A seal, in an East and Southeast Asian context, is a general name for printing stamps and impressions thereof which are used in lieu of signatures in personal documents, office paperwork, contracts, art, or any item requiring acknowledgement or authorship. In the western world they were traditionally known by traders as chop marks or simply chops. The process started in China and soon spread across East Asia. China, Japan and Korea currently use a mixture of seals and hand signatures, and, increasingly, electronic signatures.
Chinese seals are typically made of stone, sometimes of metals, wood, bamboo, plastic, or ivory, and are typically used with red ink or cinnabar paste (Chinese: 朱砂; pinyin: zhūshā). The word 印 ("yìn" in Mandarin, "in" in Japanese and Korean) specifically refers to the imprint created by the seal, as well as appearing in combination with other morphemes in words related to any printing, as in the word "印刷", "printing", pronounced "yìnshuā" in Mandarin, "insatsu" in Japanese. The colloquial name chop, when referring to these kinds of seals, was adapted from the Hindi word chapa and from the Malay word cap, meaning stamp or rubber stamps. In Japan, seals (hanko) have historically been used to identify individuals involved in government and trading from ancient times. The Japanese emperors, shōguns, and samurai had their personal seals pressed onto edicts and other public documents to show authenticity and authority. Even today Japanese citizens' companies regularly use name seals for the signing of a contract and other important paperwork.
There are many classes of personal seals.

There are two types of seal paste depending on what base material they are made of. The standard colour is vermilion red (or lighter or darker shades of red) but other colours can be used such as black, navy, etc. for specific purposes.
Plant-based paste tends to dry more quickly than silk-based pastes because the plant extract does not hold onto the oil as tightly as silk. Depending on the paper used, plant pastes can dry in 10 to 15 minutes. The more absorbent the paper is, the faster it dries as the paper absorbs most of the oil. Also, plant pastes tend to smudge more easily than silk pastes due to the loose binding agent.
The paste is kept covered after it has been used, in its original container (be it plastic or ceramic). It is kept in an environment away from direct sunlight and away from intense heat to prevent it from drying out. The paste for silk based pastes need to be stirred with a spatula every month or so to avoid the oil sinking down and drying out the paste as well as to prepare it for use. A good paste would produce a clear impression in one go; if the impression is not clear requiring further impressions then it indicates that the paste is either too dry or the cinnabar has been depleted.
When the seal is pressed onto the printing surface, the procedure differs according to plant or silk based paste. For silk based paste, the user applies pressure, often with a specially made soft, flat surface beneath the paper. For plant based paste, the user simply applies light pressure. As lifting the seal vertically away from its imprint may rip or damage paper, the seal is usually lifted off one side at a time, as if bent off from the page. After this, the image may be blotted with a piece of paper to make it dry faster, although this may smudge it. Usually there needs to be a pile of soft felt or paper under the paper to be imprinted for a clear seal impression.
Many people in China possess a personal name seal. Artists, scholars, collectors and intellectuals may possess a full set of name seals, leisure seals, and studio seals. A well-made seal made from semi-precious stones can cost between 400 and 4000 yuan (about to 60 to 600 United States dollars in 2021).
Seals are still used for official purposes in a number of contexts. When collecting parcels or registered post, the name seal serves as an identification, akin to a signature. In banks, traditionally the method of identification was also by a seal. Seals remain the customary form of identification on cheques in mainland China and Taiwan. Today, personal identification is often by a hand signature accompanied by a seal imprint. Seals can serve as identification with signatures because they are difficult to forge (when compared to forging a signature) and only the owner has access to his own seal.
