kanji
= Chinese characters used in Japanese writing
漢字 (kanji) are the logographic characters borrowed from Chinese that form one of the three scripts in the Japanese writing system. Unlike hiragana and katakana, each kanji carries its own meaning — making them both the greatest challenge and the most rewarding milestone for Japanese learners.
漢字 refers specifically to the Chinese-derived characters integrated into Japanese writing over more than 1,500 years. A single kanji can represent a concept, a morpheme, or a standalone word. Most kanji have at least two readings: on-yomi (音読み), the Sino-Japanese pronunciation derived from ancient Chinese, and kun-yomi (訓読み), the native Japanese reading assigned to the same character. For example, 山 is read san (on-yomi) in 富士山 (Fujisan) and yama (kun-yomi) when used alone. The Japanese government designates 2,136 characters as jōyō kanji (常用漢字) — the standard set taught through compulsory education and used in official publications. Mastering these is considered the functional literacy benchmark for adult Japanese speakers.
Learners often conflate on-yomi and kun-yomi, but a reliable pattern exists: kanji used in compound words (熟語, jukugo) almost always take on-yomi, while standalone kanji or kanji followed by hiragana verb endings tend to use kun-yomi. For instance, 食 is shoku in 食事 (shokuji, meal) but ta in 食べる (taberu, to eat). When you encounter a new kanji, always note both readings separately rather than memorizing just one.
漢 (かん) refers to the Han dynasty (206 BCE–220 CE) of China, the civilization through which these characters reached Japan. 字 (じ) means “written character” or “letter,” derived from a pictograph of a child under a roof — evoking the idea of characters being nurtured and learned. Together, 漢字 literally means “characters of the Han (Chinese).” The term entered Japanese in the Nara period as scholars distinguished the imported script from Japan’s later-developed kana syllabaries.

Jōyō kanji wa nisen-hyaku-sanjū-roku-ji to sadame rarete imasu.

In Japanese compulsory education, children begin learning kanji in first grade with 80 characters and accumulate all 1,026 elementary-level kanji (教育漢字, kyōiku kanji) by sixth grade. This structured progression means that a kanji’s grade level is itself a cultural signal — writing a rare or high-grade kanji in casual conversation can come across as formal or even pretentious, while using an unexpected kun-yomi reading marks someone as well-read.
Kanji permeate Japanese professional and civic life in ways that go beyond simple literacy. Personal seals (印鑑, inkan) used to authorize contracts, bank transactions, and official documents are engraved with the owner’s name in kanji — making the visual form of one’s characters a matter of legal identity. In this context, the aesthetic choice of kanji style (standard, cursive, or seal script) carries weight that a purely phonetic system never could.
