Untangling the Shared Origins and Evolutions of Chinese Hanzi, Japanese Kanji, and Korean Writing Systems
Chinese characters, known in Chinese as hanzi, have a history dating back over 3000 years to oracle bone inscriptions of the Shang Dynasty. As one of the world’s oldest continuously used writing systems, hanzi developed into a sophisticated logographic system with thousands of unique characters.
When Chinese culture spread to neighboring regions like Japan and Korea beginning around the 5th century CE, written Chinese and knowledge of hanzi went with it. But the Chinese script would be adapted within each language and evolve in different ways.
In Japan, hanzi became known as kanji. Kanji uses traditional Chinese characters and has many of the same mechanics as hanzi. Like Chinese, Japanese kanji are logographic – each character represents a word or concept rather than a specific sound.
However, pronounced differently than Chinese and adapted to fit the Japanese language, individual kanji can have multiple possible readings. While a Chinese hanzi has one main reading, a single kanji can be read different ways in Japanese depending on context.
Additionally, Japanese writing includes syllabaries called hiragana and katakana alongside kanji. Schoolchildren in Japan have to memorize thousands of distinct kanji just for common use, as well as learn the syllabary scripts.
In Korea, Chinese characters were originally known as hanja and served as the basis for the Korean written language for centuries. Hanja also share similarities with Chinese hanzi in that they represent full words or ideas.
However, in the 15th century King Sejong the Great developed a revolutionary new alphabetic system known as hangul. Designed to increase Korean literacy, hangul letters represent sounds rather than concepts. While Chinese characters are still sometimes used in South Korea, primarily for stylistic purposes, hangul became the primary everyday writing system due to its efficiency.
Differences between Chinese, Japanese, and Korean characters
While Chinese, Japanese, and Korean characters all originated from Chinese script, several key traits distinguish them:
Stroke Order – Kanji and hanja generally follow the same stroke order for writing characters as Chinese hanzi, starting in the upper left. Though hangul as an alphabet has no stroke order rules.
Character Simplification – After the formation of the People’s Republic of China, the government initiated a major simplification of many hanzi. Kanji and hanja maintain the traditional pre-simplification forms.
Regional Styles – Chinese hanzi evolved unique calligraphic styles by region historically. Kanji and hanja kept a single standard style similar to kaishu regular script.
Native Characters – Kanji and hangul added modified or invented characters to represent native Japanese and Korean words and grammar patterns lacking in Chinese.
Pronunciation – Each system pronounces the characters according to the languages’ distinct phonology, rather than Chinese readings.
Vocabulary Usage – Characters may take on different meanings or levels of frequency when absorbed into Japanese and Korean.
To the untrained eye, Chinese, Japanese, and old Korean texts may appear indistinguishable as all seemingly using Chinese hanzi. In modern Korean that relies primarily on hangul, this is no longer an issue. But for Japanese kanji versus Chinese hanzi, only those knowledgeable in the languages can readily tell them apart based on grammar conventions and vocabulary choices that reveal themselves as uniquely Chinese or Japanese in context.
The intertwined histories of the writing systems reveal the shared foundations of Chinese script influencing the entire region. But gradual evolution rendered hanzi, kanji, and hanja distinct solutions for representing their own languages in writing. And hangul stands uniquely apart as a deliberately engineered alphabetic system.
Though they draw from the same ancient source material, mastery of any one of these writing forms does not automatically enable comprehension of the others. One must immerse in each language’s intricacies to read Chinese, Japanese, or old Korean works fluently, as only deep understanding clarifies their common background and reveals the nuanced differences that make each writing culture unique.
