It sounds like there are multiple issues with your situation.

First of all, you don't have a college degree.

Secondly, your job options are limited because of that and even if you find something, many jobs you can find over the Internet requires you to be already in Japan. So you have a sponsor issue as well.

Thirdly, yes you could use your working holiday visa but there is an age limit and plus I'm not sure whether it covers spouses. Even if your wife has an Australian citizenship, you also have a daughter so that makes things even more complicated.

Finally, major universities in Japan offer less and less night classes and also for you to get in to a Japanese university itself is a big challenge. Because you have to be able to read and write in Japanese and then pass the entrance exam. You live in Taiwan so you should know how hard entrance exams are in Far East Asia.

So like chachava suggested, if you have to move out of Taiwan now, you probably should go back to Australia to complete your degree.