Seals are also often used on Chinese calligraphy works and Chinese paintings, usually imprinted in such works in the order (from top to bottom) of name seal, leisure seal(s), then studio seal. Owners or collectors of paintings or books will often add their own studio seals to pieces they have collected. This practice is an act of appreciation towards the work. Some artworks have had not only seals but inscriptions of the owner on them; for example, the Qianlong Emperor had as many as 20 different seals for use with inscriptions on paintings he collected. Provided that it is tastefully done (for example, not obscuring the body of the painting, appropriate inscription, fine calligraphy, etc.), this practice does not devalue the painting but could possibly enhance it by giving it further provenance, especially if it is a seal of a famous or celebrated individual who possessed the work at some point.
Seals are usually carved by specialist seal carvers, or by the users themselves. Specialist carvers carve the user's name into the stone in one of the standard scripts and styles described above, usually for a fee. On the other hand, some people take to carving their own seals using soapstone and fine knives, which are widely available and is cheaper than paying a professional for expertise, craft and material. Results vary, but it is possible for individuals to carve perfectly legitimate seals for themselves.
As a novelty souvenir, seal carvers also ply tourist business at Chinatowns and tourist destinations in China. They often carve on-the-spot or translations of foreign names on inexpensive soapstone, sometimes featuring Roman characters. Though such seals can be functional, they are typically nothing more than curios and may be inappropriate for serious use and could actually devalue or deface serious works of art.
Determining which side of the seal should face up may be done in a number of ways: if there is a carving on top, the front should face the user; if there is an inscription on the side, it should face to the left of the user; if there is a dot on the side, it should face away from the user.
Once seals are used, as much paste as possible is wiped from the printing surface and off the edges with a suitable material. The seals are kept in a constant environment, especially seals made of sandalwood or black ox horn. Tall thin seals are best kept on their sides, in case they should wobble and fall down. More important seals, such as authority and society seals are encased or wrapped in a golden silk cloth to add more protection.
In Hong Kong, seals have fallen out of general use, as signatures are often required. In the past, seals have been used by businesses on documents related to transactions. In addition, seals have been used in lieu of a signature for the city's illiterate population.
In Japan, seals in general are referred to as inkan (印鑑) or hanko (判子). Inkan is the most comprehensive term; hanko tends to refer to seals used in less important documents.
The first evidence of writing in Japan is a hanko dating from AD 57, made of solid gold given to the ruler of Nakoku by Emperor Guangwu of Han, called King of Na gold seal. At first, only the Emperor and his most trusted vassals held hanko, as they were a symbol of the Emperor's authority. Noble people began using their own personal hanko after AD 750, and samurai began using them sometime during the Feudal Period. Samurai were permitted exclusive use of red ink. After modernization began in 1870, hanko came into general use throughout Japanese society.
Government offices and corporations usually have inkan specific to their bureau or company and follow the general rules outlined for jitsuin with the following exceptions. In size, they are comparatively large, measuring 2 to 4 inches (5.1 to 10.2 cm) across. Their handles are often ornately carved with friezes of mythical beasts or hand-carved hakubun inscriptions that might be quotes from literature, names and dates, or original poetry. The Privy Seal of Japan is an example; weighing over 3.55 kg and measuring 9.09 cm it is used for official purposes by the Emperor.
Some seals have been carved with square tunnels from handle to underside, so that a person can slide their inkan into the hollow, thus signing a document with both their name and the business's (or bureau's) name. These seals are usually stored in jitsuin-style boxes under high security except at official ceremonies, at which they are displayed on ornate stands or in their boxes.
For personal use, there are at least four kinds of seals. In order from most formal/official to least, they are jitsuin, ginkō-in, mitome-in, and gagō-in.
A jitsuin (実印) is an officially registered seal. A registered seal is needed to conduct business and other important or legally binding events. A jitsuin is used when purchasing a vehicle, marrying, or purchasing land, for example.
