I dread the day I’ll have to find out whether any of my self-taught Japanese will hold water in an actual conversation. Hah. Joking aside, I’ve made a lot of progress. I’ve covered the a-, k-, s-, t-, and n-series and by extension g, z, and d (of the hiragana).
I’ve been piecing together different resources to move things along. NYC’s Japan Society has YouTube videos on vocabulary, phrases, and grammar that I found useful. NHK WORLD's got some textbook-style worksheets and accompanying audio. And here's a demo version of the language learning software that got me started on learning the characters. I also printed out a bunch of worksheets a la Phonics to help me with the writing. EDIT: I forgot to include this very useful flashcard phone app for memorizing characters.
The day I can read a Japanese nursery rhyme will be a great day indeed.
