## Core Principles

### Copy-First Product Development (コピー起点)

A powerful approach: instead of "make product → write copy," reverse it to "write copy → design product."

**Example:** iPod's "1000曲をポケットに" (1000 songs in your pocket) - the copy came first, then the product was designed to deliver that promise.

**Process:**
1. Discover an insight through observation (not surveys)
2. Express the value in compelling words
3. Design the product to fulfill that promise

**Example: Pechat (ペチャット)**
- Product: Button-shaped speaker for stuffed animals
- Copy: "お気に入りのぬいぐるみが喋り出す" (Your favorite stuffed animal starts talking)
- Insight came from observing a shy daughter who opened up through stuffed animals

### Words as Lenses (言葉は眼鏡)

Words are like "glasses" that help us see the world differently:
- Naming unnamed concepts creates new value
- Changing words changes perception
- Find the "言われてみれば確かに" (now that you mention it...) insights

### Logic Over Inspiration (ロジック > センス)

Copywriting is **systematic technique**, not magical inspiration:
- Gifted people solve problems intuitively; everyone else needs systematic methods
- Like baseball: some hit naturally, but technique creates **reproducibility**
- "発想力" (creative inspiration) is vague; technique is concrete and learnable

### ワーディング is Everything

**Wording (ワーディング)** = the art of rephrasing

The core skill: How many ways can you say "おいしい" (delicious)?
- Not about marketing angles or positioning
- Pure linguistic rephrasing technique
- This IS copywriting

**Building your vocabulary:**
- Immerse yourself in quality Japanese text (not just copy)
- Copy-only study leads to imitation; broad reading leads to originality
- Read literature, essays, journalism - all good writing

### The Library in Your Head (頭の中の図書館)

Everyone knows roughly the same words, but **retrieval speed** differs:
- Like knowing English words but not being able to recall them when speaking
- Words "near the entrance" of your mental library come out easily
- Words "in the back" need training to access quickly

**Training:** Daily exposure + conscious practice moves words to the "front"

### Transcreation, Not Translation

Japanese copywriting requires **transcreation** (翻訳 + 創作) - adapting content to maintain intent, tone, and emotional impact rather than literal translation.

| Translation | Transcreation |
|-------------|---------------|
| Word-for-word conversion | Cultural adaptation |
| Preserves literal meaning | Preserves emotional impact |
| Often sounds unnatural | Feels native |
| Misses cultural context | Leverages cultural values |

### Cultural Values to Leverage

| Value | Japanese | Application |
|-------|----------|-------------|
| Trust | 信頼 (shinrai) | Build credibility before asking for action |
| Quality | 品質 (hinshitsu) | Emphasize craftsmanship over price |
| Harmony | 和 (wa) | Avoid aggressive or confrontational language |
| Humility | 謙虚 (kenkyo) | Understated claims, let quality speak |
| Detail | 細部 (saibu) | Provide comprehensive information |

### Avoid Western Patterns

| Western Style | Japanese Style |
|---------------|----------------|
| "Buy now!" | "ご検討ください" (Please consider) |
| "Best in class!" | "多くのお客様にご愛用いただいております" |
| Hyperbole/superlatives | Specific facts and numbers |
| Direct commands | Soft invitations |
| Fear of missing out | Fear of making mistakes |

---

## キャッチコピー (Catchphrases)

### Two Types

| Type | Purpose | Example |
|------|---------|---------|
| **Image Copy** (イメージコピー) | Brand awareness, not direct action | "そうだ京都、行こう" |
| **Response Copy** (レスポンスコピー) | Drive action, sales, conversion | "今だけ50%OFF" |

**Important:** For most business purposes, focus on **Response Copy** (レスポンスコピー):
- Has systematized, learnable techniques
- Directly drives revenue and action
- Image copy without brand budget often just annoys people

### Effective Patterns

| Pattern | Example |
|---------|---------|
| **Rhythm** (韻) | やめられない、とまらない |
| **Specific Numbers** | 満足度81.2% (not 80%) |
| **Questions** | 24時間働けますか？ |
| **"Wouldn't it be nice"** | あったらいいなをカタチにする |
| **Wordplay** | お、ねだん以上。ニトリ |
| **Self-deprecating** | 一目で義理とわかるチョコ |

See `reference/catchcopy-examples.md` for detailed analysis.

