A popular topic on television quiz shows is differences in food, speech, and behavior in various parts or Japan. It's not only Eastern vs. Western. It's prefectures vs. prefectures. Hyogo vs. Fukuoka vs. Akita vs. Ibaraki, vs. etc.
This regionalism is amplified by the fact that there aren't, actually, fully national TV channels (except for NHK, with exceptions for the news).
So for example, I live in Aichi, which is between Kantou and Kansai. The channels I have are: Toukai TV, NHK, Chukyo TV, CBC, Meitele and TV Aichi. They are part of broader networks, so for instance, Toukai TV is "mostly" Fuji TV, Chukyo TV is "mostly" Nippon TV, CBC is mostly TBS, Meitele is "mostly" TV Asahi and TV Aichi is "mostly" TV Tokyo. "Mostly" because they all have local programs or even sometimes programs from Kansai instead of whatever might be on air in Tokyo on the corresponding channels.
To give an example of a program I can watch on Chukyo TV, that can't be seen in Tokyo and some other areas: https://www.ytv.co.jp/iinkai/area/index.html (it's produced by Yomiuri TV, which is from Osaka)
