University in Tokyo, working in Japan & visa gap advice needed

Hey everyone,
I’m currently in Japan studying at a language school and I’m trying to figure out my next move, but I’m a bit confused.
I was thinking of starting university in September 2026, but I also want to understand what my options are if things don’t go exactly as planned.

Some quick info about me:
• Language school student in Japan
• Interested in Business / Marketing
• I’d like to work in Japan after graduating
• I’m taking IELTS soon

Things I’m confused about:
• Which universities in Tokyo are good if you want to work in Japan later, but are not insanely hard to get into?
• If I don’t pass IELTS, what are my options? Are there English-taught programs starting in April, or other alternatives?
• If I finish language school in April 2027 but uni starts in September, how do people usually stay in Japan during that gap? Do some universities help with visas?
• Any opinions on Temple University Japan / Hosei / Rikkyo or some other universities for Business or Marketing?

Any advice or personal experiences would really help.
Thanks!
