I know it can sometimes be difficult to source good quality Japanese learning materials, so my friend and I have spent a bit of time making some cool Japanese learning bundles - http://nihongoup.com/japanese-bundle/ If you're trying to learn hiragana & katanaka, practice kanji, grammar, etc. then there's probably a pack for you. We've tried to keep the costs down as much as possible, so they're pretty affordable considering the quality.
I'd really love some feedback on them, if you have the time. What works? What would you like to see on your wall? Too cutesy? ^_^
