I beg to differ. I live in Tokyo. I think it feels great and fun. It's New York, but nice. There are open spaces to the north/south/east/west, within 30 min (depending on which side you live).
Well I have lived in different parts of Japan and I find Tokyo the least inspiring place to be in this country. There's no great landmarks (except if you consider a 600m concrete/steel tower a valuable landmark...), no cool historical places, and this is not a place where I can relax, ever. Even when you reach home you have to live in the smallest apartment ever because it's what's available and affordable there. I agree Tokyo has some interesting aspects (how some quarters differ from one another), but there are too many drawbacks for me to qualify this as "inspiring". I guess it depends on your personality in the end, and what you can relate too. I need to be in a place when I can breathe, and Tokyo feels suffocating in many ways.
