There seem to be a lot of people on here who have used WaniKani in the past (myself included).
I’m curious, for those who have studied Japanese, are you still studying it, or have you fully moved onto Chinese (+ potential other languages)?
Also!! Did you begin with Japanese and then move to Chinese or vice versa?
Maybe there could be a third option of “put on hold” but this is a great example of setting one’s intentions/facing reality: either you’re studying or not 
Where does given up on the Japanese (although might come back to it once my Chinese is good enough) vote on 
(Although I’m also a weird case of studying Chinese → Japanese for self study → then back to Chinese with self study…)
It’s a tough question. I do not study Japanese in a methodical way anymore like I do Chinese; i.e., I do not use Anki or WaniKani. But my Japanese is good enough that I feel I “study” when I speak with my friends, read the news, or watch media in Japanese.
This may be an interesting place to talk about language laddering, which is when you learn a third language using your second language. I personally don’t do this with Japanese → Chinese, but I could, and I think it would be particularly useful for 汉字.
Putting a language on hold is a very dicey game!! I’ve put a handful of languages on hold and I don’t think I’m ever taking them off the shelf again 
Oof tough question! Personally, if I were in that boat, knowing myself, I think the reality is that I would have moved on even if I’m not conscious of it 
Aha I think my questions are more related to the grassroots/very active learning route! I’d describe your learning as nearly-passive learning (though you are obviously learning and practicing when you’re speaking with friends and consuming media in Japanese).
I never knew language laddering had a name! I’ve definitely done this through Portuguese. I grew up speaking English and Serbian, and then learned Spanish to fluency throughout my childhood, and eventually used Spanish to bridge onto Portuguese.
Knowing Chinese helped so much with stepping into Vietnamese and Korean because of the all the sino-* words in those languages.
I’ve flirted with the idea of learning Japanese, and have thought about using language laddering through Chinese for learning it. At the very least, I can find Japanese textbooks here that use Chinese as the language of instruction.
Unfortunately, the selection of Chinese-Japanese dictionaries is extraordinarily slim, which surprised me given that the languages at the very least share part of the same script, and the countries neighbor each other. I did find some pretty good Chinese-Japanese Anki decks, but I really dislike Anki so I guess it does not matter too much.
I just wish there was something as good as Pleco for Japanese. I think if there was I would’ve started already. That is probably a good thing though, Chinese already took (and takes) up so much time, perhaps delaying learning Japanese is the most reasonable, responsible choice. 
Have you tried using jisho.org as a dictionary? It won’t do Chinese-Japanese, but when I was learning Japanese, I found it to be a REALLY good dictionary! If you use an iPhone, you can share the webpage to your home screen as a shortcut, and it’ll essentially act like an app lol
There is nothing as good as jisho.org. Neither Pleco nor MDBG are quite as slick yet comprehensive as jisho is. I would love to have an equivalent “zidian”.
