Need some advice and feedback for a potential move this year

Hi all, as the title suggests, I am expecting to go to a language school this december that will start in January. I am currently in application processes and had a few questions I was hoping I could ask about:

-1. Savings: The website I am using to go through this whole process is Go Go Nihon, their services have been extremely helpful in allowing me to gauge how much I will need once I move but I was curious if there were any helpful insights on this, the website itself quotes a price of roughly 2.3-2.6 million yen per year of study. This would include all of the housing, tuition, etc. is this a realistic amount?

-2. Jobs: I have heard lots about finding jobs as a foreigner but was wondering what the consensus is on this. I have been mostly a bartender and barista most my life with some managing experience as well as a bachelors in business management. Will jobs be easy enough to lock down just to make enough to eat day by day?

-3. Future after school: I plan to study for a year and hopefully longer should finances allow, what does transitioning into normal society look like for a foreign language student? My goal would be to hopefully move into a normal job and start life over there if possible but I have heard many ups and downs to doing so.

Thank you for any feedback I seriously appreciate it!
