Lesson 8: First Kanji — 25 Characters You'll See Everywhere 🈯

Introduction: Your Gateway to Reading Japanese 📖

Congratulations on making it to Lesson 8! 🎉 You've mastered hiragana, learned essential phrases, and can now introduce yourself in Japanese. Now it's time to unlock the most fascinating part of the Japanese writing system: kanji (漢字).

Kanji are Chinese characters adopted into Japanese centuries ago. While there are thousands of kanji in existence, today you'll focus on 25 essential characters that appear everywhere in daily Japanese life. These aren't random selections—they're the most frequently used kanji you'll encounter on street signs, menus, calendars, and basic texts.

💡 Important mindset shift: In this lesson, we're focusing on recognition, not perfect writing. Being able to read these kanji is far more immediately useful than being able to write them from memory. Writing practice can come later!

Core Concept 1: What Makes Kanji Different? 🔤

Three Writing Systems Working Together

Japanese uses three scripts simultaneously:

┌─────────────────────────────────────┐
│  JAPANESE WRITING SYSTEMS           │
├─────────────────────────────────────┤
│ HIRAGANA (あいうえお)               │
│ → Grammar particles, verb endings   │
│                                     │
│ KATAKANA (アイウエオ)               │
│ → Foreign words, emphasis           │
│                                     │
│ KANJI (漢字)                        │
│ → Content words, meaning carriers   │
└─────────────────────────────────────┘

Kanji carry meaning and often represent entire words or word parts. A single kanji can express what might take several hiragana to write.

Example comparison:

• Hiragana: やま (yama) = mountain
• Kanji: 山 (yama) = mountain

Both say the same thing, but the kanji is more compact and easier to read quickly once you know it!

On'yomi vs. Kun'yomi: The Two-Reading System 🎭

Here's where kanji gets interesting (and challenging): most kanji have at least two different pronunciations.

Kun'yomi (訓読み) = Japanese reading

• The original Japanese word before kanji existed
• Usually used when the kanji stands alone
• Often written in hiragana in learning materials

On'yomi (音読み) = Chinese-derived reading

• The pronunciation borrowed from Chinese
• Usually used in compound words (two or more kanji together)
• Often written in katakana in learning materials

        KANJI: 山 (mountain)
            |
     ┌──────┴──────┐
     │             │
  KUN'YOMI     ON'YOMI
   やま          サン
   (yama)       (san)
     │             │
  山です        富士山
  (It's a     (Mt. Fuji:
  mountain)    Fuji-san)

💡 Memory tip: Think of kun'yomi as the "comfortable Japanese" reading and on'yomi as the "fancy compound" reading.

⚠️ Don't panic! You don't need to memorize all readings right away. Learn them as you encounter actual words.

Core Concept 2: Number Kanji (一~十) 🔢

Let's start with the most useful kanji: numbers 1 through 10. You already know how to say these numbers (ichi, ni, san...), now you'll recognize them in written form!

┌────┬────────┬──────────┬──────────┐
│ 漢字│ Kun    │ On       │ Meaning  │
├────┼────────┼──────────┼──────────┤
│ 一 │ ひと(つ)│ イチ/イツ │ one      │
│ 二 │ ふた(つ)│ ニ       │ two      │
│ 三 │ み(つ)  │ サン     │ three    │
│ 四 │ よ(つ)  │ シ       │ four     │
│ 五 │ いつ(つ)│ ゴ       │ five     │
│ 六 │ む(つ)  │ ロク     │ six      │
│ 七 │ なな(つ)│ シチ     │ seven    │
│ 八 │ や(つ)  │ ハチ     │ eight    │
│ 九 │ ここの(つ)│ キュウ/ク│ nine     │
│ 十 │ とお    │ ジュウ   │ ten      │
└────┴────────┴──────────┴──────────┘

🧠 Visual mnemonics:

• 一 = ONE horizontal line
• 二 = TWO horizontal lines
• 三 = THREE horizontal lines
• 十 = Looks like a PLUS sign, and 10 is 5+5!
• 八 = Looks like the number 8 flipped or opened up

🤔 Did you know? The kanji for three (三) is exactly what ancient people did when counting on their fingers—three horizontal marks!

