Jōyō kanji in the context of "Jinmeiyō kanji"

The modern Japanese writing system uses a combination of logographic kanji, which are adopted Chinese characters, and syllabic kana. Kana itself consists of a pair of syllabaries: hiragana, used primarily for native or naturalized Japanese words and grammatical elements; and katakana, used primarily for foreign words and names, loanwords, onomatopoeia, scientific names, and sometimes for emphasis. Almost all written Japanese sentences contain a mixture of kanji and kana. Because of this mixture of scripts, in addition to a large inventory of kanji characters, the Japanese writing system is considered to be one of the most complicated currently in use.

Several thousand kanji characters are in regular use, which mostly originate from traditional Chinese characters. Others made in Japan are referred to as "Japanese kanji" (和製漢字, wasei kanji), also known as "[our] country's kanji" (国字, kokuji). Each character has an intrinsic meaning (or range of meanings), and most have more than one pronunciation, the choice of which depends on context. Japanese primary and secondary school students are required to learn 2,136 jōyō kanji as of 2010. The total number of kanji is well over 50,000, though this includes tens of thousands of characters only present in historical writings and never used in modern Japanese.

Kanji (/ˈkændʒi, ˈkɑːn-/; Japanese: 漢字, pronounced [kaɲ.dʑi] ,'Chinese characters') are logographic Chinese characters, adapted from Chinese script, used in the writing of Japanese. They comprised a major part of the Japanese writing system during the time of Old Japanese and are still used, along with the subsequently derived syllabic scripts of hiragana and katakana. The characters have Japanese pronunciations; most have two, with one based on the Chinese sound. A few characters were invented in Japan by constructing character components derived from other Chinese characters. After the Meiji Restoration, Japan made its own efforts to simplify the characters, now known as shinjitai, by a process similar to China's simplification efforts, with the intention to increase literacy among the general public. Since the 1920s, the Japanese government has published character lists periodically to help direct the education of its citizenry through the myriad Chinese characters that exist. There are nearly 3,000 kanji used in Japanese names and in common communication.

The term kanji in Japanese literally means "Han characters". Japanese kanji and Chinese hanzi (traditional Chinese: 漢字; simplified Chinese: 汉字; pinyin: hànzì; lit. 'Han characters') share a common foundation. The significant use of Chinese characters in Japan first began to take hold around the 5th century AD and has since had a profound influence in shaping Japanese culture, language, literature, history, and records. Inkstone artifacts at archaeological sites dating back to the earlier Yayoi period were also found to contain Chinese characters.

Japanese names (日本人の氏名、日本人の姓名、日本人の名前, Nihonjin no shimei, Nihonjin no seimei, Nihonjin no namae) in modern times consist of a family name (surname) followed by a given name. Japanese names are usually written in kanji, where the pronunciation follows a special set of rules. Because parents when naming children, and foreigners when adopting a Japanese name, are able to choose which pronunciations they want for certain kanji, the same written form of a name may have multiple readings. In exceptional cases, this makes it impossible to determine the intended pronunciation of a name with certainty. Even so, most pronunciations chosen for names are common, making them easier to read. While any jōyō kanji (with some exceptions for readability) and jinmeiyō kanji may be used as part of a name, names may be rejected if they are believed to fall outside what would be considered an acceptable name by measures of common sense.

Japanese names may be written in hiragana or katakana, the Japanese language syllabaries for words of Japanese or foreign origin, respectively. As such, names written in hiragana or katakana are phonetic rendering and lack meanings that are expressed by names written in the logographic kanji.

The jōyō kanji (常用漢字; Japanese pronunciation: [dʑoːjoːkaꜜɲdʑi], lit. "regular-use kanji") system of representing written Japanese currently consists of 2,136 characters.

Kanji (/ˈkændʒi, ˈkɑːn-/; Japanese: 漢字, pronounced [kaɲ.dʑi] , 'Han characters') are logographic Chinese characters, historically adapted from Chinese writing scripts, used in writing of Japanese. They comprised a major part of the Japanese writing system during the time of Old Japanese and are still used today, along with the subsequently derived syllabic (phonographic) scripts of hiragana and katakana. Most Kanji characters have two pronunciations: kun'yomi, based on the sounds of vernacular Japanese, where the Kanji is often phonetically transcribed with furigana; and on'yomi, based on the imitation of the original Middle Chinese sound when it was borrowed from written Chinese. Some Kanji characters were indigenously invented in Japan by constructing character components derived from other Chinese characters.

After the Meiji Restoration, Japan made its own efforts to simplify the Kanji characters, now known as shinjitai (新字体; 'new character form'), by a process similar to China's simplification efforts, with the intention to increase literacy among the general public. Since the 1920s, the Japanese government has published character lists periodically to help direct the education of its citizenry through the myriad Chinese characters that exist. There are nearly 3,000 kanji used in Japanese names and in common communication.
