I went to a Japanese for beginners class in my last semester at university. Didn’t learn much there though, except maybe for reading Hiragana. Wish I had started earlier, but I never knew how much I was loving Japan before the end of my study. Now I’m working full time and therefore I can’t make it to any classes from university. Therefore, yes, I consider myself self-study.
Thanks to WaniKani (reading), Bunpro (grammar), SatoriReader (vocabulary), KaniWani (recalling), JapanesePod101 (listening) and these two Anki decks (writing) I feel like I’m doing good at the moment. The only thing I’m missing is speaking. I plan on adding that later via iTalki.
My wife, by the way, is still studying and attending Japanese classes. We’re kind of competing on who’ll be the one knowing more Japanese until our next holiday in Japan in spring sometime next year. Currently it looks like I’ll be the one who reads signs and restaurant menus as they are not learning any Kanji yet and she’ll be the one asking for directions and ordering since she’s got more speaking and grammar practice.
