Kanji Garden is a free kanji learning web app that's packed with customization features. Just fire up your browser, enter your email, and you're studying kanji. Procrastination, begone!
The interface is simple. Begin by choosing your ability level (beginner, intermediate, advanced) and/or handpicking the kanji you already know. Then start learning kanji, which you'll review later with spaced repetition.
The kanji study here is comprehensive, and you'll be prompted to learn your target kanji's meaning, on'yomi, kun'yomi, stroke order, and related characters. It's a lot to take in, which is why you'll want to make use of the "note" section (perfect for writing your own mnemonics).
The benefits of Kanji Garden will depend on how well you use its array of customization options and if you hold yourself accountable. Changing your reviews from the default multiple choice to forced input is a good start, and enabling notifications will help keep you on track. Pay attention to your progress on the stats page too—you'll make better study decisions that way. There's so much here that a disciplined student can take advantage of, and it's all free. So get to planting that kanji, and grow a beautiful garden in your brain!
