geography..?

I was just wondering the connection between people and land. I don't know if it's a "geography" topic or not but well...let's see. You know Tokyo and Osaka are two main cities in Japan and generally it is often said that people in Tokyo are conservative and cool while people in Osaka are open-minded and funny. Is it really true?? People's personality changes depending on where they live?? I don't know. But to tell the truth,　I often stereotype people. I think many people do it as well. We have stereotypes about people in other countries,　too like "Americans are friendly, Japanese are smart." or something like that. Maybe it's not completely wrong but actually those are just images. People are all different. We just tend to judge people without knowing them truly. But I still believe that there are cultural or historical backgrounds which make their individuality. I’m from Tokyo and actually I’m not funny and I’m kind of a cold person and I’m not open-minded at all!!! Oh it makes sense!! Tokyo is a big city. I don’t have to socialize with people. That’s why?? Well… maybe this matter is more complicated so I don't really know. Sorry I can't conclude this post!!Ⅰ definitely need to study it more so I'll stop it here today but anyway this is just what I thought.
