Marks

There are characters on your pot — on the base, on the painted face, or cut into the body — and no obvious way to find out whose they are. This index covers thirty makers and kilns, with documented mark forms and series listed below. Every maker here also has a page of their own, which is the test for going in.

First · この索引の使い方

How to look
something up

Start with what you can see without reading anything. Count the characters — the index is grouped by that — and then look at how the mark was put on. A mark pressed into the clay, a mark cut into it with a point, and a mark painted on are three different things, and telling them apart removes most of the list at once.

If you can already type the characters, or you know the name and want the mark, use the search box. It matches the characters, the romanised name and the region together.

This index identifies marks. It does not authenticate pots. A seal can be copied, inherited, or used by a workshop rather than a person, and several of the entries below say so. Where a mark cannot settle a question, we have said which question it cannot settle.

The characters on your pot may not look like the characters below. Many stamped seals use 篆書体, an archaic script commonly used for seals: a mark reading 美芸 is carved in shapes an ordinary reader of Japanese would struggle with. Brushed and scratched signatures may use other scripts. What is given here is the reading — the characters in modern type. Use it to confirm a transcription, to narrow by length and manner, and for the cautions.

Photographs are scarce here on purpose. The only marks shown are ones documented on individual pots, so this part of the index grows one pot at a time.

The left-hand column is the reading of the mark, displayed vertically here as a reading aid; this is not a reconstruction of the mark’s layout, and it is not a picture of the seal. Where the arrangement is recorded it is given underneath. A name in gold has a page of its own.

What the manner words mean
Stamped 押印 — a seal pressed into the clay before firing
Scratched 釘書 — cut into the clay with a point, usually at the foot
Brushed 書銘 — written on, in pigment or glaze
Mixed the same maker uses two or more of these
In relief raised rather than pressed in
Cast 鋳銘 — cast into the metal, on bronze trays
Technique not established how the mark is made is not confirmed
Unmarked no mark is documented, or the work is recorded as unsigned

One character

一字 2

The hardest to attribute and the easiest to misread, because a single character carries no context. Several makers here share one.

武incised; used on bonsai pots火incised; used on bonsai potsalso 樋口武, 梅香

Hyogo·Scratched

Higuchi Takeshi

樋口武

Several incised marks are currently documented for him. Other forms may exist. 樋口武, 武 and 火 are documented on bonsai pots; 梅香 is documented for ceramics other than bonsai pots. On bonsai pots, the incised inscription could also include the date of making.

矩carved or stamped at the foot — confirmed on an observed potalso 是好

Mixed

Zeko

是好

Two systems, both genuine, in two places. 是好 is a brushed signature in enamel on the painted side, the two characters run together. 矩 is the other mark, carved or stamped at the foot. 是好 appears on the painted face; 矩 has been confirmed on the base of an observed pot. Both are genuine.

Two characters

二字 19

The largest group in this index; many art names here are two characters.

一陽(角印)square stamp; pre-war, the earliest of the documented forms一陽(楕円印)oval stamp; used from 1933一陽(丸印)round stamp; cut on the same original seal as the ovalalso 三琇園一陽

Mikawa·Stamped

Sanshu Ichiyo

三琇一陽

Four mark forms are currently documented for him. Other forms may exist. The square 一陽 is the earliest of the documented forms, pre-war. The oval 一陽 was used from 1933, based on a seal he was given. The round 一陽 was cut on the same original seal as the oval stamp, one at each end. The square 三琇園一陽 was also used after the war. These dates describe when a mark form was in use, not when a particular pot was made.

仙舟no square frame — the outline follows the characters
The two-character mark 仙舟 on the base of a Senshū pot. No square frame — the outline follows the characters themselves. It sits in the middle of the base, a little below centre, among the drainage holes, on the bare body.

Tokoname·Technique not established

Senshu

仙舟

Two characters in a loosened seal-script style, joined into an irregular outline without a square frame. This mark matters more than most: Senshū inherited Shūzan's clay recipe, forming and firing, so body and form alone may not reliably distinguish the two.

光峰the moulded line of Ichinokura Sekishū, Mino — not 鴻陽 of Tokoname
A mark on an unglazed pot, recorded as 光峰: two characters on the body, photographed in raking light. How the mark was made is not confirmed. 光峰 is Kōhō, of Mino; 鴻陽 of Tokoname is Kōyō — a different reading and a different maker.

