How do you like Tokyo?
Yes, I would love to go.  It's the capital city of Japan.
What is the first thing you would do when you go there?
I would probably go to the Kanto region on the southeastern side of the main island Honshu and get Sushi.
But you can get sushi anywhere in the world, there has to be something amazing to try for the first time specific to tokyo, the culture is probably so different then anything in the us.
Have you ever seen Jiro Dreams of Sushi on Netflix?  He has spent like 70 years learning how to make sushi.  The reservations take months.
I guess if you were going for sushi, might as well go for the best. Think there is a big fashion industry there as well, and not to mention all the anime stuff... personally id like to go to some of the auto/car shows they have there.
I'm sure there are some awesome car shows in Tokyo.  It's a Metropolis that was formed in 1943.
