TV has been (or at least had been) at the center of Japanese media and culture for decades so it must have influenced quite a lot. There's also all the other stuff in Japan from magazines to billboards and the signs you see out on the street that are just as wacky and crammed. Japanese design is super crammed in general, and I think some of it comes down to just having less space relative to the number of people and things around, so the design has to be crammed on stuff like billboards and advertisements.
