I find it kinda funny that even "smartest", most capable models often have a very hard time going beyond surface-level, top-of-mind associations, when faced with creative tasks.

Of course, a "Japanese Minimal Poster" has a sakura and a stylized flag of Japan, duh

A human designer would probably think that "Japan -> sakura" and "Japan -> Japanese flag" are way too obvious, too banal, too stereotypical, and, most importantly too boring. And then they would probably sit for a while and try to think of something fresher and less clichéd.

But AI has absolutely no problem with going with the cheesiest, most overused trope.
