Cost of living in tokyo, osaka and fukuoka?

Hi there! Saw a job posting and was thinking about trying, but a bit unsure about the wage vs living there, so would appreciate if someone helped!
Currently researching more too about japan, culture, etc to see if it is the best for me.

These are the informations so far:
– 231k starting salary which includes 45k allowance for classes (they teach japanese, tho I do plan on starting to learn now regardless)
– need to live at most 2km away from the studios, which depends on the place I would be assigned to (tokyo, osaka or fukuoka)
– they give 150k yen in the beginning to help moving, but I am unsure whether that is taken from the salary (probably, right?)
– single, ok with cooking for the whole week (freezing portions n such) to make things cheaper
– I dont eat a lot (usually around half the amount someone usually eats)
– ok with less space

Cant think of any other info that is pertinent, but will write it here if it comes to mind or if someone asks
