You plug in answers to a series of questions - sort of like a little personality test - and WhatCity returns the city that think most resembles your personality traits.
Here's what it says about why I should be living in Tokyo:
"Admit it - you love the taste of teriyaki bowls, sushi, tempura, and a side of wasabi. Salivating yet? Living in Tokyo lets you treat your tongue to new and exciting experiences. Have fun with all the new tools and gadgets, making your life easier in this technologically-advanced city."Given my love of all things Japanese, this was hardly a revelation!
