At what year level do company workers hit 10million yen salary?

I`m getting my PhD (STEM field) soon and job hunting right now.

But when looking at many of the major Japanese companies the pay seems to start at 300k-400k yen per month for all of them. That`s like half of 10million yen per year when including bonuses. I know its case by case, but do you need to be director level to get a chance for 10million yen salary per year in Japan? Because from what I hear salary raises are really slow.

Is consulting or investment banking only hope if I want to make money?