Core Concept 3: Day Kanji (日月火水木金土) 📅

The seven kanji for days of the week are based on ancient astronomical and elemental concepts. Each day is associated with a celestial body or natural element:

┌────┬──────┬─────────┬──────────────┐
│ 漢字│ On   │ Meaning │ Day of Week  │
├────┼──────┼─────────┼──────────────┤
│ 日 │ ニチ  │ sun     │ 日曜日 (Sunday)  │
│ 月 │ ゲツ  │ moon    │ 月曜日 (Monday)  │
│ 火 │ カ    │ fire    │ 火曜日 (Tuesday) │
│ 水 │ スイ  │ water   │ 水曜日 (Wednesday)│
│ 木 │ モク  │ tree    │ 木曜日 (Thursday)│
│ 金 │ キン  │ gold    │ 金曜日 (Friday)  │
│ 土 │ ド    │ earth   │ 土曜日 (Saturday)│
└────┴──────┴─────────┴──────────────┘

🧠 Visual mnemonics:

• 日 = Picture of the SUN (circle with line through it)
• 月 = Crescent MOON shape
• 火 = Person with arms and legs spread—looks like FIRE
• 水 = Flowing WATER streams
• 木 = A TREE with branches and roots
• 金 = A treasure chest full of GOLD/METAL
• 土 = Layers of EARTH/SOIL

💡 Usage tip: Days of the week always end with 曜日 (ようび, youbi), which means "day of the week." So 月曜日 = げつようび = Monday.

Core Concept 4: Essential Everyday Kanji 🏔️

Now let's learn eight more kanji that appear constantly in daily Japanese:

People and Size

┌────┬─────────┬──────────┬─────────────────┐
│ 漢字│ Kun     │ On       │ Meaning         │
├────┼─────────┼──────────┼─────────────────┤
│ 人 │ ひと     │ ジン/ニン │ person, people  │
│ 大 │ おお(きい)│ ダイ/タイ │ big, large      │
│ 小 │ ちい(さい)│ ショウ    │ small, little   │
└────┴─────────┴──────────┴─────────────────┘

🧠 Visual mnemonics:

• 人 = Person standing with legs apart
• 大 = Person spreading arms wide (making themselves BIG)
• 小 = Three small dots (SMALL things)

Nature Kanji

┌────┬─────────┬──────────┬─────────────────┐
│ 漢字│ Kun     │ On       │ Meaning         │
├────┼─────────┼──────────┼─────────────────┤
│ 山 │ やま     │ サン     │ mountain        │
│ 川 │ かわ     │ セン     │ river           │
│ 口 │ くち     │ コウ     │ mouth, opening  │
│ 目 │ め       │ モク     │ eye             │
└────┴─────────┴──────────┴─────────────────┘

🧠 Visual mnemonics:

• 山 = Three MOUNTAIN peaks side by side
• 川 = Flowing RIVER with parallel currents
• 口 = An open MOUTH (square opening)
• 目 = An EYE turned sideways

🤔 Did you know? Many Japanese place names use these kanji! 富士山 (ふじさん, Fujisan) = Mt. Fuji, 川崎 (かわさき, Kawasaki) = riverside cape.

Core Concept 5: Introduction to Radicals 部首 (ぶしゅ) 🧩

Radicals are the building blocks of kanji. They're components that:

1. Give hints about meaning
2. Help you organize kanji in dictionaries
3. Make memorizing easier

Many of the kanji you've learned today are themselves radicals!

  RADICAL EXAMPLES
  
  水 (water radical) appears in:
  ├─ 泳 (swim)
  ├─ 海 (ocean)
  └─ 池 (pond)
  
  人 (person radical) appears in:
  ├─ 休 (rest: person by tree)
  ├─ 体 (body)
  └─ 何 (what)
  
  口 (mouth radical) appears in:
  ├─ 名 (name: say in evening)
  ├─ 食 (eat)
  └─ 味 (taste)

💡 Learning strategy: When you see a kanji with 水, think "probably related to water." With 人, think "probably related to people." This makes kanji feel less random!

⚠️ Common mistake: Don't confuse radicals with the complete kanji. 木 can mean "tree" on its own, but it also appears as a component in 森 (もり, forest = three trees!).

Example 1: Reading a Calendar 📆

Scenario: You're looking at a Japanese calendar to plan your week.

┌──────────────────────────────┐
│   二月 (にがつ = February)   │
├────┬────┬────┬────┬────┬────┤
│ 日 │ 月 │ 火 │ 水 │ 木 │ 金 │
│    │  1 │  2 │  3 │  4 │  5 │
│  6 │  7 │  8 │  9 │ 10 │ 11 │
│ 12 │ 13 │ 14 │ 15 │ 16 │ 17 │
└────┴────┴────┴────┴────┴────┘

Breaking it down:

• 二月 (にがつ) = Second month = February
  • 二 (に) = two
  • 月 (がつ) = month
• Column headers are days: 日 (Sunday), 月 (Monday), 火 (Tuesday), etc.
• You can now recognize any Japanese calendar!

