Focus on Benefits, Not Features
The original copy emphasizes technical features. Japanese users often respond better to clear outcomes than feature lists. Instead of highlighting that the app is 'AI-powered', we focused on saving time.
Japanese User Tip & Insight
Japanese App Store users typically look for practical value first. Copy that answers 'How does this help me?' feels much more trustworthy than feature-heavy descriptions.
