“Inkan” in English is referred to as a “hanko” or a “seal.” It is a specialized stamp used in Japan and some other countries to certify identity or consent. Typically, hankos are made of wood or ivory and have a cylindrical shape to create circular impressions. However, in recent times, plastic or metal hankos have become more common.
In Japan, hankos are often required for legal documents, contracts, and official procedures. Individuals typically possess a personal seal called “jitsuin,” which is considered crucial for verifying one’s identity. Additionally, corporations and organizations have hankos such as “ginkoin” (bank seals) or “kaishain” (company seals) used by their representatives.
Hankos serve as important means to identify their owners and are utilized by individuals with authority and responsibilities to authenticate their identity.
