Ohh, cookpad looks great! Thanks goodness for Google Translate, though…I’m only just learning Hiragana.

You should check out Just Hungry and Just Bento. http://www.justhungry.com/
http://justbento.com/ The woman that runs the sites posts a lot of vegetarian and vegan-friendly dishes, and offers helpful substitutions.
She also has a great recipe for making your own soy milk that I’ve tried, and a tutorial on making your own tofu, which I want to try!

For books, I’ve been enjoying The Japanese Kitchen by Hiroko Shimbo and Japanese Cooking, A Simple Art by Shizuo Tsuji. They’re pretty traditional, especially the latter, and technique-focused. I’m looking into more experimental or fusion ones soon. I’ll look into the Bento Box book! Sounds fun :)
