What this tool does
HANEHanko is a free tool that turns a name or company name into an image that looks like a Japanese hanko (also called an inkan) — the personal or company seal stamped in red ink that Japan uses instead of signatures on many documents. No installation or sign-up is needed. Everything is drawn inside your browser — the name you type is never sent to or stored on a server.
-
⭕4 seal styles
Make a round personal seal, a double-circle company seal, a square company seal (kakuin) or a date stamp. The layout adjusts automatically to the number of characters.
-
🎨Typeface, color and weight
Choose a typeface such as Mincho or Gothic, a color such as vermilion, red, indigo or black, and the weight of the border and text.
-
🖼Transparent PNG
The image has a transparent background, so it won't hide the text underneath when you place it on Word, Excel or PDF documents.
-
🩸Worn ink effect
Add the blur and gaps of real ink-pad ink, and tilt the seal slightly, for a look closer to a hand-pressed stamp.
-

When it comes in handy
Stamping internal forms and circulars
Paste a personal seal image instead of printing, stamping and scanning the document again.
Many Japanese workplaces still ask for a hanko on internal forms and approval sheets. For documents that don't need legal force, a seal image is often enough — no more printing, stamping and scanning, so approvals go faster.
For documents going outside your company or anything related to contracts, always check the recipient's rules.
Adding a company seal to quotes and invoices
Choose “Square” and enter your company name to make the square company seal commonly seen on Japanese invoices.
A square seal usually reads the company name followed by 之印 (“seal of”). The tool arranges the characters in columns automatically based on their number. Paste the image into Excel or Word and place it behind the text so it overlaps the company name naturally.
Recording a received or checked date
The date stamp combines a department, a date and a name in one round seal.
This style is used in Japan to record the day a document was received or checked. You can change the date freely, including in the Japanese era format (e.g. R8 = Reiwa 8 = 2026).
A seal image made with this service is not guaranteed to be accepted as an official seal for every contract or procedure. It cannot replace a registered seal such as a jitsuin (registered personal seal) or ginkōin (bank seal). Always check the rules of the organization or business partner you are submitting to. Creating or using a seal in another person's or company's name without permission may be against the law. Typefaces are loaded as web fonts, so the seal looks the same even if the fonts are not installed on your computer; loading may take a moment on a slow connection.