Mino·Technique not established

Koho

光峰窯

The mould-made line from about 1970, made at the workshop — not Ichinokura Sekishū's own hand-built pots. A boxed set can carry both 光峰 and 石州.

光峰the moulded line, from about 1970 — a line, not a personalso 市之倉石州造, 市之倉石州, 石州造The first is cut into a tall white panel

Mino·Mixed

Sekishu

市之倉石州

光峰 is the mould-made line, from about 1970; 市之倉石州 is the hand-made work, from about 1972. Two names, one potter, two lines.

是好brushed in enamel on the painted face, not the footalso 矩

Mixed

Zeko

是好

Two systems, both genuine, in two places. 是好 is a brushed signature in enamel on the painted side, the two characters run together. 矩 is the other mark, carved or stamped at the foot. 是好 appears on the painted face; 矩 has been confirmed on the base of an observed pot. Both are genuine.

服部scratched — two impressions, differing in script

Tokoname·Scratched

Hattori

服部

Two impressions are documented, differing in script. Both are his.

柴勝two documented stamped forms

Tokoname·Stamped

Shibakatsu

柴勝

Two documented stamped forms both read 柴勝. Other forms may exist. One is documented in connection with the handmade work of his newer direction; the other with the earlier press-moulded production ware. Telling them apart requires a direct view of the mark; a listing photograph may not be enough.

桂雲Keiun — written by hand, not stamped
An observed pot bears 桂雲 cut freehand into the foot, the two characters arranged vertically with no frame. The reading comes from this single example and has not yet been confirmed from another pot.

Scratched

Keiun

桂雲

Cut into the foot freehand with a point, in a running hand, with no frame — not a stamp. This is the only mark form currently documented for him, and it rests on a single observed example.

梅香incised; used on ceramics other than bonsai potsalso 樋口武, 武, 火

Hyogo·Scratched

Higuchi Takeshi

樋口武

Several incised marks are currently documented for him. Other forms may exist. 樋口武, 武 and 火 are documented on bonsai pots; 梅香 is documented for ceramics other than bonsai pots. On bonsai pots, the incised inscription could also include the date of making.

樹晃an upright seal — his art name, read ju-kō

Tokoname·Stamped

Juko

樹晃

樹晃 is confirmed. 晃 and 樹晃造 appeared in earlier unsourced text and remain unverified.

正志Masashi — a square seal, his own name

Stamped

Furumoto Masashi

古本正志

Two forms are currently known for him, and both read 正志: a square seal, and a gourd-shaped impression on the pot shown here. How the two relate is not settled.

祥石Shōseki — one documented brushed form
A brushed 祥石 signature in cobalt beneath the glaze, on the foot of a pot shown here, the two characters one above the other. A brushed signature is the technique recorded for her; the impressions themselves have not been compared. Whether other forms exist is not established.

Brushed

Ishida Shoseki

石田祥石

Shōseki is more than one maker. 石田祥石 of Ibaraki is documented, and separately Matsumoto Shōseki, written 松石. The ゆうき祥石 kiln is neither of them. No relationship between the three is established.

美芸stamped into the foot before firing

Tokoname·Stamped

Bigei

美芸

A single stamp of the art name, pressed into the foot before firing.

平田涼美, born 1939. He entered the trade in 1958, began making pot bodies in 1969, and opened his own kiln in 1975.

耀山pressed in — three stamp forms are documented; the pot shown here carries the oval form
The pot shown here bears an oval stamp on the foot, with two characters arranged vertically; the lower is 山. Compared directly with the 英明 seal, the characters are clearly different. This is 耀山’s mark, not 英明’s.

Tokoname·Stamped

Yozan

耀山

The character is 耀, with the light radical — not 燿.

舟山(楓款)set in a maple leaf — often small pots舟山(極小楓款)about 1 cm tall — small pots, probably earliest舟山plain — medium pots, probably earlyalso 舟山 + 総手造証, 鼎形の印

Stamped

Shuzan

舟山

Five forms are recorded. The tiny maple-shaped one — about 1cm tall, on small pots — resembles Heian Tofukuji's maple mark and is easy to miss altogether in a listing photograph. The bronze-vessel shape is the one that stands for Shūzan's work, on medium and large pots.

英明an oval stamp — two characters, one above the other
The pot shown here bears an oval seal on the foot, photographed in raking light. Two characters are arranged vertically. Above it is a separate inscription cut with a point; its exact characters remain unconfirmed.

