Kanji (help·info) (漢字) are the Chinese characters that are used in the modern Japanese logographic writing system along with hiragana (ひらがな, 平仮名), katakana (カタカナ, 片仮名), Arabic numerals, and the occasional use of the Latin alphabet (also known as Rōmaji). The Japanese term kanji (漢字) literally means "Han characters".

Chinese characters first came to Japan on articles imported from China. An early instance of such an import was a gold seal given by the emperor of the Eastern Han Dynasty in 57 AD. It is not clear when Japanese people started to gain a command of Classical Chinese by themselves. The first Japanese documents were probably written by Chinese immigrants. For example, the diplomatic correspondence from King Bu of Wa to Emperor Shun of the Liu Song Dynasty in 478 has been praised for its skillful use of allusion. Later, groups of people called fuhito were organized under the monarch to read and write Classical Chinese. From the 6th century onwards, Chinese documents written in Japan tended to show interference from Japanese, suggesting the wide acceptance of Chinese characters in Japan.
The Japanese language itself had no written form at the time kanji were introduced. Originally texts were written in the Chinese language and would have been read as such. Over time, however, a system known as kanbun (漢文) emerged, which involved using Chinese text with diacritical marks to allow Japanese speakers to restructure and read Chinese sentences, by changing word order and adding particles and verb endings, in accordance with the rules of Japanese grammar.
Chinese characters also came to be used to write Japanese words, resulting in the modern kana syllabaries. A writing system called man'yōgana (used in the ancient poetry anthology Man'yōshū) evolved that used a limited set of Chinese characters for their sound, rather than for their meaning. Man'yōgana written in cursive style became hiragana, a writing system that was accessible to women (who were denied higher education). Major works of Heian era literature by women were written in hiragana. Katakana emerged via a parallel path: monastery students simplified man'yōgana to a single constituent element. Thus the two other writing systems, hiragana and katakana, referred to collectively as kana, are actually descended from kanji.
In modern Japanese, kanji are used to write parts of the language such as nouns, adjective stems and verb stems, while hiragana are used to write inflected verb and adjective endings (okurigana), particles, native Japanese words, and words where the kanji is too difficult to read or remember. Katakana is used for representing onomatopoeia, non-Japanese loanwords, certain naming, and for emphasis on certain words.
While kanji are essentially Chinese hanzi used to write Japanese, there are now significant differences between kanji and hanzi, including the use of characters created in Japan, characters that have been given different meanings in Japanese, and post World War II simplifications of the kanji.
Kokuji (国字, "national characters") are characters particular to Japan. Kokuji are also known as wasei kanji (和製漢字, "Chinese characters made in Japan"). There are hundreds of kokuji (see the sci.lang.japan FAQ: kokuji). Many are rarely used, but a number have become important additions to the written Japanese language. These include:
Some of them, like "腺", have been introduced to China.
In addition to kokuji, there are kanji that have been given meanings in Japanese different from their original Chinese meanings. These kanji are not considered kokuji but are instead called kokkun (国訓) and include characters such as:
Because of the way they have been adopted into Japanese, a single kanji may be used to write one or more different words (or, in most cases, morphemes). From the point of view of the reader, kanji are said to have one or more different "readings". Deciding which reading is meant depends on context, intended meaning, use in compounds, and even location in the sentence. Some common kanji have ten or more possible readings. These readings are normally categorized as either on'yomi (or on) or kun'yomi (or kun).
The on'yomi (音読み), the Sino-Japanese reading, is a Japanese approximation of the Chinese pronunciation of the character at the time it was introduced. Some kanji were introduced from different parts of China at different times, and so have multiple on'yomi, and often multiple meanings. Kanji invented in Japan would not normally be expected to have on'yomi, but there are exceptions, such as the character 働 "to work", which has the kun'yomi hataraku and the on'yomi dō, and 腺 "gland", which has only the on'yomi sen.
Generally, on'yomi are classified into four types:
Examples (rare readings in parentheses)
The most common form of readings is the kan-on one. The go-on readings are especially common in Buddhist terminology such as gokuraku 極楽 "paradise". The tō-on readings occur in some words such as isu 椅子 "chair" or futon 布団 "mattress".
