Japan's Electronic Signature and Certification Business Act (ESCBA), enacted in 2000, provides the legal framework for electronic signatures. Under Article 3, an electromagnetic record that has been signed with an electronic signature is presumed to have been established authentically — meaning the signature carries the same legal presumption as a seal (hanko) or handwritten signature.

Japan's Electronic Signature and Certification Business Act (ESCBA), enacted in 2000, provides the legal framework for electronic signatures. Under Article 3, an electromagnetic record that has been signed with an electronic signature is presumed to have been established authentically — meaning the signature carries the same legal presumption as a seal (hanko) or handwritten signature. The ESCBA defines an electronic signature as any measure taken by electronic means to indicate that the information was created by a specific person. Japan's legal system traditionally relied heavily on personal seals (hanko/inkan), but the COVID-19 pandemic accelerated the adoption of electronic signatures, with the government actively promoting digital transformation. SignForge meets ESCBA requirements through its signer identification system, cryptographic integrity verification, and comprehensive audit trail.
