In my ever-ongoing search for a solid hiragana chart, I came across these gems, floating around the internet. I’m not sure where I first saw them, but I tracked the original creators to deviant art- na-insoo & starshock12. They’ve done a fantastic job with these posters (which you can order through deviant art.)

So what makes these posters so great? It’s the fact that each kana (one poster for hiragana & one for katakana) features an anime or video game character that use it in their name.

Apparently the artists got some flak for mixing the English & Japanese names, but I think it’s a great thing.
