Need Guidance for studying in Japan to pursue a stable and secure career path for long term living.

Hello, I am 19 years old and I'm looking forward to study in Japan. I'm from India, By the way. I'll keep my name ambiguous.
Ok so, I would like stay here for a long time. I've thought of a path of language school → caregiver training vocational school.

But then, i researched abit and realised caregiving is NOT for me. Maybe IT or any other field might be for me but I'm looking to study in japanese vocational schools that help out students in studying there. And I'll be completing N3 in my country next year around August — September. I'd like to move at the end of 2026 or early as January of 2027. As fast as possible. Please let me know of career paths, scholarships and what I can pursue. I'm still young and I hope I have as much opportunity I am looking forward to…

P.S : I was also looking into dental hygienist, dental assistant, lab technician/clinical testing jobs…those seemed to have appealed to me as well. And IT support or IT Specialist sounds pretty well too. Please help me out!