In Chinese, most characters are associated with a single Chinese syllable. However, some homographs called 多音字 (pinyin: duōyīnzì) such as 行 (pinyin: háng or xíng) (Japanese: kō, gyō) have more than one reading in Chinese representing different meanings, which is reflected in the carryover to Japanese as well. Additionally, many Chinese syllables, especially those with an entering tone, did not fit the largely consonant-vowel (CV) phonotactics of classical Japanese. Thus most on'yomi are composed of two morae (syllables or beats), the second of which is either a lengthening of the vowel in the first mora, or one of the syllables ku, ki, tsu, chi, or syllabic n, chosen for their approximation to the final consonants of Middle Chinese. In fact, palatalized consonants before vowels other than i, as well as syllabic n, were probably added to Japanese to better simulate Chinese; none of these features occur in words of native Japanese origin.
On'yomi primarily occur in multi-kanji compound words (熟語 jukugo), many of which are the result of the adoption, along with the kanji themselves, of Chinese words for concepts that either did not exist in Japanese or could not be articulated as elegantly using native words. This borrowing process is often compared to the English borrowings from Latin and Norman French, since Chinese-borrowed terms are often more specialized, or considered to sound more erudite or formal, than their native counterparts. The major exception to this rule is family names, in which the native kun'yomi reading is usually used.
The kun'yomi (訓読み), Japanese reading, or native reading, is a reading based on the pronunciation of a native Japanese word, or yamatokotoba, that closely approximated the meaning of the Chinese character when it was introduced. As with on'yomi, there can be multiple kun readings for the same kanji, and some kanji have no kun'yomi at all.
For instance, the kanji for east, 東, has the on reading tō. However, Japanese already had two words for "east": higashi and azuma. Thus the kanji 東 had the latter readings added as kun'yomi. In contrast, the kanji 寸, denoting a Chinese unit of measurement (slightly over an inch), has no native Japanese equivalent; it only has an on'yomi, sun, with no native kun reading. Most kokuji, Japanese-created Chinese characters, only have kun readings.
Kun'yomi are characterized by the strict (C)V syllable structure of yamatokotoba. Most noun or adjective kun'yomi are two to three syllables long, while verb kun'yomi are usually between one and three syllables in length, not counting trailing hiragana called okurigana. Okurigana are not considered to be part of the internal reading of the character, although they are part of the reading of the word. A beginner in the language will rarely come across characters with long readings, but readings of three or even four syllables are not uncommon. 承る uketamawaru and 志 kokorozashi have five syllables represented by a single kanji, the longest readings of any kanji in the Jōyō character set.
In a number of cases, multiple kanji were assigned to cover a single Japanese word. Typically when this occurs, the different kanji refer to specific shades of meaning. For instance, the word なおす, naosu, when written 治す, means "to heal an illness or sickness". When written 直す it means "to fix or correct something". Sometimes the distinction is very clear, although not always. Differences of opinion among reference works is not uncommon; one dictionary may say the kanji are equivalent, while another dictionary may draw distinctions of use. As a result, native speakers of the language may have trouble knowing which kanji to use and resort to personal preference or by writing the word in hiragana. This latter strategy is frequently employed with more complex cases such as もと moto, which has at least five different kanji: 元, 基, 本, 下 and 素, three of which have only very subtle differences.
Local dialectical readings of kanji are also classified under kun'yomi, most notably readings for words in Ryukyuan languages.
There are many kanji compounds that use a mixture of on'yomi and kun'yomi, known as jūbako (重箱) or yutō (湯桶) words, which are themselves examples of this kind of compound (they are autological words): the first character of jūbako is read using on'yomi, the second kun'yomi, while it is the other way around with yutō. These are the Japanese form of hybrid words. Other examples include 場所 basho "place" (kun-on), 金色 kin'iro "golden" (on-kun) and 合気道 aikidō "the martial art Aikido" (kun-on-on).
Some kanji also have lesser-known readings called nanori (名乗り), which are mostly used for names (often given names), and are generally closely related to the kun'yomi. Place names sometimes also use nanori or, occasionally, unique readings not found elsewhere.
Gikun (義訓) or jukujikun (熟字訓) are readings of kanji combinations that have no direct correspondence to the characters' individual on'yomi or kun'yomi. For example, 今朝 ("this morning") is read neither as *ima'asa, the kun'yomi of the characters, nor *konchō, the on'yomi of the characters. Instead it is read as kesa—a native Japanese word with two syllables (which may be seen as a single morpheme, or as a fusion of kyō (previously kefu), "today", and asa, "morning").
