How to Read Japanese Knife Maker's Marks and Kanji (Mei Guide)
Flip a Japanese knife over and you'll often find a row of kanji running down the blade or stamped near the heel. To a Western cook it looks like decoration. It isn't. Those characters are a compact record of who made the knife, where, and from what steel. Learn to read even a handful of them and a mystery blade turns into a knife with a name, a town, and a steel grade.
Flip a Japanese knife over and you'll often find a row of kanji running down the blade or stamped near the heel. To a Western cook it looks like decoration. It isn't. Those characters are a compact record of who made the knife, where, and from what steel. Learn to read even a handful of them and a mystery blade turns into a knife with a name, a town, and a steel grade.
This guide shows you how to decode those marks step by step. You don't need to read Japanese. You need a phone camera, a free lookup tool, and the pattern that almost every maker's mark follows.
Quick Answer
- Read top to bottom, right to left. A maker's mark (called a mei, 銘) usually runs vertically. The first characters often name the region or workshop; the last characters name the smith, frequently ending in 作 (saku, "made by").
- Three jobs, one stamp. Most marks tell you up to three things: the maker (brand or smith), the region (堺 Sakai, 関 Seki, 越前 Echizen), and the steel (青紙 Aogami / blue steel, 白紙 Shirogami / white steel).
- You can look up any character. Use Jisho.org's radical search or the SLJFAQ radical chart to draw or build a kanji you can't read, then match it against a smith index.
- Cross-check before you trust it. Confirm the smith and region against a maker's own site or the Nihonto Club swordsmith index — kanji alone can be faked, so the mark is a clue, not proof.
The rest of this guide breaks each of those points into a process you can run with a knife in one hand and a phone in the other.
What Is a Mei and Where Do You Find It?
Mei (銘) is the Japanese word for the signature or maker's mark cut, stamped, or etched into a blade. The tradition comes straight from sword making. On a katana, the smith chiseled his name into the nakago (茎), the unsharpened tang hidden inside the handle, and it was considered the smith's personal mark of authorship (Japanese Sword Index, kanji reference).
Kitchen knives inherited the habit. On a modern Japanese kitchen knife you'll usually find the mark in one of three places:
- On the blade face (left side as you hold it edge-down, tip right). Most kitchen knives put the maker's mark here because there's no hidden tang to sign.
- Near the heel or spine. Some makers stamp a short brand mark or steel grade close to the bolster.
- On the tang under the handle. Rare on kitchen knives, common on traditional single-bevel blades and anything sword-derived.
The mark can be applied three ways, and the method hints at price and tradition. Hand-chiseled marks (each stroke punched in by hand) signal traditional, often higher-end work. Stamped marks come from a die and are common on mid-range production knives. Laser-etched marks are the cheapest and most common on entry-level stainless blades. The marking method, in short, is one more clue about how the knife was made.
Knowing where to look matters because the mark's position and method are your first clue about how the knife was made — long before you read a single character. If you want the bigger picture of how kitchen blades descend from swords, see our companion piece on how Japanese knives evolved from samurai swords.
Which Way Do You Read the Characters?
Traditional Japanese text reads top to bottom in vertical columns, and the columns run right to left. A maker's mark follows the same rule, a convention carried straight over from sword signatures, which are read vertically from the top down (Japanese Sword Index).
So if you see a single vertical line of four characters, you read the top one first and work down. If there are two columns, start with the top of the rightmost column, read down, then move to the next column to the left.
Here's the pattern that holds for most marks, borrowed straight from sword signatures:
| Position in the mark | What it usually says | Example characters |
|---|---|---|
| First (top) | Region, province, or workshop | 堺 Sakai, 関 Seki, 越前 Echizen |
| Middle | Smith's name or brand | varies widely |
| Last (bottom) | A "made by" word | 作 saku, 製 sei, 謹製 kinsei |
On Japanese swords, the convention is that the opening characters give the province where the smith worked and the closing characters give the smith's name, often capped with a phrase meaning "made this" (Japanese Sword Index; Tokyo Nihonto, mei guide). Kitchen knives don't always follow it perfectly — many makers just stamp a brand name — but it's the best default pattern to start from.
