Hanko: Japan's Name Stamps and When You Need One

In most of the world, you sign your name to confirm something. In Japan, you press a small cylindrical stamp into an ink pad and leave a circular impression on the page. This is the hanko — and for most of Japanese history, it has carried more legal and social weight than a signature ever did.

What is a hanko? A hanko is a small stamp pressed into an ink pad to leave a circular impression, used in Japan where many countries use a signature. There are different types: the mitome-in for everyday use, the ginko-in registered with a bank, and the jitsu-in, the registered seal filed with a municipal office.

Bank accounts, property contracts, marriage registrations, inheritance documents, company approvals — the hanko appears at the significant moments of Japanese life, and at many of the insignificant ones too. Understanding why requires going back a long way, and understanding where it is going requires looking at what has happened very recently.

The Different Types

Not all hanko are equal. Japanese stamp culture has developed distinct categories for different levels of formality and legal consequence.

Mitome-in is the everyday stamp — the one used for signing for a parcel delivery, approving internal office documents, or confirming receipt of something routine. Mass-produced versions are available at convenience stores and hundred-yen shops for common Japanese surnames. The legal weight is limited, but the social expectation of having one is pervasive.

Ginko-in is the stamp registered with a bank when opening an account. It functions as a key: combined with a passbook, it can authorize withdrawals. For this reason, keeping it separate from the mitome-in is standard advice — losing control of a ginko-in registered to an account is a more serious problem than losing an ordinary stamp.

Jitsu-in is the registered seal — the one filed with a municipal office and paired with an official certificate of seal registration. This is what gets used for property purchases, company establishment, inheritance proceedings, and vehicle registration. The jitsu-in and its accompanying certificate together constitute a formal identity verification system. Handling them requires corresponding seriousness.

Corporate stamps follow a parallel structure. Companies maintain a representative seal registered with the Legal Affairs Bureau, a corporate bank stamp, and an angular company seal used for general correspondence and invoicing — each serving a different function in business operations.

Where Hanko Are Required

The range of situations that have historically required a hanko in Japan is extensive enough that carrying one has simply been part of daily life for most adults.

Administrative procedures — change of address registrations, marriage and divorce filings, passport applications, tax returns — have traditionally required stamps. Financial transactions — opening or closing bank accounts, signing loan agreements, entering or exiting insurance contracts — have required them. Property transactions, employment contracts, resignation letters, internal approval documents, expense claims: the list extends through the full range of formal adult activity.

The cumulative effect is that Japanese adults have typically maintained multiple hanko for different purposes, stored separately, treated with varying degrees of care depending on their registered status.

Why Japan Chose the Stamp Over the Signature

The hanko arrived in Japan from China, and records of its use in official documents date to the Nara period in the eighth century. By the Edo period it had spread to general commercial and contractual use among ordinary people. The Meiji era formalized the system, establishing the seal registration framework that connected jitsu-in to official certification and created the identity verification structure that persisted through the twentieth century.

Several factors made the stamp a more natural fit than the signature for Japanese administrative culture. A precisely carved seal produces a consistent impression that is difficult to replicate without the physical object — a different kind of security guarantee than a handwritten name, which varies and can be imitated. Japanese names written in kanji also vary considerably in execution between individuals, making signature standardization less straightforward than in alphabetic writing systems. And once the stamp had been embedded in legal and administrative procedure, its self-reinforcing logic took hold: the system was built around it, which made it indispensable, which justified building more of the system around it.

The Pandemic and the Push to Change

The challenge to hanko culture that had been building quietly for years became a crisis in 2020.

When the government declared a state of emergency and asked people to work from home, a specific absurdity became visible: employees were commuting to offices not to do their work, but to press a stamp onto a piece of paper. The image of workers making the trip specifically for a hanko became a symbol of institutional rigidity at a moment when the costs of that rigidity were suddenly concrete and immediate.

The political response was swift by Japanese standards. Then-minister Taro Kono made hanko abolition a stated priority, and a systematic review of administrative procedures requiring stamps was initiated. By 2021, the majority of government procedures that had required stamps had been revised to make them optional or eliminated the requirement entirely. Electronic signature services accelerated their adoption in the business sector. The direction of change became unmistakable.