Many ateji (kanji used only for their phonetic value) have meanings derived from their usage: for example, the now-archaic 亜細亜 ajia was formerly used to write "Asia" in kanji; the character 亜 now means Asia in such compounds as 東亜 tōa, "East Asia". From the written 亜米利加 amerika, the second character was taken, resulting in the semi-formal coinage 米国 beikoku, which literally translates to "rice country" but means "United States of America".
Although there are general rules for when to use on'yomi and when to use kun'yomi, the language is littered with exceptions, and it is not always possible for even a native speaker to know how to read a character without prior knowledge.
The rule of thumb is that kanji occurring in isolation, such as a character representing a single word unit, are typically read using their kun'yomi. They may be written with okurigana to mark the inflected ending of a verb or adjective, or by convention. For example: 情け nasake "sympathy", 赤い akai "red", 新しい atarashii "new ", 見る miru "(to) see", 必ず kanarazu "invariably". Okurigana is an important aspect of kanji usage in Japanese; see that article for more information on kun'yomi orthography
Kanji occurring in compounds are generally read using on'yomi, called 熟語 jukugo in Japanese. For example, 情報 jōhō "information", 学校 gakkō "school", and 新幹線 shinkansen "bullet train" all follow this pattern. This isolated kanji and compound distinction gives words for similar concepts completely different pronunciations. 東 "east" and 北 "north" use the kun readings higashi and kita, being stand-alone characters, while 北東 "northeast", as a compound, uses the on reading hokutō. This is further complicated by the fact that many kanji have more than one on'yomi: 生 is read as sei in 先生 sensei "teacher" but as shō in 一生 isshō "one's whole life". Meaning can also be an important indicator of reading; 易 is read i when it means "simple", but as eki when it means "divination", both being on'yomi for this character.
This rule of thumb has many exceptions. Kun'yomi compound words are not as numerous as those with on'yomi, but neither are they rare. Examples include 手紙 tegami "letter", 日傘 higasa "parasol", and the famous 神風 kamikaze "divine wind". Such compounds may also have okurigana, such as 空揚げ (also written 唐揚げ) karaage "fried food" and 折り紙 origami, although many of these can also be written with the okurigana omitted (for example, 空揚 or 折紙).
Similarly, some on'yomi characters can also be used as words in isolation: 愛 ai "love", 禅 Zen, 点 ten "mark, dot". Most of these cases involve kanji that have no kun'yomi, so there can be no confusion, although exceptions do occur. A lone 金 may be read as kin "gold" or as kane "money, metal"; only context can determine the writer's intended reading and meaning.
Multiple readings have given rise to a number of homographs, in some cases having different meanings depending on how they are read. One example is 上手, which can be read in three different ways: jōzu (skilled), uwate (upper part), or kamite (upper part). In addition, 上手い has the reading umai (skilled). Furigana is often used to clarify any potential ambiguities.
As stated above, 重箱 jūbako and 湯桶 yutō readings are also not uncommon. Indeed, all four combinations of reading are possible: on-on, kun-kun, kun-on and on-kun.
Some famous place names, including those of Tokyo (東京 Tōkyō) and Japan itself (日本 Nihon or sometimes Nippon) are read with on'yomi; however, the majority of Japanese place names are read with kun'yomi: 大阪 Ōsaka, 青森 Aomori, 箱根 Hakone. When characters are used as abbreviations of place names, their reading may not match that in the original. The Osaka (大阪) and Kobe (神戸) baseball team, the Hanshin (阪神) Tigers, take their name from the on'yomi of the second kanji of Ōsaka and the first of Kōbe. The name of the Keisei (京成) railway line, linking Tokyo (東京) and Narita (成田) is formed similarly, although the reading of 京 from 東京 is kei, despite kyō already being an on'yomi in the word Tōkyō.
Family names are also usually read with kun'yomi: 山田 Yamada, 田中 Tanaka, 鈴木 Suzuki. Given names, although they are not typically considered jūbako or yutō, often contain mixtures of kun'yomi, on'yomi and nanori: 大助 Daisuke [on-kun], 夏美 Natsumi [kun-on]. Being chosen at the discretion of the parents, the readings of given names do not follow any set rules and it is impossible to know with certainty how to read a person's name without independent verification. Parents can be quite creative, and rumours abound of children called 地球 Āsu and 天使 Enjeru, quite literally "Earth" and "Angel"; neither are common names, and have normal readings chikyū and tenshi respectively. Common patterns do exist, however, allowing experienced readers to make a good guess for most names.