### Length Guidelines

- キャッチコピー: ~15 characters (scannable in 3 seconds)
- Tagline: 20-30 characters
- Headline: 30-40 characters

### Headlines Determine 50-75% of Success

**The headline is everything.** If the headline doesn't work, nothing else matters.

**Key principles:**
- Substantive long headlines beat empty short headlines
- Specific beats vague
- Longer copy beats shorter copy (when driving action)

**The Chain Rule:**
```
Title → exists to make them open the cover
Cover/OGP → exists to make them read line 1
Line 1 → exists to make them read line 2
Line 2 → exists to make them read line 3
...and so on
```

## Landing Page Copy

### Structure (起承転結)

```
1. 起 (Ki) - Hook/Catchcopy
   └─ Grab attention in 3 seconds

2. 承 (Sho) - Problem/Empathy
   └─ "こんなお悩みありませんか？"

3. 転 (Ten) - Solution/Benefits
   └─ Product introduction with proof

4. 結 (Ketsu) - CTA/Closing
   └─ Soft invitation to act
```

### First View (ファーストビュー)

Must include within visible area:
- Eye-catching visual
- Clear value proposition
- Primary CTA button

### CTA Best Practices

| Aggressive (Avoid) | Soft (Preferred) |
|--------------------|------------------|
| 今すぐ購入！ | まずは無料で試す |
| 申し込む | 詳しく見る |
| 買う | 資料をダウンロード |

**Power words to add:**
- 無料で (free)
- まずは (first/to start)
- たった○分で (in just X minutes)
- 簡単に (easily)
- 今だけ (limited time)

**CTA button examples:**
```
✅ 無料で資料をダウンロード
✅ まずは30日間お試し
✅ 3分で簡単お申し込み
✅ 詳しい情報を見る
```

### Trust Elements

Always include:
- Customer testimonials with real details (年代, 性別, 地域)
- Specific numbers (導入企業3,000社以上)
- Certifications/awards
- Media mentions (○○で紹介されました)
- Money-back guarantee (返金保証)

---

## Product Descriptions (商品説明)

### 6W2H Framework

| Element | Question | Example |
|---------|----------|---------|
| What | 何を | 商品名・種類 |
| Who | 誰が | 製造者・ブランド |
| Whom | 誰に | ターゲット顧客 |
| When | いつ | 使用タイミング・季節 |
| Where | どこで | 使用場所・原産地 |
| Why | なぜ | 購入理由・ベネフィット |
| How | どのように | 使用方法 |
| How much | いくら | 価格・コスパ |

### Structure

```
1. キャッチコピー (Hook)
   商品の最大の魅力を一言で

2. ボディコピー (Body)
   - 特徴・スペック
   - ベネフィット（体験価値）
   - 使用シーン
   - 口コミ・評価

3. クロージング (Close)
   - 限定特典
   - 保証情報
   - CTA
```

### Benefits vs Features (メリット vs ベネフィット)

**Critical distinction:** Features (メリット) describe the product. Benefits (ベネフィット) describe the customer's life.

| Feature (メリット) | Benefit (ベネフィット) |
|-------------------|----------------------|
| 500mlの大容量 | たっぷり使えて長持ち |
| 防水加工 | 雨の日も安心してお出かけ |
| 軽量設計（200g） | 長時間持っても疲れない |
| 副業で5万円稼げる | 諦めていたゴルフクラブが買える |

**The "Why, Why, Why" Technique:**

Keep asking "why does that matter?" to dig deeper:
```
Feature: 副業で5万円稼げます
↓ なぜそれが重要？
Benefit 1: 欲しかったものが買える
↓ なぜそれが重要？
Benefit 2: 家族とちょっといいレストランに行ける
↓ なぜそれが重要？
Benefit 3: 久しぶりに奥さんとデートできる
```

The deeper you go, the more emotionally compelling the copy becomes.

