What Are Hanko Stamps?
A Hanko is a carved stamp that has your last name on it in kanji characters. The Hanko (also known as Inkan) is much more than a simple stamp—it is a legally recognised signature used in many aspects of daily life.
The History of Hanko Stamps
The use dates back to ancient China, where carved seals were used by emperors and officials to authorise documents. This practice spread to Japan around the eighth century, where it quickly became integrated into the cultural and administrative framework. Originally reserved for the ruling classes, they eventually became accessible to the general population. Today, Hanko stamps are used by almost every citizen and business in Japan.
What Are Hanko Stamps Used For?
While most Western countries rely on handwritten signatures, Japan uses Hanko stamps for a wide range of personal, legal and business transactions. Some of the most common uses include:
- Official Documents
These Japanese stamps are used to authorise contracts, legal agreements and government forms. Whether opening a bank account or signing a lease, a Hanko stamp is often required. - Business Transactions
Companies in Japan use specially registered Hanko stamps known as Jitsuin for official corporate agreements, invoices and internal approvals. - Personal Use
Individuals often have personal Hanko stamps, known as Mitome-in, used for everyday activities such as receiving packages or confirming attendance at meetings. - Ceremonial and Cultural Significance
Hanko stamps also play a role in calligraphy, art and gift-giving. Artists use them to mark their work, adding authenticity and personal identity.

Materials and Craftsmanship
Traditional Hanko stamps are often made from wood, ivory or stone, while modern versions may be produced from plastic or metal. Each stamp is uniquely carved with the owner’s name or business identity in Kanji, Katakana or Roman characters, making them highly personalised items.
Are Hanko Stamps Still Relevant Today?
With the rise of digital signatures and online transactions, there has been some debate about the continued relevance of Hanko stamps in Japan. Some businesses and government departments have begun modernising their processes, but Hanko stamps continue to hold symbolic and practical importance.
In 2025, a Hanko stamp could be used for loyalty stamping for small businesses, branding packaging or craft projects such as card making. Finding new modern day uses is a great way of keeping the tradition alive whilst moving with the times.