One orientation note carried over from swords: the mei was traditionally cut so it faces outward, away from the wearer's body. For a kitchen knife you rarely need this, but if you're handling an old tang, hold the blade point-up with the edge to your left, and the signature should face you (Tokyo Nihonto).
What Does "Saku" Mean, and Why Is It on So Many Knives?
If you learn only one kanji, learn 作 (saku). It means "made" or "made by," and it's the single most useful anchor on a maker's mark.
Here's why. On a mark like 正本作 (Masamoto saku), 作 sits at the bottom and tells you the characters right before it are the maker's name (Japanese Sword Index). Find 作, and you've found the end of the signature — so the name is whatever comes just before it. It's a bookend that tells you where to look.
A few close relatives mean roughly the same thing and work the same way:
| Kanji | Reading | Meaning | What it tells you |
|---|---|---|---|
| 作 | saku | made (by) | Name comes just before it |
| 製 | sei | manufactured | Often follows a brand/company name |
| 製作 | seisaku | manufacture, craftsmanship | Same role as saku, two characters |
| 謹製 | kinsei | respectfully / carefully made | Polite "made by," upmarket tone |
| 鍛 | kitae / tan | forged | Signals a forged (not stamped) blade |
A three-character mark very often breaks down as two name characters + 作: for example, a smith's two-kanji name followed by 作 to say "[name] made this" (Japanese Sword Index). Once you internalize that, a huge share of marks suddenly have a readable shape, even if you can't yet pronounce the name.
Which Region Kanji Should You Recognize First?
Region characters are the easiest big win. There are only a handful of major knife towns, each with a short, recognizable kanji, and spotting one instantly narrows down the knife's origin and likely style.
Japan's main blade regions are Sakai, Seki, Echizen (Takefu), Tsubame-Sanjo, and Tosa (LeeKnives, knife-making regions of Japan). Here are the marks to memorize:
| Kanji | Reading | Region | Known for |
|---|---|---|---|
| 堺 | Sakai | Osaka area | Traditional single-bevel knives; Sakai-forged knives are used by the overwhelming majority of Japan's professional chefs (LeeKnives) |
| 関 | Seki | Gifu | High-volume production, stainless, big brands |
| 越前 | Echizen | Fukui (Takefu) | Forged blades, ~700-year tradition (Takefu Knife Village) |
| 土佐 | Tosa | Kochi | Rustic, hand-forged kurouchi blades |
| 三条 | Sanjo | Niigata | Tsubame-Sanjo metalworking cluster |
You'll also see region marks dressed up as a phrase. A stamp like 堺製 (Sakai-sei, "made in Sakai") pairs the region kanji 堺 with 製 (manufactured), telling you both the place and that it's a production claim rather than just decoration.
Why the region matters: each town has a house style. Sakai is famous for single-bevel traditional knives finished by specialist sharpeners; Echizen (centered on Takefu) is known for forged, full-tang blades and has held a continuous tradition for roughly 700 years (Takefu Knife Village). Read the region and you've already guessed a lot about the knife in your hand. For a deeper comparison, see Sakai vs. Seki vs. Echizen: Japan's three knife-making capitals compared.
How Do You Read the Steel Markings?
Some makers stamp the steel type right onto the blade, which is gold for a buyer. The "paper steels" from Hitachi's Yasugi works are the ones you'll meet most often, and their names come from the colored paper the mill used to wrap each grade for shipping (Kireaji, Yasuki steel).
