Moving to Japan for Work as a Fresh Grad – Advice Needed (Indian, AI/ML Background)

Hi everyone,

I'm graduating this week with a Bachelor's degree in Artificial Intelligence and Machine Learning, and I recently received a job offer from a Japanese company in Tokyo as an AI engineer. I'm originally from India and have visited Japan before, but this will be my first time actually living and working there.

I'd really appreciate any advice or insights on the following:

1. What should I look into or prepare before moving to Japan for work?
2. What are some important things to know about working for a Japanese company, especially as a foreigner?
3. Any tips on adjusting to work culture, communication styles, or expectations?
4. Things I should know about daily life (housing, language, banking, socializing, etc.) as a new expat?
5. Are there things I might overlook that are important when relocating to Japan?
6. My Japanese language skills are quite basic—what are some effective ways to study and improve while living and working there?
7. The company is applying for my Certificate of Eligibility (COE)—are there common reasons for rejection, and what are the chances of it getting denied?
   I’d love to hear from anyone who’s made a similar move or has experience living and working in Japan—especially in the tech or engineering space.
