Should I try being a Freelancer or a Student in Japan?

Background: I'm Indian. I'm currently in 3rd year of my bachelors college and have plans of going to and settle in japan. I have already started my freelance business of video editing and have plans to scale further as well. I have completed N4, and am preparing for N3 for this december (and have plans for N2 as well next year).

Question: After college, if I wanna move to japan…

• Should I continue in my studies and get masters in japan for the same course (i dont want to tho~); and then apply for the "freelance visa" or smth like that? (Multimedia) (I'll post another post later about choosing uni's and colleges for this but you have some info on this as well, please help)
• If I scale well enough, should I just be japan? As a freelancer? (ik there's some visa issues with that, please tell me about them as well)
• Should I plan my move after doing my masters in my own country?
• or anything similar to this regard…
• Also please tell me how hard is to get a specific visa for this circumstance

I know I'm leaving a lot areas untouched important areas here like the rent/tuition cost, food options, medicines (i get sick easily) et cetera… but if you need any other bg info for your opinion, lemme know and i'll provide them in the replies (or edit here if very imp).

Also my parents got worried after hearing about the nankai earthquake, which will be coming in this decade ig?? idk… If you got any info regarding that, do tell.

Extra ramble↴ (you can skip this if u want)
I may be asking a lot of questions here, i'm sorry, but i dont wanna make a multiple posts regarding singular small topics.
I'm asking this right now cause I feel like I have a bit of time until my college ends and till then I wanna fully prepare for my available options. I know I may be dumb for not researching this well enough on my own but I've always found good & reliable solutions/tips on reddit so i'm counting on that for my future as well 🙂

I know you've probably answered this million times but I couldn't find a clear answer for my situation (in a recent time frame) anywhere else. ごめんね >_< よろしくお願いします 🙏