Because of the ambiguities involved, kanji sometimes have their pronunciation for the given context spelled out in ruby characters known as furigana, (small kana written above or to the right of the character) or kumimoji (small kana written in-line after the character). This is especially true in texts for children or foreign learners and manga (comics). It is also used in newspapers for rare or unusual readings and for characters not included in the officially recognized set of essential kanji.
The number of possible characters is disputed. The Daikanwa Jiten contains about 50,000 characters, and this was thought to be comprehensive, but more recent mainland Chinese dictionaries contain 80,000 or more characters, many consisting of obscure variants. Most of these are not in common use in either Japan or China.
In 1946, following World War II, the Japanese government instituted a series of orthographic reforms. This was done with the goal of facilitating learning for children and simplifying kanji use in literature and periodicals. The number of characters in circulation was reduced, and formal lists of characters to be learned during each grade of school were established. Some characters were given simplified glyphs, called 新字体 (shinjitai). Many variant forms of characters and obscure alternatives for common characters were officially discouraged.
These are simply guidelines, so many characters outside these standards are still widely known and commonly used; these are known as hyōgaiji (表外字).
The Kyōiku kanji 教育漢字 ("education kanji") are 1006 characters that Japanese children learn in elementary school. The number was 881 until 1981. The grade-level breakdown of the education kanji is known as the Gakunen-betsu kanji haitōhyō (学年別漢字配当表), or the gakushū kanji.
The Jōyō kanji 常用漢字 are 1,945 characters consisting of all the Kyōiku kanji, plus an additional 939 kanji taught in junior high and high school. In publishing, characters outside this category are often given furigana. The Jōyō kanji were introduced in 1981. They replaced an older list of 1,850 characters known as the General-use kanji (tōyō kanji 当用漢字) introduced in 1946. The Japanese National Kanji Conference will add 11 new characters to the list, totaling 1,956, to be enforced by 2010[dead link]. These new characters are currently Jinmeiyō kanji and were previously not included in the Jōyō kanji, and are used to write prefecture names: 阪,熊,奈,岡,鹿,梨,阜,埼,茨,栃 and 媛.
Since September 27, 2004, the Jinmeiyō kanji 人名用漢字 consist of 2,928 characters, containing the Jōyō kanji plus an additional 983 kanji found in people's names. There were only 92 kanji in the original list published in 1952, but new additions have been made frequently. Sometimes the phrase Jinmeiyō kanji refers to all 2,928, and sometimes it only refers to the 983 that are only used for names.
Jinmeiyō kanji literally translates to "Chinese characters for use in personal names".
Hyōgaiji (表外字 "unlisted characters" ) are any kanji not contained in the jōyō kanji and jinmeiyō kanji lists. These are generally written using traditional characters, but extended shinjitai forms exist.
The Japanese Industrial Standards for kanji and kana define character code-points for each kanji and kana, as well as other forms of writing such as the Latin alphabet, Cyrillic alphabet, Greek alphabet, Hindu-Arabic numerals, etc. for use in information processing. They have had numerous revisions. The current standards are:
Gaiji (外字), literally meaning "external characters", are kanji that are not represented in existing Japanese encoding systems. These include variant forms of common kanji that need to be represented alongside the more conventional glyph in reference works, and can include non-kanji symbols as well.
Gaiji can be either user-defined characters or system-specific characters. Both are a problem for information interchange, as the codepoint used to represent an external character will not be consistent from one computer or operating system to another.
Gaiji were nominally prohibited in JIS X 0208-1997, and JIS X 0213-2000 used the range of code-points previously allocated to gaiji, making them completely unusable. Nevertheless, they persist today with NTT DoCoMo's "i-mode" service, where they are used for emoji (pictorial characters).
Unicode allows for optional encoding of gaiji in private use areas.
Adobe's SING (Smart INdependent Glyphlets) technology allows the creation of customized gaiji.

A Chinese scholar Xu Shen (許慎), in the Shuōwén Jiězì (說文解字) ca. 100 CE, classified Chinese characters into six categories (Japanese: 六書 rikusho). The traditional classification is still taught but is problematic and no longer the focus of modern lexicographic practice, as some categories are not clearly defined, nor are they mutually exclusive: the first four refer to structural composition, while the last two refer to usage.
