2. Numbers and Counting (20 words)
Numbers are the FOUNDATION of all communication. You'll need them to pay, order, ask for the time, etc.

| はち | Hachi | 8 |

10. Tips to Memorize All 100 Words
Congratulations! You now have a complete list of 100 essential Japanese words.
But how do you memorize them effectively?
Method 1: Spaced Repetition (SRS)
Use apps like:
- Anki (flashcards with spaced repetition algorithm)
- Memrise (memory games)
- Drops (10 min/day)
The principle: Review words just before you'd forget them. It's scientifically proven as the most effective method.
Method 2: Context Over Lists
NEVER learn words in isolation. Create sentences:
- ❌ "たべます = to eat"
- ✅ "わたしはラーメンをたべます。" (I eat ramen.)
The brain retains context much better.
Method 3: Speak Out Loud
Japanese learners repeat things out loud. Imitate the accent of a native speaker (YouTube, anime, dramas).
Method 4: Label Your Environment
Stick hiragana post-its on objects around your home:
- ドア (doa) on the door
- まど (mado) on the window
- つくえ (tsukue) on the desk
Method 5: Practice with Natives
Japan has a huge "language exchange" community. Use:
- HelloTalk (mobile app)
- Tandem (mobile app)
Or even better: live lessons with a native teacher on Targumi.
Realistic Schedule
| Period | Goal | Words/Day |
|---|---|---|
| Weeks 1-2 | Greetings + Numbers | 5 words/day |
| Weeks 3-4 | Time + Food | 5 words/day |
| Weeks 5-6 | Transport + Questions | 5 words/day |
| Weeks 7-8 | Adjectives + Verbs | 5 words/day |
| Weeks 9-10 | Everyday + Review | 5 words/day |
Result after 10 weeks: You've mastered 100 essential words and can hold a basic conversation in Japan!
Common Pronunciation Mistakes
Mistake #1: The Japanese "R"
The Japanese "r" (ら, り, る, れ, ろ) sounds neither like English "r" nor like "l". It's a quick flap of the tongue between the palate and the teeth.
Mistake #2: Vowel Length
In Japanese, vowel length changes meaning:
- おばさん (obasan) = Aunt
- おばあさん (obāsan) = Grandmother
Mistake #3: The "tsu" つ
The sound "tsu" doesn't exist in English as a standalone consonant. It's a quick "ts" sound like in "tsunami".
Conclusion: Your Foundation is Set!
With these 100 words, you now have solid foundations to communicate in Japanese.
But remember:
- Vocabulary alone ≠ language mastery
- You also need to work on grammar, conjugation, listening comprehension
Japanese is a beautiful but demanding language. With consistency and the right methods, anyone can master it.
Ready to Take It to the Next Level?
These 100 words are an excellent start. But to truly speak Japanese fluently, you need:
