Could I chain digital nomad visas + language school visas?

I am currently in Japan on a digital nomad visa. I'm trying to figure out the best way for me to stay longer. I am a self employed 30 year old from America.

My understanding is that I can apply for another digital nomad visa 6 months after my current visa ends.

My understanding is that you can go to language school for 2 years on a student visa?

Could I get a language school visa for 6 months -> then go home and apply for a digital nomad visa -> come back to japan for 6 months -> rinse and repeat for 4 years?

Is there a rule to stop me from doing this? Would immigration allow this? Does the the two years of language school have to be consecutive? I do see language schools with a 6 month option.
