The 214 traditional kanji radicals and their meanings

If you’ve ever stared at a kanji and thought I have no idea what this means and I never will — this article is going to change everything.

The secret that most beginners miss isn’t vocabulary lists or grammar charts. It’s radicals.

214 Japanese Kanji Radicals (部首) with Meanings, Stroke Count & Examples

The 214 Japanese kanji radicals (部首, bushu) are the building blocks that almost every kanji is made from. Learn them and you’ll start to see inside characters — recognizing familiar pieces, guessing meanings, and memorizing new kanji at three to five times the speed.

In this guide, Japanese tutor Fumito Emi at reading-japanese.com breaks down all 214 Kangxi radicals with their meanings, stroke counts, and example kanji — you can use with Anki, as a printable reference, or as a study companion at your desk.

Before we dive in: if you haven’t yet learned hiragana and katakana, do that first. The hiragana chart and katakana chart on this site and will take about two weeks combined. Radicals become dramatically easier once you have the kana foundation.

What Are the 214 Kanji Radicals?

A radical (部首, bushu) is the key component used to classify and index a kanji in a dictionary.

Every single kanji — all 2,136 Joyo kanji, all 50,000+ characters in existence — belongs to one of these 214 groups. When you look up a kanji you don’t know in a traditional dictionary, you find it by identifying its radical, looking that radical up in the index, then counting the remaining strokes.

The 214 Kangxi radicals were established in China’s Kangxi Dictionary of 1716 (康熙字典, Kōki Jiten), one of the most comprehensive Chinese dictionaries ever compiled. Despite being over 300 years old, this classification system is still used in modern Japanese and Chinese dictionaries today.

In Japanese, radicals are called 部首 (bushu) — 部 means “section” and 首 means “head” or “beginning.” Together: the “section head” of a character grouping.

Why Learning Radicals Changes Everything

Let me be direct about this, because most Japanese study materials bury it.

Radicals are not optional. They are the difference between treating kanji as meaningless shapes to memorize and treating kanji as a logical, decodable system.

Here’s what changes when you know your radicals:

You Can Guess the Meaning of Unfamiliar Kanji

Look at these characters:

• 海 (sea)
• 河 (river)
• 泳 (swim)
• 汚 (dirty)
• 波 (wave)
• 湖 (lake)

What do they all share? The 水 (water) radical, which appears as 氵 on the left side. If you know that radical, you know every one of these characters has something to do with water — before you’ve ever studied them.

That’s not magic. That’s the system working exactly as intended.

You Memorize Kanji Three to Five Times Faster

Research in language acquisition consistently shows that information organized into meaningful chunks is retained far better than isolated facts. Radicals are the chunking mechanism for kanji.

When you learn 休 (rest), don’t memorize it as an abstract shape. Learn that it’s 人 (person) + 木 (tree) — a person leaning against a tree, resting. That image takes ten seconds to understand and doesn’t fade.

You Can Look Up Kanji Without a Reading

When you encounter a kanji you’ve never seen — in a menu, on a sign, in a manga — and you have no idea how to read it, radicals are how you find it. Identify the radical, count the strokes, check the index.

Before smartphone OCR existed, this was the only way. And it’s still faster than drawing in most situations.

Patterns Emerge Across Hundreds of Characters

Once you know that 心 (heart/mind) appears as 忄 in characters related to feelings and thought, you’ll notice it everywhere:

• 情 (emotion) — 忄 + more strokes
• 悲 (sad) — 忄+ more strokes
• 怒 (angry) — 忄 + more strokes
• 慢 (arrogant) — 忄 + more strokes

Knowing one radical gives you a hook for dozens of kanji simultaneously.

How the 214 Radicals Are Organized

The Kangxi system organizes radicals by stroke count — from 1 stroke to 17 strokes. Within each stroke group, radicals are numbered from 1 to 214.

Here’s the distribution by stroke count:

Complete List: All 214 Kangxi Radicals

1–2 Stroke Radicals (Radicals 1–30)

These are the most abstract radicals — basic strokes and shapes that appear inside more complex characters. Many of them don’t look like recognizable objects, but they’re essential because they appear constantly.

3–4 Stroke Radicals (Radicals 31–99)

This is the richest group — it contains some of the most important radicals in all of Japanese. 心 (heart), 手 (hand), 日 (sun), 木 (tree), 水 (water), 火 (fire) are all here. Master these and you’ve unlocked the core of the kanji system.

5–6 Stroke Radicals (Radicals 100–155)

7–8 Stroke Radicals (Radicals 156–184)

9–10 Stroke Radicals (Radicals 185–204)

11–17 Stroke Radicals (Radicals 205–214)

These are the rarest and most complex radicals. You’ll encounter them less frequently, but they’re important for reading classical texts, literary kanji, and JLPT N1 vocabulary.

The 30 Most Important Radicals to Learn First

If you’re starting from zero, don’t try to memorize all 214 at once. Learn these 30 first — they appear in an enormous proportion of all common kanji.

Radical Variants — The Shape-Shifters

One of the trickiest things about radicals is that many of them change shape when used as a component inside a character. Beginners often fail to recognize these variants, which breaks the pattern-recognition that makes radicals so powerful.

Here are the most important shape changes to memorize:

Important note: 阜 and 邑 both become 阝 — but they appear on opposite sides of the character. 阜 goes on the left (as in 院, 陸), and 邑 goes on the right (as in 部, 郡). This trips up learners constantly.