🔧 Try this: Look at February 10th (十日). This would be read as じゅうにち (juunichi) = 10th day.

Example 2: Counting Things with Kanji 🧮

Scenario: You're at a restaurant and see prices written in kanji.

メニュー (Menu)
─────────────────
🍜 ラーメン    八百円
   (Ramen)    800 yen
   
🍵 お茶      二百円
   (Tea)     200 yen
   
🍱 定食      千円
   (Set meal) 1000 yen

Breaking it down:

• 八百円 = はっぴゃくえん = 800 yen
  • 八 (はち/はっ) = eight
  • 百 (ひゃく) = hundred (new kanji, but good to know!)
  • 円 (えん) = yen
• 二百円 = にひゃくえん = 200 yen
• 千円 = せんえん = 1000 yen

💡 Real-world tip: Prices in Japan often use kanji for round numbers. Being able to recognize 百 (hundred) and 千 (thousand) is incredibly useful!

Example 3: Reading Signs and Place Names 🗾

Scenario: You're navigating Tokyo and see these signs:

┌─────────────┐     ┌─────────────┐
│  出口 EXIT  │     │  入口 ENTER │
└─────────────┘     └─────────────┘
   (deguchi)           (iriguchi)

Breaking it down:

• 出口 = exit
  • 出 = to go out (new kanji)
  • 口 = mouth/opening
  • Together: "exit opening"
• 入口 = entrance
  • 入 = to enter (new kanji)
  • 口 = mouth/opening
  • Together: "entrance opening"

Notice how 口 (mouth/opening) is used in both? That's the radical giving you a hint about meaning!

🌍 Place name example: 山口 (やまぐち, Yamaguchi)

• 山 (やま) = mountain
• 口 (くち/ぐち) = opening
• Together: "mountain opening" (a city name)

Example 4: Understanding Compound Words 🔗

Scenario: You see these words using kanji you've learned:

SINGLE KANJI → COMPOUND WORDS

人 (person)  ┬→ 日本人 (Japanese person)
             │   にほんじん
             │
             ├→ 二人 (two people)
             │   ふたり
             │
             └→ 大人 (adult)
                 おとな

山 (mountain)┬→ 火山 (volcano)
             │   かざん (fire mountain!)
             │
             └→ 山川 (mountains and rivers)
                 さんせん

💡 Pattern recognition: Notice how on'yomi is usually used in compounds:

• 日本人 uses じん (on'yomi)
• But 二人 uses ふたり (kun'yomi because it's a native Japanese counting word)

This is why we said don't memorize all readings at once—learn them through actual words!

Common Mistakes to Avoid ⚠️

Mistake 1: Confusing Similar-Looking Kanji

❌ COMMONLY CONFUSED

一 (one)    vs  二 (two)
Tip: Count the lines!

人 (person) vs  入 (enter)
Tip: 人 legs spread apart, 入 legs together

十 (ten)    vs  土 (earth)
Tip: 十 is taller, 土 is wider

Mistake 2: Using Wrong Readings

❌ Wrong: 山 in 富士山 read as "やま" ✅ Correct: 山 in 富士山 read as "さん" (on'yomi for names)

💡 Rule of thumb: If a kanji is alone or with hiragana, probably kun'yomi. If with other kanji, probably on'yomi.

Mistake 3: Forgetting Kanji Have Multiple Meanings

❌ Thinking 日 only means "sun" ✅ Knowing 日 means: sun, day, Japan (in compounds)

Examples:

• 日曜日 = Sunday (sun day)
• 今日 = today (this day)
• 日本 = Japan (sun origin)

Mistake 4: Trying to Write Kanji Perfectly from Day One

❌ Spending hours practicing stroke order for all 25 kanji ✅ Focusing on recognition first, writing later

⚠️ Reality check: Native Japanese speakers can read thousands of kanji but might struggle to write some from memory. Recognition is the priority!

Key Takeaways 🎯

1. Kanji carry meaning and are more compact than hiragana for content words
2. Two readings exist: kun'yomi (Japanese) and on'yomi (Chinese-derived)
3. Number kanji (一~十) appear everywhere and follow visual logic
4. Day kanji (日月火水木金土) are based on celestial bodies and elements
5. Radicals are components that give hints about meaning
6. Recognition before production: Learn to read before you learn to write
7. Context determines reading: Compounds usually use on'yomi
8. Visual mnemonics help: 山 looks like mountains, 川 looks like a river