行山written — small pots翁山Ōzan — only the five Ōkuma copies, 1984also 行山造印, 中野行山造

Tokoname·Mixed

Gyozan Nakano

中野行山

The mark tells you how the pot was made. Stamped 行山造印 goes on pots made from a mould in some quantity; scratched 中野行山造 on slab- and coil-built pots made singly or in small numbers; 行山 on small pots. Commemorative pots carry a scratched inscription naming the exhibition. 翁山 is different again: he used it on nothing but the five copies of the Ōkuma Shigenobu pot, made in 1984. One caution goes with all of this — in Tokoname, press-moulding is usually counted as handwork. Gyōzan does not count it that way, so this reading of his marks does not transfer to other makers.

雄子amateur-period form雄山(横長)long, horizontal; early period雄山(一重枠)single-frame series; used from 1973 to 1977雄山(二重枠)double-frame series; used from 1978雄山(1993年以降・枠あり)later framed form; used from 1993雄山(1993年以降・枠なし)later unframed form; used from 1993also 藤掛雄山, 雄山造

Gunma·Stamped

Yuzan Fujikake

藤掛雄山

Several mark forms and dated series are currently documented for him. Other forms may exist. 雄子 is from his amateur years; a long, horizontal 雄山 is early; 藤掛雄山 in four characters was used for special orders. A single-frame series was used from 1973 to 1977 and a double-frame series from 1978. 雄山造 and later framed and unframed forms of 雄山 were used from 1993. These periods describe when a form or series was in use, not when a particular pot was made.

鴻陽(扇形)fan-shaped seal — documented in connection with small pots鴻陽square stamp — a second form of the same namealso 鴻陽造, 鴻陽陶園, 山型の款

Tokoname·Stamped

Koyo

鴻陽

A fan-shaped 鴻陽 seal is documented in connection with small pots. The mountain-shaped mark is not a maker's mark; it means 芙蓉園撰, selected by 芙蓉園.

Three characters

三字 8

Usually a two-character name with 造 or 作 after it: made by.

山房造production ware, retiredalso 山房鳳舟, 山房造風亭, 山房造印

Tokoname·Stamped

Yamafusa

山房

The mark tells you the line and roughly the date. 山房造 is the volume ware; 山房鳳舟 and 山房造風亭 are the better work. By 2006, 山房造印 had come to cover all grades.

松泉焼Shōsen — handmade, 1995 onwards山秋造stamped — made in some quantityalso 松泉焼山秋造, 小松泉作, 小松泉造, 金華造印

Tokoname·Mixed

Yamaaki

山秋製陶所

A datable set. 小松泉作 and 小松泉造 are hand-made pots from before 1995; 松泉焼 and 松泉焼山秋造 are hand-made after the succession. A stamped 山秋造 means a pot made in some quantity, and 金華造印 is the previous generation, pre-war.

楓落款inside a maple-leaf outline — a similar maple seal is documented for 舟山東福寺(円枠)round frame, blocky face東福寺(釘書)scratched into the raw clay, not stamped東福寺(明朝体)serifed, printed-type characteralso 平安東福寺

Kyoto·Mixed

Heian Tofukuji

初代平安東福寺

Seven forms are recorded, and he used more than one on a single pot often enough that double marks are a recognised category of their own — the commonest pairing being the square seal-script 平安東福寺 with an oval running-script 東福寺.

樋口武incised; used on bonsai potsalso 武, 火, 梅香

Hyogo·Scratched

Higuchi Takeshi

樋口武

Several incised marks are currently documented for him. Other forms may exist. 樋口武, 武 and 火 are documented on bonsai pots; 梅香 is documented for ceramics other than bonsai pots. On bonsai pots, the incised inscription could also include the date of making.

石州造brushed straight onto the bodyalso 市之倉石州造, 市之倉石州, 光峰The first is cut into a tall white panel

Mino·Mixed

Sekishu

市之倉石州

光峰 is the mould-made line, from about 1970; 市之倉石州 is the hand-made work, from about 1972. Two names, one potter, two lines.

鴻陽

A fan-shaped 鴻陽 seal is documented in connection with small pots. The mountain-shaped mark is not a maker's mark; it means 芙蓉園撰, selected by 芙蓉園.

黎鳳造intaglio, a tall upright seal — the documented markalso 黎鳳造印Tall stamp, cut in
The pot shown here bears a raised mark in a rounded rectangular frame. It differs from the upright intaglio 黎鳳造. Another mark, 黎鳳造印, is also documented, but no confirmed impression is available for comparison, so the two cannot yet be matched.

