Hanko — Japan's Personal Seal Stamps
Why Japan still runs on ink stamps instead of signatures — the vocabulary of hanko, and where the custom is (slowly) starting to change.
In Japan, official documents are traditionally authorized with 判子 (hanko) — a small carved stamp bearing your name, pressed in red ink — rather than a handwritten signature. Opening a bank account, signing a lease, or accepting a delivery has historically required your own registered hanko, not just your name written by hand.
Hanko basics
| Word | Reading | Meaning |
|---|---|---|
| 判子 | はんこ hanko | a personal name stamp/seal |
| 印鑑 | いんかん inkan | a more formal/legal term for the same kind of seal |
| 朱肉 | しゅにく shuniku | the red ink pad a hanko is pressed into |
| 実印 | じついん jitsuin | a hanko formally registered with the local government, used for major legal transactions |
Not all hanko are equal
There's a hierarchy of hanko formality. A cheap, mass-produced 三文判 (mitsumon-ban) is fine for signing for a package. A 銀行印 (ginkou-in) is registered specifically with your bank for account transactions. The most formal, 実印, must be registered with your local city office and is reserved for house purchases, cars, and other major contracts — losing or misusing it is treated seriously.
Levels of formality
| Word | Reading | Meaning |
|---|---|---|
| 三文判 | みつもんばん mitsumonban | a cheap, generic, unregistered stamp |
| 銀行印 | ぎんこういん ginkouin | a stamp registered specifically with a bank |
| 実印 | じついん jitsuin | the most formal, government-registered personal seal |
| 印鑑登録 | いんかんとうろく inkantouroku | the act of officially registering a seal with the city |
A tradition slowly giving way to digital signatures
The hanko system has drawn increasing criticism for slowing down paperwork and office culture — famously, an entire stack of internal documents might need a physical hanko stamp from every manager in a chain of approval (稟議, ringi). Since the pandemic pushed remote work, the government and many companies have been actively promoting digital signatures as an alternative, though hanko remain deeply embedded in daily bureaucratic life.
