Planning to move from Indonesia to Japan as a software engineer by 2026 and looking for advice

Hi everyone,

I’m from Indonesia and I’m planning a move to Japan in the next couple of years, so I’d like to get some advice from people who’ve done something similar.

About me:

  • Country: Indonesia
  • Education: Bachelor’s in Computer Science
  • Work: almost 4 months as a software engineer (around 1 year total dev experience)
  • Tech stack: React, Next.js, NestJS

I’ve just started learning Japanese (currently only at hiragana & katakana level) and I’m aiming for at least JLPT N3. My rough goal is to be able to work as a software engineer in Japan by the end of 2026.

Some questions I have:

  1. For someone in IT, what’s the most common visa route for moving from overseas (not currently in Japan)?
  2. Realistically, how much Japanese do I need for day to day life and work? Is it okay to arrive with N3 and improve on the job, or should I try to reach N2 before moving?
  3. Are there any pitfalls people from abroad often underestimate (cost of living, work culture, housing, etc.) that I should prepare for ahead of time?
  4. Any recommended resources, YouTube channels, blogs, or communities for people moving to Japan for work (especially in tech)?

If you moved to Japan for a job, I’d love to hear how your timeline looked and what you wish you had known earlier.

Thank you so much for any tips or stories you can share!
