Japanese rebus monogram

A Japanese rebus monogram is a monogram in a particular style, which spells a name via a rebus, as a form of Japanese wordplay or visual pun. Today they are most often seen in corporate logos or product logos.

A bottle of Yamato Shizuku (やまと しずく, Japan droplet) sake (name spelt out at top right), with a rebus ∧ト💧 which is read as yama (, mountain) (symbolized by the ∧) + to (, katakana character for to) + shizuku (, droplet) (symbolized by the 💧).

These symbols are particularly common for traditional food brands, notably soy sauce.[1] An example is the logo for Yamasa soy sauce, which is a ∧ with a サ under it. This is read as Yama, for yama (, mountain) (symbolized by the ∧) + sa (, katakana character for sa).


The monogram is composed of two parts: one a Japanese character, most often kanji, but also katakana or hiragana;[a] the other a simple symbol, such as a circle or square. The symbol is pronounced according to its name, and together (in either order, but generally symbol first) these form a Japanese name.

Japanese family names are generally two kanji characters, each usually of one or two morae – hence one or two hiragana or katakana if written that way – and thus can be represented as one symbol plus one kanji character, sometimes one hiragana or katakana. Only a few symbols are used, and thus only a few names can be written as a monogram this way. A name may be represented by a symbol that does not correspond to it but is homophonous – further punning – which is aided by the large degree of homophony in Japanese. For example, kane (, metal) in a name may be represented by the symbol ┐, though this actually corresponds to kane (, carpenter's square); or -en (, ... garden) in a name may be represented by the symbol ○, though this actually corresponds to en (, circle).


There are many variations on this basic design – only one character from the name may be used, the pronunciation need not correspond to an actual name, other typographical symbols can be used (like shime),[2] two symbols (and no characters) may be used[2] – for example, Maruyama (円山) can be spelt as ○∧ – and unpronounceable or unpronounced symbols may also be incorporated decoratively.

For example, the Yamasa symbol was created as a modification of the boat emblem of the Kishū branch of the Tokugawa clan, which was composed as ∧ + キ, with キ for ki in Kishū and the ∧ purely decorative. The Yamasa variant turned the キ on its side and reinterpreted it as a サ sa; the resulting Yamasa reading does not correspond to an actual name (the family name is instead Hamaguchi), though it sounds like a family name and such a family name does exist (e.g., in form 山佐).

These readings are used for other symbols as well. Most commonly, a circled symbol is pronounced maru + (symbol reading), for "circle" (, maru); circling a symbol is common, dating to circular seals. A notable example is the tax inspection division (査察部, sasatsubu) of the National Tax Agency, which uses a circled sa () as their symbol. They are thus known colloquially as the Marusa, from 〇査 (maru + sa). This is notably present in the movie title A Taxing Woman (マルサの女, Marusa no onna). As katakana this would be written as ㋚; see Enclosed CJK Letters and Months for standard circled symbols.

A bottle of Kikkoman soy sauce

Rarer variants exist, like Kikkou man (亀甲萬, tortoise-shell 10,000) for Kikkoman soy sauce (tortoises are said to live for 10,000 years), which uses a hexagon to symbolize a tortoise shell (亀甲), with man (, 10,000) inside.

Common symbolsEdit

Only a handful of symbols are commonly used, though some have different readings; these are:[2][3]

Symbol Reading Kanji Description Other character's position
maru circle inside the circle
en circle
yama mountain under the mountain
kane carpenter's square inside the angle
kado corner
kaku box inside the box
hishi, bishi diamond, rhombus inside the box


There is no standard everyday Japanese term for these monograms. Rather, they are referred to by their use, such as "trade name" (商号, shōgō),[2] "store name" (屋号, yagō),[3] etc., or generically as "symbol" (標号, hyōgō), "symbol mark" (シンボルマーク, shimboru māku),[2] etc.


As designs and corporate symbols, these date at least to the mid-17th century, and early on were featured on noren, as the example of Yamasa indicates. They presumably come from the graphic tradition of the battlefield flags of the Warring States Period (Sengoku period, mid-15th to early 17th century), as seen in the simple clan name designs of Sashimono and Uma-jirushi. More broadly, these come from the same heraldic tradition as mon, where family emblems are pronounced according to the design, yielding the family name, as in Mitsu-ya ("three arrows"). Note that while many mon feature a kanji from the family name, the mon as a whole is not pronounceable as the full name.

During the Edo period, pictorial rebuses known as hanjimono (判じ物) were immensely popular, and involved similar wordplay; see Rebus#Japan. Today the most often seen of these pictorial symbols is a picture of a sickle, a circle, and the letter nu (), read as kama-wa-nu (鎌輪ぬ, sickle circle nu), interpreted as kamawanu (構わぬ), the old-fashioned form of kamawanai (構わない, don't worry, doesn't matter). This is known as the kamawanu-mon (鎌輪奴文, kamawanu sign), and dates to circa 1700,[4] being used in kabuki since circa 1815.[5][6]