| Kanji / mark | Reading | Steel | Notes |
|---|---|---|---|
| 白紙 | Shirogami | White Paper Steel | Pure carbon steel; very sharp, easy to sharpen, rusts |
| 青紙 | Aogami | Blue Paper Steel | White steel + chromium & tungsten; tougher, better edge holding (Jikko) |
| 鋼 | hagane | (carbon) steel | Generic "this is hard carbon steel" |
| 黄紙 | Kigami | Yellow Paper Steel | Entry-level carbon steel |
| ステンレス | suterenresu | stainless | Katakana for "stainless" |
| 安来鋼 | Yasukikou | Yasugi steel | Steel made at Hitachi's Yasugi works (Kireaji, Yasuki steel) |
Those paper steels trace back to one source. The white and blue steels are produced by Yasugi Specialty Steel (YSS), made at the Yasugi works in the San'in region of Japan, a place known for the high purity of its iron sand and a steelmaking lineage that runs back to the traditional tatara ironmaking craft (Proterial / Hitachi Metals, YSS). White steel is the closest modern descendant of tamahagane (玉鋼), the iron-sand steel used for swords.
A note on the two big carbon families, because it's the question every buyer asks. Shirogami (white) is the purer steel — fewer alloying elements, which makes it take a screaming edge and sharpen easily, at the cost of toughness and rust resistance. Aogami (blue) is white steel with chromium and tungsten added, which boosts toughness and edge retention (Jikko Cutlery). If your blade is stamped 青紙 or 白紙, you already know a lot about how it'll behave. We go deep on this in Shirogami (white steel) vs Aogami (blue steel): full breakdown and Hitachi Yasuki steel grades explained.
Not every steel gets a kanji. Modern alloys are usually written in Latin letters or katakana — VG10, SG2, R2, ZDP-189 — so if you see "VG10" laser-etched on a blade, that's the steel grade, plain and simple.
How Do You Look Up a Kanji You Can't Read?
This is where most people freeze, but it's the easy part. You never have to "know" a kanji to identify it. You can look up any character by its shape. Here's the workflow.
Step 1 — Photograph the mark cleanly. Use side lighting, not direct flash. Angle the blade so the engraving throws a small shadow and the strokes pop. Get the characters sharp and square in frame. Count how many characters there are — that number alone helps you guess the structure.
Step 2 — Pick a lookup method. You have three good options:
| Method | Tool | Best for |
|---|---|---|
| Draw it | Jisho.org handwriting input | You can roughly copy the strokes |
| Build it from radicals | Jisho radical search / SLJFAQ radical chart | You recognize component parts |
| Photo translate | Google Translate or Google Lens camera | Fast first pass, can misread |
Step 3 — Use radical search the smart way. A radical is a building-block component shared across many kanji. On a radical-search tool you tap the parts you can see, and as you select them, every radical that never appears with your choices grays out — which quickly narrows thousands of characters down to a short list (Jisho radical search behavior; Tofugu, how to look up kanji). Counting strokes speeds it up further.
Step 4 — Match the readings to a name. Once Jisho gives you the character and its readings, you can string the name together. Watch out: many kanji have multiple readings, so a name might be pronounced several ways. That's normal — note the characters themselves, not just one guess at pronunciation.
Step 5 — Cross-reference the smith. Take the name characters and check them against the maker's own website or a smith index like the Nihonto Club swordsmith index, which catalogs makers with their signatures and provinces. (Nihonto Club also runs a dedicated mei/signature search tool, though free membership may be required to use it.) For kitchen knives, a maker's official site is usually the fastest confirmation.
Photo translation apps are tempting, and they're a fine first pass, but they misread hand-chiseled or stylized marks constantly. Treat the app's guess as a hint and confirm it with radical search plus a smith index. If you'd rather get a human read, the kitchen-knife forums are full of people who enjoy translating marks from a clear photo.
What Can the Mark Tell You — and What Can It Not?
A maker's mark is a powerful clue. It is not a certificate. Keep these limits in mind so you don't over-read it.
What the mark reliably tells you:
- The intended brand or smith name.
- The claimed region of origin.
- The steel type, when stamped.
- The construction hint — 鍛 (forged), 本焼 honyaki (through-hardened), and similar terms describe how it was made.
What the mark can't prove on its own:
- Authenticity. A famous name can be copied. Counterfeit and "tribute" blades stamp respected names onto lesser knives. Treat the mark as one data point among many — feel, fit, finish, and seller reputation matter more.
