About
Kaizen is a focused Japanese reader for classic literature. Read sentence by sentence with furigana, word lookup, sentence explanations, and optional audio playback for shadowing practice.
Built for learners who want to keep reading instead of managing flashcards, Kaizen keeps the interface quiet and puts the text first.
Features:
• Japanese classics prepared as clean reader editions
• Furigana controls for different reading levels
• Word and sentence reading modes
• Tap words for readings and meanings
• Sentence explanations for grammar and context
• Voice playback where audio is available
• Offline-friendly downloaded books
• A calm library built for slow, focused reading
Kaizen includes free public-domain readings and optional paid book editions. Some books may be available without voice first, with audio added later.