How to Use Radicals to Guess Kanji Meaning

Here is the most practical skill you can develop as a kanji learner. When you see an unfamiliar kanji, ask:

“What radical do I recognize? What does that radical mean? What might this character be about?”

Examples of Radical-Based Guessing

You see: 泳

• You recognize: 氵 (water) on the left
• You guess: something to do with water
• Actual meaning: 泳 = to swim ✓

You see: 晴

• You recognize: 日 (sun) on the left
• You guess: something to do with the sun or weather
• Actual meaning: 晴 = clear, sunny ✓

You see: 悲

• You recognize: 心 (heart) at the bottom
• You guess: an emotion or feeling
• Actual meaning: 悲 = sad, sorrowful ✓

You see: 鳴

• You recognize: 鳥 (bird) on the right, 口 (mouth) on the left
• You guess: a bird making a sound?
• Actual meaning: 鳴 = to chirp, to ring, to sound ✓

You see: 森

• You recognize: three 木 (tree)
• You guess: something with many trees
• Actual meaning: 森 = forest ✓ (林 with two trees = grove)

This method isn’t perfect — some kanji radicals indicate sound rather than meaning, and some are irregular. But as a first-pass system, it works remarkably well and makes each new kanji an interesting puzzle rather than a wall of meaningless shapes.

How to Build Your Radical Anki Deck

The most efficient way to learn all 214 radicals is with a spaced repetition system. Here’s the exact setup for your radical Anki deck:

Card Format

Front:

• The radical (large: 人)
• Its variant form if it has one (亻)

Back:

• Number in the Kangxi system (9)
• Stroke count (2)
• Meaning (Person)
• Example kanji using this radical (仕, 住, 何, 信, 使)
• Brief mnemonic note (A person walking in profile)

Study Order

Don’t study radicals in numerical order (1, 2, 3…). Study them in frequency order — most useful first. Use this priority:

1. Start with the 30 highest-priority radicals in the table above
2. Next, add the remaining 2–4 stroke radicals
3. Then 5–6 stroke radicals
4. Then 7+ stroke radicals

Daily Card Target

• New cards per day: 5–10 radicals
• At 5/day: Complete all 214 in 6–7 weeks
• At 10/day: Complete in 3 weeks

Combine with JLPT N5 vocabulary study — see our JLPT N5 vocabulary guide — so you’re always seeing radicals in the context of real words.

FAQ

❓ What are the 214 radicals called in Japanese?

They are called 部首 (bushu). 部 (bu) means “section” or “group,” and 首 (shu/kubi) means “head” or “beginning.” Together: the “section head” of a kanji group. You might also hear 偏旁 (henbo) used to describe components more broadly.

❓ Do all Japanese kanji use the Kangxi radical system?

Yes — the 214 Kangxi radicals are the standard system for indexing all kanji in Japanese dictionaries. Some modern digital dictionaries allow searching by reading or stroke, but the radical system remains the universal reference standard.

❓ Are radicals the same thing as “parts” or “components” of a kanji?

Not exactly. A kanji can have multiple visible components, but officially it has only one radical — the one used to index it in the dictionary. For example, 明 (bright) has both 日 (sun) and 月 (moon), but its dictionary radical is 日. However, for learning and memorization, it’s useful to study all components, not just the official radical.

❓ How do I know which component is the radical?

This requires some practice. Generally, the radical is the component that relates most directly to the meaning. In water-related characters (海, 泳, 河), 氵 is always the radical. In characters with 木 (tree), the tree is usually the radical. Over time, you’ll develop an intuition. Reference books and apps like Jisho.org display the official radical for every kanji.

❓ Are there more than 214 radicals?

The Kangxi system has 214, but some sources list different numbers. The Nelson Japanese-English Character Dictionary uses 186, and some simplified systems use as few as 79. For most Japanese learners, the 214 Kangxi system is the most useful because it aligns with standard dictionaries and the JLPT.

❓ Do I need to memorize all 214 radicals before studying kanji?

No — and that would actually slow you down. The best approach is to learn the most common ~50 radicals alongside your kanji study. When you encounter an unfamiliar radical, look it up in this. Over months of study, all 214 will become familiar naturally.

❓ How do radicals help with JLPT preparation?

Radicals help you guess the meaning of kanji you haven’t specifically studied — which is extremely useful in the JLPT’s reading comprehension sections. When you recognize that an unfamiliar N2 kanji has the 病 (illness) radical, you can infer it’s medically related and read the surrounding context more accurately. Our JLPT N5 vocabulary list is organized to complement your radical study.

❓ What is the best book for learning kanji radicals?

Remembering the Kanji by James Heisig is the classic Western resource for radical-based kanji memorization. For a more Japanese-school approach, Basic Kanji Book by Kano et al. is excellent. Combine either book with the resources at reading-japanese.com and an Anki deck for best results.

🎯 Your Radical Journey Starts with One Stroke

You’ve just read through all 214 Kangxi radicals. Most learners never do this — they try to memorize kanji one by one, without the system, and burn out somewhere around the four-hundredth character.

You now have the system.

Every kanji you learn from here is a combination of pieces you already know. 海 isn’t a random shape — it’s water (氵) plus a mother (母) plus something else, which together mean “sea.” Once you see it, you can’t unsee it.

Start with the 30 highest-priority radicals. Build your Anki deck. And come back to this reference whenever you encounter a radical you don’t recognize.

The kanji system is not your enemy. It’s a 3,000-year-old visual language, and you’re learning to read it.
