare, banking, real estate, lending, insurance, consumer transactions, and many government filings (depending on the document type).
