A large part of the difficulty of learning Japanese has to do with learning its writing system. Put simply, it is a lovely mess.
The modern Japanese writing system started around the 6th century, with the borrowing of the Chinese characters; these characters are called kanjis (漢字), which means ‘Han’s characters’, with the Han people being the Chinese. Kanjis represent ideas, e.g., 人 represents a man (it looks like a standing man), while 川 represents a river (it looks like a stream). Hence, kanjis are ideograms. Kanjis are used to write nouns, the stems of verbs and adjectives, and adverbs.In the image on the right, the first kanji, 日 (ni), stands for ‘sun’; the second one, 本 (hon), means ‘origin’; and the third one, 語 (go), means ‘language’. 日本 (ni-hon) is the place where the sun originates (or rises), as seen from mainland Asia, i.e., Japan; hence, 日本語 (ni-hon-go) is ‘the language of the place where the sun rises’ or ‘the language of Japan’, i.e., the Japanese language.
Many kanjis are difficult to tell apart, most kanjis are difficult to write, and there are many kanjis; to be able to read a newspaper, we need to learn about 2,000 kanjis, but there are thousands more, around 40,000-50,000. Daunting as all of this sounds, the number of kanjis is not the main difficulty of learning them. What makes them challenging is that their meaning and sound changes depending on the context. For example, 日, the kanji for ‘sun’ sounds ‘ni’ when we use it to write 日本 (ni-hon, Japan); however, 日 appears two times in the word 日曜日 (nichi-you-bi, Sunday), and it does not sound ‘ni’ in either of them: the first time it sounds ‘nichi’, and the second time it sounds ‘bi’. In other contexts, 日 will have other meanings and sounds. These changes are not just simple variations in pronunciation, but completely different sounds. To continue with our example, the words for ‘today’ and ‘tomorrow’ are 今日, pronounced ‘kyou’, and 明日, pronounced ‘ashita’, i.e., these two words use the kanji 日, but the sounds ‘ni’, ‘nichi’ or ‘bi’ are nowhere to be found.
Part of the reason for these variations is that some pronunciations come from the original Japanese sound of the word, while others come from the Chinese sound of the word. The ‘native reading’ of a kanji, or kun-yomi, is the Japanese sound of the thing that the character represents, while its ‘sound reading’, or on-yomi, is the Chinese sound. For example, ‘person’ in Japanese is ‘hito’, and in Chinese is ‘ren’; hence, the kanji for person, 人, has the kun-yomi ‘hito’, and the on-yomis ‘jin’ and ‘nin’, which sound like ‘ren’ [jisho.com]. We usually use kun-yomis when the word is by itself, e.g., ‘sono hito’ (その人 – that person), and on-yomis when the kanji is part of a compound word, e.g., ‘america-jin’ (アメリカ人 – American person), or ‘san-nin’ (三人 – three persons). In general, though, this behavior of the Japanese language is similar to English having words from different origins meaning the same thing; for example, ‘water’ (germanic), ‘aqua’ (latin), and ‘hydro'(greek) all mean water, but in different contexts, and ‘aqua’ and ‘hydro’ usually appear only as parts of compound words, like in ‘aquamarine’, or ‘hydroelectric’.
Another reason for a change in pronunciation is to make the sound ‘get along’ with the sounds that precede it or follow it; technically this is called euphony. For example, the kanji 本, hon, which means ‘origin’ when we write ‘Japan’, is also used as the counter for long thin objects, like bottles, cigarettes, or arrows, but depending on the number of items, it is pronounced ‘hon’, ‘ppon’, or ‘bon’: ‘ippon’ (一本) might be one bottle, ‘nihon’ (二本) two bottles, and ‘sanbon’ (三本) three bottles. Notice that now we have two ways to write ‘nihon’: 日本, meaning ‘Japan’, and 二本, meaning ‘two long thin objects’. Hence, we really cannot write the word ‘ni-hon’ using kanjis unless we know the context in which we are writing it.
Yet another reason for the change of pronunciation is a common softening of ‘hard’ consonants when they become part of a word, e.g., “h” becomes “b”, “k” becomes “g”, “s” becomes “z”, etc. For example, the word ‘hito’ (人, person) might turn into ‘bito’ when it becomes part of a word: ‘koi-bito’ (恋人, lover), or ‘mura-bito’ (村人, villager).
This variation of the meaning and sound of a kanji depending on the context in which it appears is what makes kanjis really challenging to learn. In essence, we have to memorize each different kanji in each different context in which it may appear.
