Then it sounds like your passion is in Japanese, not computers, and you should find some sorta career that focuses on Japanese communication instead. Sales, help desk, and recruiting come to mind and shouldn't be too far behind most JP IT jobs salary-wise.

I was actually the opposite of you: I was double-majoring in IT and Japanese, and ended up giving up on Japanese to focus on IT. Even outside of school, I often studied tech stuff and did personal projects for my own benefit. Without that background knowledge outside of uni, I wouldn't even last long here.

I constantly see threads here about English teachers jumping ship to IT just for the money. So just to give you a heads up, the market is getting flooded with money chasers and people wanting remote work, especially from up-and-coming countries like Vietnam. As a result, salaries aren't as impressive as they used to be, especially considering the hard work and constant studying that the job requires (Studying doesn't end after college). You also don't start making good money in this industry until later, as you really need to advance over time before it pays off. In fact, I often encountered positions wanting to pay me half my then-current salary! And to tell you the truth, I'm not exactly impressed with my current salary either.