### Include Drawbacks (デメリットも書く)

Japanese consumers trust copy that acknowledges limitations:
```
※ 効果には個人差があります
※ 〇〇の方にはおすすめしません
※ 最初は〇〇に感じる方もいますが...
```

---

## Emotional Triggers (心理トリガー)

### Effective in Japan

| Trigger | Japanese | Application |
|---------|----------|-------------|
| Social proof | みんな使ってる | "累計○○万人が愛用" |
| Authority | 専門家推奨 | "○○医師監修" |
| Scarcity | 限定感 | "残りわずか" "期間限定" |
| Fear of regret | 後悔したくない | "今始めないと..." |
| Belonging | 仲間意識 | "○○な方に選ばれています" |
| Curiosity | 好奇心 | "その秘密とは？" |

### Less Effective in Japan

- Aggressive urgency ("買わないと損！")
- Extreme superlatives ("世界最高！")
- Fear tactics (too negative)
- Direct confrontation

---

## B2B / SaaS Copy

### Key Differences from B2C

| B2C | B2B |
|-----|-----|
| Emotional appeal first | Logic and ROI first |
| Individual decision | Consensus decision (稟議) |
| Quick conversion | Long sales cycle |
| Price sensitivity | Value/quality focus |

### B2B CTA Hierarchy

```
Primary:   資料ダウンロード (Download materials)
Secondary: 無料トライアル (Free trial)
Tertiary:  お問い合わせ (Contact us)
```

### Must-Have Content

- Detailed feature documentation
- Case studies (導入事例) with company names
- ROI calculations / cost savings
- Security certifications
- Support structure (日本語サポート)
- Comparison tables

### Formality Level

Use polite business language:
```
❌ 使ってみて！
✅ ぜひご活用ください

❌ すごく便利
✅ 業務効率化に貢献いたします
```

---

## Abbreviations & Slang

Match your demographic with appropriate shorthand:

| Full Form | Abbreviation | Demographic |
|-----------|--------------|-------------|
| スマートフォン | スマホ | General |
| コストパフォーマンス | コスパ | General |
| インスタグラム | インスタ | Younger |
| アプリケーション | アプリ | General |
| サブスクリプション | サブスク | Tech-savvy |
| タイムパフォーマンス | タイパ | Gen Z |

**Rule:** Use abbreviations only if your target audience uses them naturally.

---

## Practical Business Mindset

### "First to Say It Wins" (先に言ったもん勝ち)

Even if copy could apply to competitors, **saying it first** claims it:
- Generic benefits become yours if you articulate them first
- Don't overthink "unique angles" - clear articulation wins

### Good Copy = Client Satisfaction

In professional copywriting:
- Good copy is what the **client approves**
- Not what you think is clever
- Not what wins awards
- Technique exists to get chosen

### The Reality of "Angles" (切り口)

In real work, you rarely choose the angle:
- Client specifies target, key messages, tone
- Your job: **execute brilliantly within constraints**
- Don't romanticize "finding the perfect angle"

---

## Branding Through Copy

**Branding ≠ looking good.** Branding = making it easy for others to explain you.

**Test:** Can a stranger explain your product to another stranger?
- YouTube → "スマホやPCで動画が見れるサービス" ✅ Easy to explain

**Key insight:** Strength ≠ Brand. Converting strengths into **超説明しやすい形** = brand.

"ブランディングは言葉である" - Study copywriting to learn how brands are built.

---

## Common Mistakes

### Language Errors

1. **Machine translation** - Always use native speakers
2. **Wrong politeness level** - Match audience expectations
3. **Unnatural phrasing** - Sounds translated, not written
4. **Missing context** - Japanese needs more explanation

### Cultural Errors

1. **Too aggressive** - "Buy now!" feels pushy
2. **Too casual** - Damages brand trust in B2B
3. **Ignoring seasons** - Miss 季節感 opportunities
4. **Western humor** - Often doesn't translate
5. **Superlatives without proof** - "Best" needs evidence

### Format Errors

1. **Wrong date format** - Use 2024年1月15日
2. **Wrong currency** - ¥ before number, no decimals
3. **Missing 税込/税抜** - Always clarify tax inclusion
4. **Phone format** - 03-1234-5678 (with hyphens)

---

## Seasonal Campaigns (季節感)

| Season | Themes | Key Events |
|--------|--------|------------|
| 正月 (Jan) | New Year, fresh starts | 新年セール |
| 春 (Mar-Apr) | Cherry blossoms, new beginnings | 入学・卒業, 新生活 |
| 夏 (Jun-Aug) | Cool, refreshing, festivals | お中元, お盆 |
| 秋 (Sep-Nov) | Harvest, reading, appetite | ブラックフライデー |
| 冬 (Nov-Dec) | Year-end, Christmas, warmth | お歳暮, クリスマス |

**Don't miss:** バレンタイン (Feb 14), ホワイトデー (Mar 14), 母の日/父の日
