Read full descriptionHide full description
For beginner students of the Japanese language, the writing system may seem unusual at first — but with this intuitive app, reading Japanese becomes easier than you think! Easy, interactive lessons will help you gradually memorize hiragana and katakana. You'll also learn around a thousand kanji, the characters taught to Japanese elementary school students from first through sixth grade — these are the most commonly used kanji in daily life. The app is designed for self-learners and is perfect for busy people looking to make the most of their time. Lessons are intuitive and can be repeated as often as needed. Once installed, the app runs exclusively on the Watch, with no iPhone required.
