How should I pursue or prepare to pursue a master’s degree in Japan as an American citizen living in India?

I am a second year E&TC student studying in a Tier-2 college in Pune, Maharashtra. I wish to pursue a master's degree (postgraduate degree) in some form of electronics engineering from Japan, as I wish to step into some physical engineering field such as network engineering or consumer electronics.

Since I've completed my N5 and N4, I will be giving N3 in the approaching December, and I'm quite confident of passing it since I only fell short of a few marks on my last N3 attempt.

I wanted to ask for some guidance on how I can get into a good engineering school in Japan (ideally in an English-taught electronics engineering course) from my current position. I have a few burning questions that I want answered especially, along with general guidance:

  • Since my first language is English anyways, do I still have to give an English proficiency test?
  • Since I do not live in my country of citizenship, what parts of scholarships/admission could I have problems with?
  • What sorts of internships/publications should I aim for? (asking because I don't have any yet)
  • What are some other qualifications that I should get?
  • What are some English-medium programs that I should look out for?
  • Do any of my_qualifications fall short anywhere in terms of high-school education (GCE A-Levels in Mathematics, Physics, Chemistry, Information Technology, and GCE AS-Level in English (general paper))

Apart from these, I'm open to general guidance. Please do let me know if there's someone here who has already walked the path I'm trying to walk.