The size, shape, material, decoration, and lettering style of jitsuin are closely regulated by law. For example, in Hiroshima, a jitsuin is expected to be roughly 1⁄2 to 1 inch (1.3 to 2.5 cm), usually square or (rarely) rectangular but never round, irregular, or oval. It must contain the individual's full family and given name, without abbreviation. The lettering must be red with a white background (shubun), with roughly equal width lines used throughout the name. The font must be one of several based on ancient historical lettering styles found in metal, woodcarving, and so on. Ancient forms of ideographs are commonplace. A red perimeter must entirely surround the name, and there should be no other decoration on the underside (working surface) of the seal. The top and sides (handle) of the seal may be decorated in any fashion from completely undecorated to historical animal motifs to dates, names, and inscriptions.
Throughout Japan, rules governing jitsuin design are so stringent and each design is unique so the vast majority of people entrust the creation of their jitsuin to a professional, paying upward of US$20 and more often closer to US$100, and using it for decades. People desirous of opening a new chapter in their lives—say, following a divorce, death of a spouse, a long streak of bad luck, or a change in career—will often have a new jitsuin made.
The material is usually a high quality hard stone or, far less frequently, deerhorn, soapstone, or jade. It is sometimes carved by machine. When it's carved by hand, an intō ("seal-engraving blade"), a mirror, and a small specialized wooden vice are used. An intō is a flat-bladed pencil-sized chisel, usually round or octagonal in cross-section and sometimes wrapped in string to give the handle a non-slip surface. The intō is held vertically in one hand, with the point projecting from one's fist on the side opposite one's thumb. New, modern intō range in price from less than US$1 to US$100.
The jitsuin are kept in secure places such as bank vaults. or hidden in one's home. They are usually stored in thumb-sized rectangular boxes made of cardboard covered with embroidered green fabric outside and red silk or red velvet inside, held closed by a white plastic or deerhorn splinter tied to the lid and passed through a fabric loop attached to the lower half of the box. Because of the superficial resemblance to coffins, they are often called "coffins" in Japanese by enthusiasts and hanko boutiques. The paste is usually stored separately.
A ginkō-in (銀行印) is used specifically for banking; ginkō means "bank". A person's savings account passbook contains an original impression of the ginkō-in alongside a bank employee's seal. Rules for the size and design vary somewhat from bank to bank; generally, they contain a Japanese person's full name. A Westerner may be permitted to use a full family name with or without an abbreviated given name, such as "Smith", "Bill Smith", "W Smith" or "Wm Smith" in place of "William Smith". The lettering can be red or white, in any font, and with artistic decoration.
Since mass-produced ginkō-in offer no security, people either have them custom-made by professionals or make their own by hand. They were traditionally made of wood or stone; more recently of ivory, and carried in a variety of thumb-shape and -size cases resembling cloth purses or plastic pencil cases. They are usually hidden carefully in the owner's home.
Banks always provide stamp pads or ink paste, in addition to dry cleaning tissues. The banks also provide small plastic scrubbing surfaces similar to small patches of red artificial grass. These are attached to counters and used to scrub the accumulated ink paste from the working surface of customers' seals.
A mitome-in (認印) is a moderately formal seal typically used for signing for postal deliveries, signing utility bill payments, signing internal company memos, confirming receipt of internal company mail, and other low-security everyday functions.
Mitome-in are commonly stored in low-security, high-utility places such as office desk drawers and in the anteroom (genkan) of a residence.
A mitome-in's form is governed by fewer customs than jitsuin and ginkō-in. However, mitome-in adhere to a handful of strongly observed customs. The size is the attribute most strongly governed by social custom. It is usually the size of an American penny or smaller. A male's is usually slightly larger than a female's, and a junior employee's is always smaller than his bosses' and his senior co-workers', in keeping with office social hierarchy. The mitome-in always has the person's family name and usually does not have the person's given name (shita no namae). They are often round or oval, but square ones are not uncommon, and rectangular ones are not unheard-of. They are always geometric figures. They can have red lettering on a blank field (shubun) or the opposite (hakubun). Borderlines around their edges are optional.
Plastic mitome-in in popular Japanese names can be obtained from stationery stores for less than US$1, though ones made from inexpensive stone are also very popular. Inexpensive prefabricated seals are called sanmonban (三文判). Prefabricated rubber stamps are unacceptable for business purposes.
