What Is Kanji? A Beginner's Guide

The quick answer

Kanji are characters that carry meaning in written Japanese. They do not work like the separate letters in an English word. A single character such as 山 can point to the idea “mountain” and take the reading やま in the word 山(やま).

Japanese normally uses kanji together with hiragana and katakana. You are not replacing kana when you begin kanji. You are adding another layer to a writing system you already know.

Three scripts can share one sentence

Hiragana often writes grammar and word endings. Katakana commonly writes loanwords and some names. Kanji carry the roots of many everyday words.

Consider 学校(がっこう), “school.” Both characters contribute to the word. Now look at 食べます(たべます), “eat” or “will eat” in polite speech. The character 食 carries the main idea of eating, and べます is written in hiragana.

The kana after a kanji are called okurigana when they show part of a word’s reading and grammatical form. You do not need to memorize that term immediately, but you will see the pattern often.

Why one character can sound different

A kanji can have more than one reading because Japanese adapted Chinese characters over a long period and connected them with both borrowed sound-based readings and native Japanese words.

For example:

• 山(やま) means “mountain” as a word by itself.
• 富士山(ふじさん) is “Mount Fuji,” where 山 is read さん.
• 水(みず) is “water.”
• 水曜日(すいようび) is “Wednesday,” where 水 is read すい.

This does not mean you should recite every possible reading before learning any words. It means the word itself tells you which reading is useful.

Learn a meaning, then meet it in words

A productive beginner routine has three parts:

1. Notice the kanji and its central beginner meaning.
2. Learn one or two useful words that contain it.
3. Read those words in a short phrase or sentence.

Take 学, “study” or “learning”:

• 学生(がくせい) — student
• 学校(がっこう) — school
• 学ぶ(まなぶ) — to learn

The first two words use ガク. The verb uses まな before its hiragana ending. The words make those readings concrete.

Where kanji came from

Kanji were historically adopted from Chinese writing. Japanese speakers then developed conventions for using the characters with Japanese words and grammar. That history helps explain why characters may have several readings, but you do not need an academic history course before you start reading.

A memory hook is different from a historical origin. A memory hook is a modern association that helps you remember a shape. An origin note should describe the character’s documented development. Japan Alphabet keeps those labels separate.

What to study first

Become reasonably comfortable with basic kana, then add kanji gradually while you continue learning vocabulary and simple grammar. You do not have to finish every detail of kana before seeing your first kanji.

Start with a small connected set—such as the number kanji—and return to it in mixed review. Recognition becomes more reliable when you meet the same character in useful words instead of only in a chart.