The kanjis were (and are) difficult to learn, and only the educated people were able to read and write them. However, the Japanese language has only about 100 sounds, so someone figured out that we could take kanjis that ‘sounded’ like one of the native Japanese sounds, and make a new writing system with simplified versions of those few kanjis. This was the origin of hiragana.Hiragana characters are curvilinear. Unlike the english alphabet that encodes individual sounds (e.g., ‘n’ and ‘i’), hiragana characters encode syllables (e.g., ‘ni’), so hiragana is not an alphabet but a syllabary. The only characters that are encoded by themselves are the five vowels – a, i, u, e, o (as they are ordered in Japanese), and the consonant ‘n’.
We use hiragana to write all the particles (things like ‘to’, ‘from’, ‘with’, etc.) and the conjugations of verbs and adjectives. We also use it to write many words of frequent use, like greetings. However, since hiragana covers all the sounds of the Japanese language, we can use it to ‘spell out’ any Japanese word, and thus, it is frequently used to write children’s books.
Katakana (カタカナ)A second syllabary, called katakana, is mostly a mirror image of hiragana so, in theory, either syllabary could be used to write anything in Japanese. These two syllabaries – hiragana and katakana, together, are called ‘the kanas’. Unlike the round and soft characters of hiragana, katakana characters tend to be linear and angular.
We use katakana to write
- foreign words, e.g., ramen (of Chinese origin) is ラーメン (ra-a-me-n)
- onomatopoeias, e.g., the meow of a cat is ニャーニャー (nya-a-nya-a)
- mimetic words, e.g., the sound of a heart pounding is ドキドキ (do-ki-do-ki)
- scientific names, e.g., a quasar is クエーサー (ku-e-e-sa-a)
- and to add emphasis
Romaji (ローマ字)People that are learning Japanese sometimes write the Japanese words using the Roman alphabet, e.g., we would write ‘nihongo’ (the Japanese language) instead of にほんご, or 日本語; this use of the roman alphabet to write Japanese sounds is called ‘romaji’, lit. ‘Roman character’.
Romaji is a reencoding of the way that the word is written in hiragana or katakana. For example, Tokyo is written in hiragana as とうきょう, so the romaji version of Tokyo is the syllable-by-syllable translation of とうきょう, i.e., to-u-kyo-u. To get the correct pronunciation of the word, i.e., to-o-kyo-o, we have to further know the rule that in Japanese an ‘o’ followed by a ‘u’ means that the ‘o’ has to be doubled, i.e., ‘ou’ sounds ‘oo’. Still, the use of roman characters in romaji goes a long way to indicate how a Japanese word sounds.
The problem is that the Japanese do not use romaji at all, so learning Japanese using romaji can be a hindrance. Romaji indicates how to pronounce a word without having to learn the kanas but, if we are serious about learning Japanese, learning the kanas is a small investment for a large return.
Japanese people use the roman alphabet when they want to write the original foreign version of the word. Sometimes they do this to create an effect, other times for clarification. Likewise, Arabic numerals (1, 2, 3, 4, …) have become as common as the kanji numerals (一, 二, 三, 四, …).
We often find the roman alphabet at airports, train stations, and other places frequented by tourists. Sometimes vowels have a macron: ā, ī, ū, ē, ō; this indicates that we need to double the vowel. For example, Tokyo, written in romaji as toukyou, is pronounced to-o-kyo-o, so the roman alphabet version of the word would be written in the sign as Tōkyō:
Unlike the romaji version of the word, the ō does not give a hint of how the word is actually written in Japanese, but only of how it is pronounced. This ō sound might come from a duplication of the o vowel, like in oosaka (ōsaka); or from an o followed by a u, like in the sign’s yuurakuchou (Yūrakuchō), or like both ō’s in toukyou (Tōkyō). Yūrakuchō also shows a ū representing a double u sound, i.e, yuurakuchou.
As a second example, Osaka is actually written and pronounced おおさか (o-o-sa-ka), so we write it in romaji as ‘oosaka’, and in roman alphabet as Ōsaka; Kobe is こうべ (ko-u-be), so we write it in romaji as ‘koube’ , and in roman alphabet as Kōbe:
Selecting the script
Sometimes, the writer might choose to write a word that is usually written in one script, using another one; this choice is similar to the choice of writing an English word in upper-case, or italics, or bold, or in a different font, to convey something. As an example, in English, robot-talk might be written in block letters, to indicate something ‘mechanical’ and ‘digital’. The following is a relevant quote from ‘kandyman’:
(The) choice of script in Japanese writing is often a stylistic attempt by a writer to convey some non-standard subliminal meaning. There have been some interesting analyses on this topic done over the years. Just to give you an idea of some of the findings, one study found that certain characteristics were often attributed to script usage, as follows:
Hiragana: feminine, soft, smooth, round, tender, simple, childish, lovely, elegant, etc.
Katakana: novel, foreign, emphasizing, hard, fake, male, futuristic, sharp, jarring, angular, etc.
Kanji: scientific, rigid, masculine, formal, hard, difficult, intellectual, visual, substantial, etc.