Mitome-in and lesser seals are usually stored in inexpensive plastic cases, sometimes with small supplies of red paste or a stamp pad included.
Most Japanese also have a less formal seal used to sign personal letters or initial changes in documents; this is referred to by the broadly generic term hanko. They often display only a single hiragana, kanji ideograph, or katakana character carved in it. They are as often round or oval as they are square. They vary in size from 0.5-to-1.5-centimetre wide (0.20 to 0.59 in); women's tend to be small.
Gagō-in (雅号印) are used by graphic artists to both decorate and sign their work. The practice goes back several hundred years. The signatures are frequently pen names or nicknames; the decorations are usually favorite slogans or other extremely short phrases. A gago in can be any size, design, or shape. Irregular naturally occurring outlines and handles, as though a river stone were cut in two, are commonplace. The material may be anything, though in modern times soft stone is the most common and metal is rare.
Traditionally, inkan and hanko are engraved on the end of a finger-length stick of stone, wood, bone, or ivory, with a diameter between 25 and 75 millimetres (0.98 and 2.95 in). Their carving is a form of calligraphic art. Foreign names may be carved in rōmaji, katakana, hiragana, or kanji. Inkan for standard Japanese names may be purchased prefabricated.
Almost every stationery store, discount store, large book store, and department store carries small do-it-yourself kits for making hanko. These include instructions, hiragana fonts written forward and in mirror-writing (as they'd appear on the working surface of a seal), a slim in tou chisel, two or three grades of sandpaper, slim marker pen (to draw the design on the stone), and one to three mottled, inexpensive, soft square green finger-size stones.
In modern Japan, most people have several inkan.
A certificate of authenticity is required for any hanko used in a significant business transaction. Registration and certification of an inkan may be obtained in a local municipal office (e.g., city hall). There, a person receives a "certificate of seal impression" known as inkan tōroku shōmei-sho (印鑑登録証明書).
The increasing ease with which modern technology allows hanko fraud is beginning to cause some concern that the present system will not be able to survive.
Signatures are not used for most transactions, but in some cases, such as signing a cell phone contract, they may be used, sometimes in addition to a stamp from a mitome-in. For these transactions, a jitsuin is too official, while a mitome-in alone is insufficient, and thus signatures are used.
Chinese style seals were also utilized by the Ryūkyū Kingdom.
During 2020 the Japanese government has been attempting to discourage the use of seals, because the practice requires generation of paper documents that interfere with electronic record-keeping and slow digital communications. The delay has been most pressing in infectious disease reporting during the COVID-19 pandemic: Officials found it took up to three days between a case of COVID-19 being discovered and it being reported to the public. Japanese prime minister Yoshihide Suga has set the digitalization of the bureaucracy and ultimately of Japan's entire society as a key priority. He aims to establish a new digital agency to put the idea into practice.
The seal was first introduced to Korea in approximately 2nd century BC. The remaining oldest record of its usage in Korea is that kings of Buyeo used a royal seal (oksae: 옥새, 玉璽) which bore the inscription of Seal of the King of Ye (濊王之印, 예왕지인). The use of seals became popular during the Three Kingdoms of Korea period.
In the case of State Seals in monarchic Korea, there were two types in use: Gugin (국인, 國印) which was conferred by the Emperor of China to Korean kings, with the intent of keeping relations between two countries as brothers (Sadae). This was used only in communications with China and for the coronation of kings. Others, generally called eobo (어보, 御寶) or eosae (어새, 御璽), are used in foreign communications with countries other than China, and for domestic uses. With the declaration of establishment of Republic of Korea in 1948, its government created a new State Seal, guksae (국새, 國璽) and it is used in promulgation of constitution, designation of cabinet members and ambassadors, conference of national orders and important diplomatic documents.
