Job seeking advice for someone with 1.7 years of job experience

In case someone has been through my previous, a quick recap. I graduated from a language school in 2024, and landed a job at a Japanese game company soon after. Unfortunately I was laid off at the end of March this year and have been job searching ever since, with no luck. My Work Visa ran out in September, but I managed to convert it to a Designated Activities Visa for 6 months. 3 months in, and that's where we are.

What I'd like to know is what I should work on to increase my odds of getting employed. My Japanese is N2 level and I'm working towards N1. English is my first language but I got a TOEIC S&W score of 400/400 just in case. And have 1 year and 7 months of combined professional experience at two separate game development studios. I've been looking into the game dev and IT sector in Tokyo, but with no luck, have been trying other fields as well. But I struggle to respond to a question like "Why did you decide to change industries" while applying for these jobs while being completely honest.

I would love to hear your advice on what I should work on, beyond my Japanese language skills.
