Kanji are not just characters, but a complex system of meaning and sound.

In short: Kanji are logographic characters adapted from Chinese that have shaped Japanese language and culture for centuries. Far from a static alphabet, they function through dual reading systems—kun'yomi and on'yomi—and are governed by evolving government lists that balance tradition with the practical needs of modern literacy and digital communication.

The integration of Chinese characters into Japan began around the 5th century CE, though archaeological evidence like inkstone artifacts suggests earlier contact. Initially used to write Sinitic texts, these characters were eventually adapted to record the vernacular Japanese language. This evolution produced kana syllabaries: hiragana, historically associated with women's writing at the Heian court, and katakana, which monks developed by simplifying character elements. Together, these systems form the modern Japanese writing landscape.

Kanji are categorized by their readings: on'yomi, derived from Chinese pronunciations, and kun'yomi, based on native Japanese words. A single character can possess multiple readings depending on context. For example, the character 生 features two on readings and ten kun readings or inflected forms. This complexity is managed through official guidelines, such as the jōyō kanji list, which currently includes 2,136 characters for general social use, and the jinmeiyō kanji list, which permits 863 additional characters for personal names.

Modern orthography reflects a history of reform. Following the Meiji Restoration, Japan sought to simplify character use, leading to the creation of shinjitai, or new character forms. The 1946 reforms, enacted during the Allied occupation, further standardized education and communication. Today, digital encoding standards like JIS X 0213 and Unicode have largely replaced the need for gaiji—user-defined characters—which once posed significant challenges for information interchange. While the Dai Kan-Wa Jiten lists about 50,000 characters, the vast majority are rarely used, highlighting the distinction between comprehensive historical records and the practical, everyday application of the language.
