Why is advertising in Japan so visually overwhelming and cluttered with text, graphics, and bright colors compared to western advertising? No hate just curious as to why.

I'm guessing advertising is like this to fit as much information as possible into a small area? And perhaps that being normalized over time has led to people finding this form of advertising as trustworthy and legit? I just don't understand how anything would stand out and be noticeable amongst all the noise.

When learning Japanese I found that I struggled most with reading advertisements. My brain seems to just shutdown by being so overwhelmed with information. I don't think I would bode well in major urbanized cities like Tokyo lol.
