I'm in Tokyo. I'm from Tokyo

I knew Torino in Italy.<em> I'm not exactly sure what you mean, the word knew indicates the past, similiar to しらない This would mean that you knew Torino before, but you now forgot it...</em>

<em>the following but in the next sentence though indicates that you wanted to say don't know, </em>

<em>so the correct sentence would be: </em>I don't know Torino in Italy...

...but I have been to Roma, Italy. 

I dont know soccer in detail,Torino is the famous city that "Juventus" and "Torino Football Club",right? I don't know soccer in detail. Torino is the city with the famous football clubs "Torino Football Club" and "Juventus Turin", right?  

<em>I hope I could be of help to you. If you have any questions, please ask</em>
