What sort of IT career could I switch to in Japan?
30y/o Computer Science graduate from the UK, worked remotely for a US company for three years (Audio/Video/Graphics Editor then Creative Lead) then moved to Japan. It's currently my fourth year as an ALT English teacher in the countryside. Passed JLPT N1 last year and have good conversational Japanese. I have been doing web developement since last year using AI agents (VS code, Antigravity, Claude Code, Codex, Git, OpenCode, OpenRouter, Ollama, Copilot, Cursor, Windsurf, etc.) to make web apps for myself and other teachers. I ended up making a full SaaS product that currently has 78 users (only two paid users because I dislike marketing/sales/customer service). I can do HTML/CSS and basic JS but to be honest I don't really enjoy coding. However, I really like working with computers, utilising ICT software and hardware, and I enjoy making UI/UX/architechtural decisions. I've been considering entering the IT industry when my current teaching contract ends in March 2027.
What sort of skills would I need to develop? Is working in the Japanese IT industry stressful? Is it worth moving to the city for? I feel very satisfied and fulfilled in my current placement/position but I'm considering options because there's no growth/career progression. Looking for ideas on what sort of positions in the IT industry could suit me. Much appreciated!
