Here are the eighty kanji needed for Level 4 of the JLPT, presented a few at a time for easy perusal, contemplation, assimilation and retention.
This set of pages will be useful for those of you who would appreciate a bit more guidance through the earlier stages. I originally envisaged the site as a useful way to practise kanji rather than learn them, but hopefully it will prove suitable for both. I recommend you have a pen and piece of paper ready to complement the experience. Kanji are often much easier to learn if you write them yourself - something I can't help you with - yet.
