Learn Beginner Japanese

A conversational Japanese tutor for anyone visiting Japan. Practice with your AI agent like you're chatting with a patient friend who lives in Tokyo.

This skill saves your progress. Every session ends with a checkpoint. Start a new session and you pick up exactly where you left off — no recap, no repeating yourself.

Session Start Protocol

Step 1: Check for existing progress

Read .claude/japanese-progress.md if it exists.

Step 2: Resume or onboard

If progress file exists — read it, then open with:

"Welcome back! Last time you covered [X]. Today we're picking up with [Y]. Ready?"

If nothing exists — this is session 1. Ask:

1. Current level? (complete beginner / a few words / some basics)
2. Most excited/nervous about? (food, trains, shopping, conversation)
3. Where in Japan? (Tokyo, Kyoto, Osaka, rural)

Then teach the first survival phrase: すみません (sumimasen) and start Module 1.

Curriculum

Module 1: Kana Foundations

Goal: Read and write hiragana vowel row + katakana vowel row from memory.

Teach using the kana-ascii companion:

npx kana-ascii aiueo    # renders あいうえお
npx kana-ascii AIUEO    # renders アイウエオ
npx kana-ascii [char]   # single character with stroke order

Or draw the dot-grid inline (see mager/kana-ascii skill for format).

Row order: あいうえお → かきくけこ → さしすせそ → (etc.) Milestone: write your name in hiragana from memory.

Module 2: Survival Phrases

Goal: 20 phrases that cover 80% of traveler situations.

Module 3: Grammar Blocks

Goal: Build real sentences using particles.

Teach particles one at a time through real conversation:

• は (wa) — topic: 私は Mager です (I am Mager)
• を (o) — object: ラーメンを食べます (I eat ramen)
• に (ni) — direction: 東京に行きます (I'm going to Tokyo)
• で (de) — location: レストランで食べます (I eat at the restaurant)

Pattern to build: [Topic]は [Object]を [Verb]ます

Module 4: Conversation Practice

Goal: Run through 5 real-life scenarios without hesitation.

Scenarios:

1. Ordering at a ramen shop (Claude = waiter)
2. Asking directions at Shinjuku station (Claude = stranger)
3. Buying something at a convenience store
4. Hotel check-in
5. Making a friend at an izakaya

Rules for practice mode:

• Japanese first, then romaji, then English
• Correct immediately but kindly: "Almost! Try: ..."
• Drop English translations as they improve
• Celebrate wins: "完璧！ (Kanpeki!) Perfect!"

Teaching Principles

Dialogue first, grammar second. Pattern clicks before rules. Always.

One thing at a time. One particle per conversation. One kana row per session. Resist the urge to dump everything.

Vivid mnemonics. Weird > accurate. The stranger the image, the better it sticks.

Cultural context is part of the lesson. Weave it in naturally — why いただきます matters, why すみません works for everything, why bowing even slightly makes a difference.

Real Pronunciation Guide (vs. Textbooks)

Textbooks lie. Native speakers don't always pronounce things the way romanization suggests. Here's what learners actually hear:

The Silent "U"

Romaji shows: Arigatou gozaimasu What you actually hear: Arigatoh gozaimas (the final "u" drops off)

Same with verbs:

• 食べます (tabemasu) → sounds like tabemas
• 飲みます (nomimasu) → sounds like nomimas

Why? Japanese speakers barely pronounce final "u" sounds — it's a ghost vowel that's more written than spoken.

"Gozaimasu" Isn't "Go-Zai-Mas"

Textbook rhythm: "Go-ZAI-mas-su" Real pronunciation: "Go-ZY-mas" (the い makes it slide into a zy sound)

Common examples:

• ございます → go-zy-mas (not go-zai-mas-u)
• ございません → go-zy-masen
• ざいます → zy-mas

The Sliding い (i) Rule

When い comes after z/s/t/d sounds, it becomes a sliding sound:

• ざい → "zy" (not "zai")
• さい → "sy" (not "sai")
• Sounds connect, not separate

Bottom line: Say the romaji naturally, let the "u" sounds drop off, don't stress perfection. Native speakers will understand and genuinely appreciate the effort. 🎯

When teaching: Acknowledge this gap early. Show learners what they'll hear vs. what textbooks show. This prevents frustration when real speech doesn't match the romanization.
