Hanko Etiquette and Practical Use

How to use a hanko in Japan comes down to two layers: the physical skill of producing a clean impression, and the document conventions that surround it. Orientation, red ink control, and even pressure handle the first layer; placement, page stitching, and correction rules handle the second.12

Confirm current details with official sources

Procedures, fees, and requirements can change. Confirm current details at the bank, notary, or municipal office receiving your document, since institutional rules add to the general practice below.

Overview​

A clean impression is read as competence at banks and notary offices, while a smudged or tilted one invites questions and sometimes a fresh form.2 The rest of this article builds the skill step by step, then covers the conventions for placement, multi-page documents, corrections, and custody.

The tools: seal, ink, and mat​

Use the red ink pad, the 朱肉 (shuniku, "red ink pad for seals"), not a standard blue or black office pad. Red is the expected color for formal and legal documents, while other colors belong to casual or workplace contexts at most.234

Load the seal with a single light vertical press onto the pad: gentle, even, about one second, no rocking or dragging.2 Too much ink bleeds the character lines together; too little leaves gaps. A thin even film across the whole seal face is the target.

A stamping mat, the 捺印マット (natsuin matto, "stamping mat"), placed under the paper evens out pressure and stops slipping on uneven desks.1 Pads dry from the edges inward, so a faint impression calls for refill ink rather than harder pressing.2

Stamping technique step by step​

Find the top notch first. Most hanko carry a small notch or mark on one side indicating the top, so the characters read correctly in the impression.24 Check it before inking, not after.

Then follow the sequence: position the seal face over the target area before descending, grip between thumb and fingers without tensing, stabilize the paper with the other hand, press straight down through the center, hold about two seconds, and lift straight up without peeling to one side.12

Hanko ink is oil-based and needs a moment to transfer, so lifting fast smears or breaks the impression.2 Test every session on scrap paper first, and re-ink between impressions rather than stretching one inking across several stamps.2

Practice the full sequence on scrap paper first

Official forms often use coated or heavier stock that behaves differently from plain scrap. One test stamp on similar paper reveals ink load and pressure problems while they are still free to fix.2

Placement rules​

Stamp inside the designated seal box where the form provides one. Without a box, place the impression immediately after or beside the handwritten name, close enough to read as confirming that name.54

Keep the impression clear of text and other seals so verifiers can read it cleanly.5 Stamp once unless asked for multiple copies, and disclose a smudged impression rather than silently stamping over it.24

Multi-page documents: stitching seals​

Multi-page documents that must read as one consistent set use stitching seals across the binding edge or between pages. The 割印 (wari-in, "stitch seal across joined pages or copies") spans two counterparts of the same contract held by each party, while the 契印 (kei-in, "seal across a document binding edge") spans the seam of bound pages.5

Revenue stamps get their own treatment. The 消印 (keshi-in, "revenue-stamp cancellation seal") is struck across the stamp and the paper to prevent reuse, and need not be the same seal used for signing.5 A document found without its cancellation can draw a penalty tax equal to the stamp's value, though the document itself stays valid.5

Correcting mistakes​

The standard correction runs: draw two lines through the error, write the correction alongside in the prescribed position, then stamp the 訂正印 (teisei-in, "correction seal") at the correction or in the margin with all parties' seals, noting the characters removed and added.5

The 捨印 (sute-in, "pre-stamped blank correction seal") is a margin seal placed in advance to permit later corrections. Because it pre-authorizes alterations to the document, it should be used as little as possible.5

On official documents a failed impression generally cannot be fixed by re-stamping. Double impressions read as tampering on formal paperwork, so ask whether a fresh form is available instead.2

Ask the receiving counter about corrections first

Correction conventions vary by institution, and some counters accept only their own prescribed method. A quick question before touching the document beats a rejected filing after.5

Storage and custody etiquette​

Store seals in a case in a fixed secure place, with the registered seal apart from everyday seals. Do not carry the jitsuin daily; it stays home until a procedure calls for it.6

Only the owner uses the seal. Letting someone else stamp, even with permission, is treated as an identity problem in serious contexts.16 Worn, faint, or damaged impressions cause delays or refusals, so inspect the carving and replace deteriorating seals before they fail at a counter.6

Stamping a contract is treated as a formal moment after reviewing every clause, with the seriousness of signing a legal agreement elsewhere. Read first, stamp once, and treat the act as the commitment it is.6

Good to know​

Practice on scrap paper before the formal stamp​

Ink load, hand tension, and paper surface all change the result, and nerves make hands faster and tenser exactly when it counts. Slowing down deliberately on a test sheet removes most first-try failures.2

A bad impression usually needs a fresh form, not a re-stamp​

Prevention beats correction on formal paperwork. If the impression smears, doubles, or tilts badly, ask the issuing counter for a fresh copy rather than layering a second stamp over the first.2

Never lend your registered seal​

The impression is the identity reference, so anyone holding the registered seal can attempt acts in your name. The everyday seal is already the shareable-risk object; the registered one never leaves your custody.6
