Practice Japanese writing with Skritter, whether you have a strong grasp of written Japanese and want to remember the characters better or are a beginner who doesn’t know where to start. Skritter has existed for more than 10 years, and for a good reason: our learners are amazing! They help us with feedback, which allows us to create what we think is the best Japanese writing app out there! Japanese writing uses three different scripts; Hiragana, Katakana, and Kanji. Skritter offers all three and you can learn them through our “decks” (similar to a card deck) based on topics and difficulty. Deck examples: - Survival Japanese (for traveling in Japan) - Food and drinks (learn to understand the menus at your favorite Japanese restaurant with delicious sushi, ramen, and other dishes) - Cultural topics like Samurai Japanese - More advanced topics like foreign policy - And many more… First, you learn a character’s meaning, then practice drawing it and before you know it, you’ll want to learn thousands of characters, and words like these two happy users: “If I could only keep one app on my iPod, this would be it without a doubt. Skritter will change your life!” ― Wendy Werneth, UN Translator “Learning to write characters has never been so fun. From writing zero to 2000+ characters in six months!” ― Brian Jackson, Economist Have questions, problems, or feedback? We would love to hear from you.
