Kanji are special characters used in the Japanese writing system.
Learning to use kanji involves understanding how they look and sound. People often use small symbols called furigana to show the phonetic sounds of a character. Some characters were even made in Japan by combining parts of other Chinese signs. In the past, writing was a very different task. Because paper was rare, people wrote on thin wooden strips called mokkan. 
History shows that kanji arrived in Japan from China a long time ago. They first appeared on items like coins, swords, and mirrors. One early example is a gold seal from 57 CE. 

There are many specific numbers to know about these characters. Nearly 3,000 kanji are used for common communication and names. Japanese children learn 1,026 characters in elementary school. This specific list is called the kyōiku kanji. After that, students learn more characters in junior high and high school. The full list for students, called the jōyō kanji, has 2,136 characters. The government has released different lists since the 1920s to help with education.
Kanji connects Japan to many other parts of Asia. Some Japanese-made words, called wasei-kango, have even been borrowed by other languages. For example, the Japanese word for telephone was used in Chinese, Korean, and Vietnamese. While some characters mean the same thing in China and Japan, others are unique. The character for "honest" is written the same way, but the sounds are different. This shows how one set of symbols can link many different cultures together.
Kanji are logographic Chinese characters used in the Japanese writing system. A logograph is a sign that represents a word or a specific idea.
Most kanji characters possess two distinct types of pronunciation. The first is called kun'yomi, which is based on native Japanese sounds. When kanji are read this way, they are often accompanied by furigana. Furigana are small phonetic characters written next to the kanji to show its sound. The second type is called on'yomi, which imitates the original Middle Chinese sound. This reading was used when the character was first borrowed from written Chinese.
The history of kanji in Japan began long before formal literacy was widespread. Archaeological sites from the Yayoi period have yielded inkstones and coins from the first century CE. A gold seal from 57 CE, given to a Wa emissary, is one of the earliest known imports. However, the Japanese people likely remained relatively illiterate until the fifth century CE. Legend says a scholar named Wani arrived from the Kingdom of Baekje during the reign of Emperor Ōjin. He brought with him the knowledge of Chinese characters and Confucianism. 
In ancient times, the physical medium of writing was quite different from modern paper. Because paper was extremely rare, people used mokkan, which are thin rectangular strips of wood. 
To manage the vast number of characters, the Japanese government has issued various official lists. In 1923, the government announced 1,962 characters for regular use. Following the Meiji Restoration, efforts were made to simplify characters to increase public literacy. This process created shinjitai, which are simplified versions of traditional characters. Today, students follow a structured path to learn these symbols. They first learn the kyōiku kanji, a list of 1,026 characters taught in elementary school. 
The complexity of kanji extends into the digital age through technical standards. The Japanese Industrial Standards, or JIS, define how characters are encoded for computers. The JIS X 0208 standard is a primary version used for information processing. There are also supplementary standards like JIS X 0212 and JIS X 0213. Some characters that are not included in these standard lists are called gaiji. These can be user-defined or specific to certain systems. Managing these characters is essential for consistent communication in modern technology.
Kanji also creates a unique connection between different Asian languages. Some characters, known as wasei-kango, are Japanese-made Chinese words. These are words created in Japan using Chinese components that were later borrowed by other nations. For example, the Japanese word for telephone was adopted into Chinese, Korean, and Vietnamese. While many characters share meanings across borders, some are unique to one language. The character for "honest" is written the same in both Japan and China, but the pronunciations differ. This demonstrates how kanji acts as a bridge for shared history and culture.
