Japanese universities with no entrance exam

Hello, hope everyone is good.
I'm currently a Master's student in the field of computer science and I want to apply for kext scholarship PhD program but most of the universities have entrance exams, do you know any universities don't have entrance exam or even easy ones. Please help me.

in general, you have to choose the lab (or a professor) which you have an interest on and you need to show your ability to contribute their academic research projects.
therefore, you thinking that you want to find a lab which is easier to enter is inappropriate.
