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:
- Discover an insight through observation (not surveys)
- Express the value in compelling words
- 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

| Whom | 誰に | ターゲット顧客 |
| When | いつ | 使用タイミング・季節 |

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

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.
