Thinking of switching universities as a 3rd year student

Hi there! I’m currently a first-year spring intake student in Toyo University, majoring in Global Innovations from the School of International Studies. My degree is taught in english btw.

I’m looking to transfer in my 3rd year to another university in Tokyo that offers degrees taught in english. Currently, I have my sights on Sophia University.

I heard it’s difficult to transfer universities in Japan so I was wondering if anyone has any similar experiences to this? Thank you in advance!