Why It Has Not Disappeared

The speed of the shift has been real. The completeness of it has not.

Certain legal procedures still require the jitsu-in and its accompanying certificate — property transactions and inheritance proceedings among them. The underlying legal framework that the stamp system was built into does not change simply because administrative will has shifted; statutory revision moves at its own pace.

The cultural dimension is equally significant. For older generations, the hanko is not merely a tool — it is a familiar object associated with important moments, an understood form of commitment. Digital alternatives require trust in systems that feel less tangible, and that trust takes time to build across a population.

Within organizations, the stamp carries a function beyond legal compliance. A row of hanko impressions across an approval document is a visible record of who reviewed and authorized something. Replacing that with digital equivalents requires not just new software but a renegotiation of how organizational accountability is made legible. Some companies have managed this readily. Others are still working through it.

The hanko industry has responded by developing electronic seal products — digital reproductions of stamp impressions that can be applied to documents in online workflows. The concept of the hanko is being translated into digital form rather than simply abandoned, which suggests that even its critics recognize what it was doing that still needs to be done.

Hanko for Foreign Residents

For foreigners living in Japan, the hanko is a practical matter that arrives early.

Some banks still require a registered stamp to open an account, though this varies by institution and has been loosening. Rental contracts and various administrative procedures may request one. Foreigners typically have a stamp made with their name in katakana or roman letters — options are available at stationery shops, large pharmacies, and online, at prices ranging from a few hundred to several thousand yen depending on material and craftsmanship.

Having a basic hanko prepared when arriving in Japan is practical advice. The situations requiring one have become less common than they were, but they have not disappeared, and being without one at a necessary moment is an avoidable inconvenience.

Do You Need a Hanko in Japan Today? A Quick Guide

Since the administrative reforms that began in 2020, many procedures no longer require a stamp, but the situation depends on where you are and what you are doing. As a rough guide:

City hall procedures: most no longer require a hanko, though some forms still ask for one. Check with your ward or city office.
Banks: practice varies by bank. Many accept a signature from foreign residents, and online banks do not need one, but some branches still use a registered stamp.
Apartment contracts: a signature is generally accepted, though landlords and agents often use stamps. See our guide to renting in Japan.
Parcel deliveries and everyday paperwork: a signature is usually fine, and many deliveries need none at all.
Registered seals (jitsu-in): still required for some major legal procedures such as buying property.

Where to Buy a Hanko and What It Costs

Ready-made stamps for common Japanese surnames are sold at hundred-yen shops and stationery stores, and they are fine for everyday use. For a custom hanko, specialist stamp shops engrave one on request, often within the same day, and prices range from a few hundred yen for a basic plastic stamp to several thousand yen or more for wood or higher-quality materials.

Foreign residents can have a hanko made with their name in katakana or the Latin alphabet. If you want to register a seal (inkan toroku) at your local office, check what name format your residence record uses and what the office accepts.

Signature or Stamp? How Signing Works in Japan Now

In practice, most everyday situations accept a signature, such as credit card payments and hotel check-ins, and electronic signature services are now widely used for business contracts. Stamps remain common at some banks, in companies’ internal approval systems, and in a few legal procedures. If you are unsure, ask the organization what it accepts, and carry a hundred-yen mitome-in hanko just in case. For other contract-related customs, see the guarantor system.

What the Hanko Reveals

A small cylindrical object, pressed into red ink, leaving a circular mark on paper. The simplicity of the act conceals how much is embedded in it: centuries of administrative history, a particular theory of identity verification, an organizational culture built around visible authorization, and the friction that attends any attempt to change systems that have been load-bearing for a long time.

Japan is changing its relationship with the hanko — genuinely, measurably, in response to real pressure. But the pace of that change reflects something true about how deeply a tool can become part of a society’s structure when it has been there long enough. The hanko is not disappearing because Japan is resistant to change. It is lingering because replacing something that sits at the center of how trust and authorization work requires more than deciding to do it.