Tokoname·Stamped

Reiho

黎鳳

黎鳳造 is cut in intaglio as a tall upright seal. A second mark, 黎鳳造印, is documented as having come into use by 2006. He worked in two lines — glazed pots after the old Chinese colours, and the unglazed nanban stoneware he began around 1996 — but no exclusive association between either mark and either line has been confirmed. Not to be confused with 礼峰 of the Matsushita pottery, also read Reihō.

Four characters

四字 12

Often a place or a kiln in front of the name.

一弘造印Ikkō-zō-in — his own work壱興造記Ikkō-zō-ki — pots made with bonsai nurseries壹興造記the same again, with the formal 壹

Tokoname·Stamped

Three marks are recorded, and the second and third read the same as the first — ikkō. 壱興 and 壹興 are the marks used on the small pots made in partnership with bonsai nurseries. One man, three spellings. A 一弘造 stamp and a scratched version are also documented.

Recorded examples include 秀峰造 written with a point above a square 義村陶園 stamp. Other recorded stamps include 義村造印, 義村陶園 and 義村秀峰之印. Other forms may exist. 秀峰 was taken as a name in 1974; that date describes the succession, not when the mark began to be used.

藤掛雄山four characters; used for special ordersalso 雄子, 雄山(横長), 雄山(一重枠), 雄山(二重枠), 雄山造, 雄山(1993年以降・枠あり), 雄山(1993年以降・枠なし)

The mark tells you how the pot was made. Stamped 行山造印 goes on pots made from a mould in some quantity; scratched 中野行山造 on slab- and coil-built pots made singly or in small numbers; 行山 on small pots. Commemorative pots carry a scratched inscription naming the exhibition. 翁山 is different again: he used it on nothing but the five copies of the Ōkuma Shigenobu pot, made in 1984.

金華造印Kinka-zō-in — pre-war, the first generation’s

Tokoname·Stamped

Juodo Shosen

十王堂松泉

No mark of the first generation's own is documented. The two given as representative are the present holder's, and the pre-war 金華造印 is named without an impression.

銭子窯製seal script — copied from an imported Chinese pot before the war

Tokoname·Stamped

Zengo

銭号

This mark is not evidence of a Chinese pot. It began as the mark of an imported Chinese pot and was copied along with everything else when Tokoname made Chinese-style pots before the war. The trade name Zengō comes from the seal-script 子 looking like 号.

舟山

Five forms are recorded. The tiny maple-shaped one — about 1cm tall, on small pots — resembles Heian Tofukuji's maple mark and is easy to miss altogether in a listing photograph. The bronze-vessel shape is the one that stands for Shūzan's work, on medium and large pots.

Five or more

五字以上 10

In this index, long marks usually name a kiln, a workshop or a commission rather than a person alone.

Mikawa·Stamped

Sanshu Ichiyo

三琇一陽

Four mark forms are currently documented for him. Other forms may exist. The square 一陽 is the earliest of the documented forms, pre-war. The oval 一陽 was used from 1933, based on a seal he was given. The round 一陽 was cut on the same original seal as the oval stamp, one at each end. The square 三琇園一陽 was also used after the war.

Heian Tofukuji II

二代平安東福寺

He kept the first Tofukuji's marks and added 二代 — or 勇 — among other additions. An addition such as 二代 or 勇 can identify the second Tofukuji; its absence does not identify the generation because the earlier marks were inherited.

松泉焼山秋造Shōsen — handmade, 1995 onwardsalso 松泉焼, 小松泉作, 小松泉造, 山秋造, 金華造印

Questions

Common questions

How do I look up the mark on my bonsai pot?

Start with what you can see without reading anything. Count the characters, since the index is grouped by that, then look at how the mark was put on: pressed into the clay, cut with a point, or painted.

Does a mark prove a bonsai pot is genuine?

No. The index identifies marks; it does not authenticate pots. A seal can be copied, inherited, or used by a workshop rather than a person.

Why does the mark on my pot not look like the characters in the index?

Many stamped seals use 篆書体, an archaic script commonly used for seals, so the shapes can be hard for an ordinary reader of Japanese to read. The index gives the reading in modern type.

Documented, not guessed

Every entry here states what is documented and nothing more. Where a question is unsettled we say so rather than pick a side; where a reading is not confirmed we say that, instead of printing a guess. Where an entry is based on a single observed example rather than a confirmed general pattern, we say so.