Seals were also used by government officials in documents. These types of seals were called gwanin (관인, 官印) and it was supervised by specialist officials.
Seals are still commonly used in South Korea. Most Koreans have personal seals, and every government agency and commercial corporation has its own seals to use in public documents. While signing is also accepted, many Koreans think it is more formal to use seals in public documents. In 2008, the Constitutional Court of South Korea upheld a Supreme court judgement that a signed and handwritten will which lacked a registered seal was invalid.
Personal seals (Korean: 도장; RR: dojang) in Korea can be classified by their legal status. Ingam (인감, 印鑑) or sirin (실인, 實印), meaning registered seal, is the seal which is registered to local office. By registering the seal, a person can issue a "certificate of seal registration" (Korean: 인감증명서; Hanja: 印鑑證明書; RR: ingam-jungmyeong-seo) which is a required document for most significant business transactions and civil services.
The legal system of registered seals was introduced by the Japanese colonial government in 1914. While it was scheduled to be completely replaced by the electronic certification system in 2013 in order to counter fraud, ingam still remains an official means of verification for binding legal agreement and identification. The government did pass the 'Act on Confirmation, etc. of Personal Signature (본인서명사실 확인 등에 관한 법률)' in 2012, which allows pre-registered handwritten signatures to have the same legal effect as ingam.
While ingam is used in important business, other dojangs are used in everyday purpose such as less-significant official transactions. Thus most Koreans have more than two seals.
In traditional arts, like in China and Japan, an artist of Chinese calligraphy and paintings would use seals (generally leisure seals and studio seals) to identify their work. These types of seals were called Nakkwan (낙관, 落款). As seal-carving itself was considered a form of art, many artists carved their own seals. Seals of Joseon-period calligraphist and natural historian Kim Jung-hee (aka Wandang or Chusa) are considered as antiquary.
Korean seals are made of wood, jade, or sometimes ivory for more value. State Seals were generally made of gold or high-quality jade. Rare cases of bronze or steel seals exist.
The Philippines also had a sealing culture prior to Spanish colonization. However, when the Spaniards succeeded in colonizing the islands, they abolished the practice and burned all documents they captured from the natives while forcefully establishing a Roman Catholic-based rule. Records on Philippine seals were forgotten until in the 1970s when ancient seals made of ivory were found in an archaeological site in Butuan. The seal, now known as the Butuan Ivory Seal, has been declared a National Cultural Treasure. The seal is inscribed with the word "Butwan" through a native suyat script. The discovery of the seal proved the theory that pre-colonial Filipinos, at least in coastal areas, used seals on paper. Before the discovery of the seal, it was only thought that ancient Filipinos used bamboo, metal, bark, and leaves for writing. The presence of paper documents in the classical era of the Philippines is also backed by a research of Dr. H. Otley Beyer, father of Philippine anthropology, stating that Spanish friars 'boasted' about burning ancient Philippine documents with suyat inscriptions, one of the reasons why ancient documents from the Philippines are almost non-existent now. The ivory seal is now housed at the National Museum of the Philippines. Nowadays, younger generations are trying to revive the usage of seals, notably in signing pieces of art such as drawings, paintings, calligraphy, and literary works.

The seal is used to a lesser extent in Vietnam by authorised organisations and businesses, and also traditional Vietnamese artists. It was more common in Vietnam prior to French rule, when thereafter the practice of signature became a commonality, although western-like signatures are usually seen as having less authority in a corporate situation.
While Chinese-style seals are typically used in China, Japan, and Korea, they are occasionally used outside East Asia. For example, the rulers of the Ilkhanate, a Mongol khanate established by Hulagu Khan in Persia, used seals containing Chinese characters in their diplomatic letters, such as the letter from Arghun to French King Philip IV and the letter from Ghazan to Pope Boniface VIII. These seals were sent by the emperors of the Yuan dynasty, a Mongol-ruled dynasty of China, especially by Kublai Khan and his successor Emperor Chengzong.