- Who actually ground it. In Sakai especially, forging, sharpening, and handle-fitting are done by different specialists. The name on the blade is often the forging workshop or the brand, not a single "maker" who did everything (LeeKnives).
- Exact age or value. Kitchen knife marks rarely carry reliable date inscriptions the way old swords do.
So read the mark, then sanity-check it. Does the steel stamp match how the blade behaves? Does the region match the knife's style? Does the seller's story line up with the characters? When the mark, the knife, and the source all agree, you can trust your read. When they don't, the mark is the thing to doubt. For a full process, see how to spot a fake Japanese knife.
A Worked Example: Reading a Mark From Scratch
Say you've got a knife with four characters running down the blade and you can't read any of them. Here's the whole process in order.
- Frame and light it. Side light, sharp photo, count the characters. Four characters, single column.
- Read top to bottom. Character 1 is the start, character 4 is the end.
- Look for an anchor. Is the bottom character 作 (saku) or 製 (sei)? If yes, characters above it are the name. If the top is a region kanji like 堺 or 関, you've got origin + name + "made by."
- Look up the unknowns. Drop each unknown character into Jisho's radical search or draw it with handwriting input. Build the readings.
- Assemble the meaning. Region (if present) + smith/brand name + saku.
- Confirm. Search the name plus "knife" or "hamono," check the maker's site, and cross-reference the Nihonto Club index if it's a traditional smith.
Run that loop a few times and it gets fast. The anchor characters (作 / 製) and the region kanji (堺 / 関 / 越前) do most of the heavy lifting, and everything else is just lookup.
Common Kanji Cheat Sheet
Keep this handy. These are the characters you'll meet most often on Japanese kitchen knives, grouped by job.
| Kanji | Reading | Meaning | Job on the mark |
|---|---|---|---|
| 作 | saku | made (by) | Name bookend |
| 製 | sei | manufactured | Brand/company bookend |
| 鋼 | hagane | steel (carbon) | Steel type |
| 白紙 | shirogami | white paper steel | Steel type |
| 青紙 | aogami | blue paper steel | Steel type |
| 鍛 | kitae | forged | Construction |
| 本焼 | honyaki | through-hardened | Construction |
| 堺 | Sakai | Sakai region | Origin |
| 関 | Seki | Seki region | Origin |
| 越前 | Echizen | Echizen region | Origin |
| 土佐 | Tosa | Tosa region | Origin |
| 包丁 | hocho | kitchen knife | Object name |
| 名 / 銘 | mei | name / signature | The mark itself |
If you commit just the bold-job characters to memory — 作, 製, plus the three big region kanji and the two paper-steel pairs — you'll be able to make sense of the majority of kitchen-knife marks you encounter.

Frequently Asked Questions
Do I read a maker's mark left to right or top to bottom? Top to bottom, and when there's more than one column, right to left. Japanese text runs in vertical columns read from the top, with the columns moving right to left — the same way sword signatures are read (Japanese Sword Index). Start at the top of the rightmost column.
What does the character 作 mean on a knife? It's read saku and means "made" or "made by." It's the most useful character to learn because it usually sits at the end of the signature, telling you the characters just before it are the maker's name (Japanese Sword Index).
How can I identify a kanji I can't read at all? Look it up by shape. Use Jisho.org's handwriting input to draw it, or use radical search where you tap the component parts and the tool narrows the matches (Tofugu). You never need to know a character in advance to identify it.
Does the mark prove my knife is authentic? No. A famous name can be copied, and counterfeit blades stamp respected names onto cheaper knives. Use the mark as one clue, then check the knife's feel, finish, steel behavior, and seller against the name before trusting it. (See our guide to spotting a fake Japanese knife.)
Where do "white steel" and "blue steel" names come from? From the colored paper the mill wrapped each grade in for shipping (Kireaji, Yasuki steel). The steels are made by Hitachi's Yasugi Specialty Steel works, which draws on Japan's high-purity iron sand and the old tatara ironmaking tradition (Proterial / Hitachi Metals).
