Maciamo-san, hajimemashite. Comment allez vous?

Funny because some Japanese (few, but yet), actually told me that they were told that only Japan had four seasons. Probably among less educated people, though.
I agree with you that "a few" Japanese believe that "ONLY" Japan has four seasons.
And I would like you to know that majority of the Japanese do not think Japan is the "ONLY"country which has four seasons.
Please, believe me!

Hello, DZIENDOBRY Index-san.

Asking non-Japanese about raw fish is justifiable I think, since eating raw fish is relatively rare outside Japan, especially Europe, Australia or the US.
Yes, I Know. Most of the time they just don't know about our food culture.May be I am a little bit persecution mania, but sometimes I sense a sort of sneer.(Eat raw fish? What a barbarian!)

Here in Brisbane, you can find sushi takeaway shops everywhere. And sushi rolls are very popular among Aussies.
