Have you heard of Yomichan? I love this plugin. It’s a little Japanese hover-dictionary for your browser and will translate all sorts of words for you, including kana-only words. You can also connect it to Anki so that whatever you look up can be thrown into your own custom deck.
I thought Kitsun is in open beta now, so if you’re waiting for a while on your invite you might want to pop into this thread and talk to the developer.
Besides that, there’s also quite a few Japanese vocab courses on Memrise.
