Learn Hiragana the Easy Way Kana helps you learn Japanese hiragana step by step. You start with the basic sounds and work your way toward reading simple words and short sentences. Everything unlocks naturally as you learn, so you always know what to practice next. How Learning Works You begin with the five main vowel sounds. Each character becomes marked as learned after you get it right three times in a row. Once you finish a small group of characters, the next group becomes available. The pace is steady and manageable. Practice Words After you unlock enough characters, you can start practicing real words. Each word only appears once you already know the characters inside it, so you are never guessing. Words are grouped into small milestones that feel easy to reach. Build Sentences As you learn more words, you will unlock simple sentences. These start out very short and slowly grow in complexity. This helps you see how Japanese fits together in a natural way without overwhelming you. Track Your Progress You can check your progress anytime. The stats page shows your accuracy, how many characters you have learned, how many words you can read, and which milestones you have completed. Roadmap View The roadmap lays everything out visually, so you know exactly what is coming next. It shows how characters lead to words and how words lead to sentences. Key Features • Learn characters in small steps • Words unlock only when you are ready • Sentences appear naturally as your vocabulary grows • Clean and simple design with dark mode • No ads and no subscriptions • Works offline Perfect For • Beginners learning Japanese for the first time • Students wanting extra practice • Travelers wanting to read signs and menus • Anyone who wants a simple, straightforward approach Why It Works A long list of characters can feel intimidating. Hirgana breaks everything into short milestones, letting you build confidence without rushing. Because words and sentences only unlock once you know the basics, nothing ever feels out of reach. Start learning today. Take small steps, build real skills, and see steady progress.