(For a table of all the kyōiku kanji (教育漢字) broken down by category see this page, from which the above description has been extracted.)
These characters are pictograms, sketches of the object they represent. For example, 目 is an eye, 木 is a tree, etc. (Shōkei 象形 is also the Japanese word for Egyptian hieroglyphs). The current forms of the characters are very different from the original, and it is now hard to see the origin in many of these characters. It is somewhat easier to see in seal script. These make up a small fraction of modern characters.
Shiji-moji are ideograms, often called "simple ideograms" or "simple indicatives" to distinguish them from compound ideograms (below). They are usually simple graphically and represent an abstract concept such as 上 "up" or "above" and 下 "down" or "below". These make up a tiny fraction of modern characters.
These are compound ideograms, often called "compound indicatives", "associative compounds", or just "ideograms". These are usually a combination of pictograms that combine iconicly to present an overall meaning. An example is the kokuji 峠 (mountain pass) made from 山 (mountain), 上 (up) and 下 (down). Another is 休 (rest) from 人 (person) and 木 (tree). These make up a tiny fraction of modern characters.
These phono-semantic or radical-phonetic compounds, sometimes called "semantic-phonetic", "semasio-phonetic", or "phonetic-ideographic" characters, are by far the largest category, making up about 90% of characters. Typically they are made up of two components, one of which suggests the general category of the meaning or semantic context, and the other approximates the pronunciation. (The pronunciation really relates to the original Chinese, and may now only be distantly detectable in the modern Japanese on'yomi of the kanji. The same is true of the semantic context, which may have changed over the centuries or in the transition from Chinese to Japanese. As a result, it is a common error in folk etymology to fail to recognize a phono-semantic compound, typically instead inventing a compound-indicative explanation.)
As examples of this, consider the kanji with the 言 shape: 語, 記, 訳, 説, etc. All are related to word/language/meaning. Similarly kanji with the 雨 (rain) shape (雲, 電, 雷, 雪, 霜, etc.) are almost invariably related to weather. Kanji with the 寺 (temple) shape on the right (詩, 持, 時, 侍, etc.) usually have an on'yomi of "shi" or "ji". Sometimes one can guess the meaning and/or reading simply from the components. However, exceptions do exist — for example, neither 需 nor 霊 have anything to do with weather (at least in their modern usage), and 待 has an on'yomi of "tai". That is, a component may play a semantic role in one compound, but a phonetic role in another.
This group have variously been called "derivative characters", "derivative cognates", or translated as "mutually explanatory" or "mutually synonymous" characters; this is the most problematic of the six categories, as it is vaguely defined. It may refer to kanji where the meaning or application has become extended. For example, 楽 is used for 'music' and 'comfort, ease', with different pronunciations in Chinese reflected in the two different on'yomi, gaku 'music' and raku 'pleasure'.
These are rebuses, sometimes called "phonetic loans". The etymology of the characters follows one of the pattern above, but the present-day meaning is completely unrelated to this. A character was appropriated to represent a similar sounding word. For example, 来 in ancient Chinese was originally a pictograph for 'wheat'. Its syllable was homophonous with the verb meaning 'to come' and the character is used for that verb as a result, without any embellishing 'meaning' element attached. The character for wheat 麦, originally meant 'to come', being a Keisei-moji having 'foot' at the bottom for its meaning part and 'wheat' at the top for sound. The two characters swapped meaning, so today the more common word has the simpler character. This borrowing of sounds has a very long history.
The iteration mark (々) is used to indicate that the preceding kanji is to be repeated, functioning similarly to a ditto mark in English. It is pronounced as though the kanji were written twice in a row, for example 色々 (iroiro "various") and 時々 (tokidoki "sometimes"). This mark also appears in personal and place names, as in the surname Sasaki (佐々木). This symbol is a simplified version of the kanji 仝 (variant of 同 dō "same").
Another frequently used symbol is ヶ (a small katakana "ke"), pronounced "ka" when used to indicate quantity (such as 六ヶ月, rokkagetsu "six months") or "ga" in place names like Kasumigaseki (霞ヶ関). This symbol is a simplified version of the kanji 箇.
