1.3 Writing Systems: Kanji

Kanji

Kanji (かんじ漢字) are characters originally borrowed from Chinese that Japanese uses mainly for nouns and the core meaning of verbs and adjectives. Unlike kana, where each character represents a sound, each kanji carries meaning — and can often be read in more than one way depending on the word and context.

Kanji are usually the part of Japanese that feels the most intimidating to learners at first. However, they are also what makes written Japanese much easier to read in the long run. Kanji reduce ambiguity, break long strings of kana into meaningful chunks, and help you recognize words faster once you are familiar with them.

Why Japanese uses kanji

Japanese has many words that sound the same but have different meanings. If everything were written only in kana, it would often be unclear which meaning is intended. Kanji solve this problem by visually encoding meaning.

For example:

• はし can mean “bridge” (はし橋), “chopsticks” (はし箸), or “edge” (はし端)

When written with kanji, the meaning becomes clear immediately.

Readings: onyomi and kunyomi

Most kanji have more than one reading. The two main types are:

• Onyomi: readings that originally came from Chinese
• Kunyomi: native Japanese readings

For example, the kanji やま山 can be read as:

• san (onyomi), as in ふじやま富士山
• yama (kunyomi), as in やま山

Which reading is used depends on the word, not on the kanji by itself. This is why kanji should always be learned in vocabulary, not in isolation.

Kanji components and radicals

Kanji are not random drawings. Most of them are built from smaller parts called components or radicals. These often give hints about meaning or pronunciation.

For example:

• き木 (tree)
• はやし林 (woods, two trees)
• もり森 (forest, three trees)

Learning to recognize these parts makes kanji much easier to remember and helps you guess the meaning of unfamiliar characters.

How many kanji are there?

There are tens of thousands of kanji in total, but you do not need all of them.

• Around 2,000 kanji are used in everyday Japanese
• About 2,136 are officially designated as Jōyō kanji
• Learning a few hundred already allows you to read simple texts

Kanji learning is a long-term process, but it is very manageable when done gradually.

How to learn kanji effectively

The most important points when learning kanji are:

• Learn kanji in words, not alone
• Focus on meaning and recognition first
• Do not try to memorize all readings at once
• Repeated exposure through reading is more important than writing practice

Being able to recognize kanji quickly will give you far more benefit than being able to write them from memory, especially in the beginning.

What comes next

From here, you will start encountering kanji naturally in vocabulary, grammar examples, and reading texts. You do not need to master kanji before moving on — you will build familiarity step by step as you continue learning Japanese.
