Is there an expiration date for the Certificate of Signature？
★ Explanation ★
The process of establishing a company requires a Certificate of Signature issued by an officer of the home country (such as the Notary Public) when a non-resident foreign individual assumes office as the founder of the company.
Under the law, the company’s representative must provide a seal certificate as an attached document when the Company’s Registered Seal is notified to the Legal Affairs Bureau within 3 months after issuance (Article 9-5 paragraph 1 of the Regulation on Commercial Registrations).

The time frame for this seal certificate applies to those issued in Korea and Taiwan, which have also adopted a seal certificate system outside Japan.
Incidentally, for the case of non-resident foreigners who cannot obtain a seal certificate, they can instead submit a Certificate of Signature from their home country issued by the officers of their Notary Public.
At this time, you may use the submitted Certificate of Signature in place of the Seal Certificate that must be created within 3 months as there is no restriction for its validity. But if the address, among other things, shown in the certificate is different from the current one, you must obtain a new certificate again.
When performing the certification procedure of the articles of incorporation in the notary office, it is required to obtain the founder’s seal certificate, oftentimes within 3 months after issuance. This also holds true for those submitting a Certificate of Signature instead.
If you submit a seal certificate that has exceeded 3 months after issuance, it would be better to have prior arrangements with the notary office to prevent any flaws.
