Are people in Tokyo less friendly than the rest of Japan?

I know that everyone is an individual and different. But on average, are people in Tokyo less friendly than the rest of Japan? Some people have told me this, I have not spent much time in Tokyo so not sure if this is true.

I have noticed in other countries that people in the commercial capital of that country are sometimes less friendly than elsewhere in the country (eg Shanghai people are less friendly than Beijing, Sydney people less friendly than Melbourne, etc)

Yes,seeing too many people makes you be tired of them and people in a big city like Tokyo have less time and inner reserves to care much about other people.
I have lived some different places including Tokyo and each region had its own character obviously.
But many of Tokyo people are not originally from Tokyo,they are from Kyushu,Shikoku,Kansai or Tohoku or somewher and I feel,just feel they have kept thier original character hidden inside even if they are now Tokyo people.

I wouldn't say that they are less friendly, just that they appear to be quite preoccupied with their lives. They are always in a big hurry (as are people in most big cities) and very business oriented. I suppose these things could cause them to seem less friendly.

If you go to Tokyo and then Osaka, you'll notice a stark contrast - Osakans are friendlier, more cheerful and more likely to strike up a conversation with foreigners. It has happened to me before. Tokyo people are so busy that they don't smile, acknowledge you or they treat you in a dismissing manner.

In general, people in large cities are less friendly than people in more rural towns or small cities, at least to strangers. People in cities complain about not being able to meet people a LOT more than other people, even though there are more people to meet.

So, yes, as a GENERALIZATION, people in Tokyo are less friendly than elsewhere in Japan.

Usually they are thought to be less friendly.

I'm Japanese and even Japanese people say that people in Tokyo are less friendly. But one thing that I want you to know is that there are more crimes in Tokyo, and because of the crimes, people in Tokyo have become cautious. And because they have become cautious, they appear to be less friendly. So it doesn't mean that people in Tokyo are not friendly, but they are just extremely cautious.

Not necessarily less friendly, just a little more busy. But there's also quite a few foreigners.