Kanji, whose thousands of symbols defy ordering by convention such as is used with the Roman Alphabet, uses radical-and-stroke sorting to order a list of Kanji words. In this system, common components of characters are identified; these are called radicals in Chinese and logographic systems derived from Chinese, such as Kanji.
Characters are then grouped by their primary radical, then ordered by number of pen strokes within radicals. When there is no obvious radical or more than one radical, convention governs which is used for collation. For example, the Chinese character for "mother" (媽) is sorted as a thirteen-stroke character under the three-stroke primary radical (女) meaning "woman".
Japanese school children are expected to learn 1,006 basic kanji characters, the kyōiku kanji, before finishing the sixth grade. The order in which these characters are learned is fixed. The kyōiku kanji list is a subset of a larger list of 1,945 kanji characters known as the jōyō kanji, characters required for the level of fluency necessary to read newspapers and literature in Japanese. This larger list of characters is to be mastered by the end of the ninth grade. Schoolchildren learn the characters by repetition and radical.
Students studying Japanese as a foreign language are often required to acquire kanji without having first learned the vocabulary associated with them. Strategies for these learners vary from copying-based methods to mnemonic-based methods such as those used in James Heisig's series Remembering the Kanji. Other textbooks use methods based on the etymology of the characters, such as Mathias and Habein's The Complete Guide to Everyday Kanji and Henshall's A Guide to Remembering Japanese Characters. Pictorial mnemonics, as in the text Kanji Pict-o-graphix, are also seen.
The Japanese government provides the Kanji kentei (日本漢字能力検定試験 Nihon kanji nōryoku kentei shiken; "Test of Japanese Kanji Aptitude") which tests the ability to read and write kanji. The highest level of the Kanji kentei tests about 6,000 kanji.

Kanji is one of the three forms of Japan writing. A kanji is an ideogram: that is, a kind of simple picture. It is a symbol of an idea such as an object, thing or quality.
Kanji ideograms (or “characters”) were taken about 2000 years ago from Chinese characters, and many were gradually changed. The word “kanji” means “Han characters” (i.e. “Chinese characters”).
There are two other systems used to write in Japanese. These systems are called Hiragana and Katakana (together they are called “Kana”). They show how a word is pronounced because each character stands for a syllable (a, ka, sa, ta etc). Each kanji could also be written in kana, indeed they are in children’s books or books for foreigners learning Japanese.
Many words in Japanese can have more than one meaning, e.g. “hana” can mean “nose” or “flower”, but the kanji character for each is quite different. However, each kanji character can have several different pronounciations, according to which meaning (which “reading”) is intended.
Kanji was originally written to look like what it means, thus the Japanese symbol for mouth is 口 (which is said as "koo-chi"), and looks like a mouth. Another word, 山 (said as "ya-ma") means mountain. The Japanese have Kanji for many words. Many can be shown with just one Kanji, but sometimes two Kanji characters are combined to make new words, such as 山口 (yamaguchi), "mountain-mouth", meaning a cave. (That is also the surname of Olympic figure skater Kristi Yamaguchi, and the name of a prefecture).
Kanji is often combined with hiragana to show the grammatical meaning of the word. In English this would be done with endings (e.g. “act” (the verb), “action” (the noun) etc.
Many kanji characters can be pronounced in two different ways according to whether the word stands alone (this is called the “kun” reading, or “kun-yomi”), or whether it is combined with another word (this called the “on” reading or “on-yomi”). The kun reading is based on Japanese pronounciation, the on reading is based on Chinese pronounciation. For example, 山on its own is "yama" (the Japanese word for “mountain”). When it is combined with another word or name, it is pronounced "san" e.g. “Fuji-san” (“Mount Fuji”).
Kanji characters are classed on the basis of how many brush strokes they are made of. The simplest kanji have one stroke and the most complex may have up to 23 strokes.
There are many different Kanji, the exact number is not known but it is around 50,000. However, not all 50,000 are taught in schools. The government of Japan has set up a 1945 basic Kanji list (Jōyō Kanji) that those learning the language ought to know. They are the ones most commonly used in newspapers and magazines, along with street signs and store signs. Kanji takes many years to learn. By the end of his school years a pupil should know about 1.850 Kanji. A university graduate would need to know about 3000. If someone does not know the Kanji for a word, they can write it in Kana and it will be understood, but it is not the proper way to write it.
Here are sentences from other pages on Kanji, which are similar to those in the above article.
