If you want cheap tuition, then you should go to a public university in China. The general tuition fee is 530 thousand yen. But it's hard to get in.
If you want to get in, it is a private university, and the tuition is similar. Mainly according to the different majors. Ranging from 800,000 yen to 3 million yen.
Private universities in Tokyo are relatively easy to enter:
Tunghai University
Dadong Culture University
Richeng University
J.F. Oberlin University
I hope it helps you.
Feel free to consult if you have any questions.
