In Japan, the use of hanko (判子) or inkan (印鑑) is deeply embedded in both personal and corporate practices. For businesses, possessing a corporate hanko is not merely a formality but a legal necessity. These seals serve as official signatures, authenticating documents and signifying company approval.
Understanding Corporate Hanko
A corporate hanko is a seal that represents a company in official capacities. Unlike personal seals, corporate hanko are used to endorse company decisions, authorize transactions, and formalize agreements. They are essential for:
- Company Registration: Required during the incorporation process.
- Banking Transactions: Opening corporate bank accounts and authorizing financial operations.
- Contracts and Agreements: Validating business contracts, leases, and other legal documents.
- Internal Approvals: Endorsing internal documents and decisions.
The presence of a corporate hanko on a document signifies the company’s commitment and agreement to the contents therein.
Types of Corporate Hanko
Japanese companies typically utilize several types of hanko, each serving distinct purposes:
1. Representative Seal (Daihyo-in)

- Shape: Round.
- Usage: This is the most critical seal, registered with the Legal Affairs Bureau. It’s used for significant legal documents, including company registration, major contracts, and official filings.
- Significance: Represents the company’s legal authority.
2. Bank Seal (Ginko-in)

- Shape: Round or square.
- Usage: Specifically used for banking purposes, such as opening accounts and authorizing transactions.
- Significance: Ensures financial documents are authenticated by the company.
3. Company Seal (Kaku-in)

Each seal plays a unique role in the company’s operations, ensuring that documents are appropriately authenticated based on their importance.
Importance of Corporate Hanko
In Japanese business culture, the hanko is more than a stamp; it’s a symbol of trust and authenticity. The use of hanko:
- Establishes Legitimacy: Documents bearing the corporate hanko are considered official and legally binding.
- Ensures Accountability: The use of specific seals for different purposes helps delineate responsibilities within the company.
- Facilitates Operations: Streamlines processes by providing a standardized method of approval.
While digital signatures are gaining traction, the hanko remains a cornerstone of Japanese corporate operations.
Obtaining a Corporate Hanko
Acquiring a corporate hanko involves several steps:
- Design Selection: Choose the appropriate seal types (Representative, Bank, Company) based on your business needs.
- Material Choice: Select materials like wood, horn, or titanium, considering durability and formality.
- Engraving: Have the company name and other relevant details engraved in the chosen script style.
- Registration: Register the Representative Seal with the Legal Affairs Bureau to obtain legal recognition.
It’s advisable to consult with professionals or specialized services to ensure compliance with legal requirements.
Maintaining and Securing Corporate Hanko
Given their legal significance, corporate hanko should be:
- Stored Securely: Keep in a locked and restricted-access location.
- Handled Responsibly: Limit usage to authorized personnel to prevent misuse.

Implementing strict protocols around hanko usage safeguards the company’s legal and financial interests.
