How to pursue graphic design studies in Japan or which sectors will have good demand in the future

Hello everyone

I am currently in Japan for a language program and will soon need to choose a vocational school or university. I have a background in graphic design with a diploma and work experience in the advertising/design sector in Bangladesh. My experience includes working on signboards, print jobs, and operating a CNC laser machine to cut acrylic sheets. I’m now at a crossroads about whether to pursue further studies in graphic design or explore other sectors. I’m looking for advice on: How I can pursue graphic design studies here in Japan. Are there any specific institutions or courses that would be ideal for someone like me? What sectors have high demand for the future, especially in the design and creative fields? Should I focus on another industry, and if so, which one?

Any advice or insights would be greatly appreciated. Thanks in advance!
