tokyo the most expensive city in the world

Just in case there were any doubts, Tokyo is indeed the most expensive city in the world.

Hundreds of Americans, largely in finance and banking, are moving back to the United States this summer from Tokyo, often ordered home by stateside managers who don't think Japan's stagnant economy is worth the high cost of maintaining workers there.
For those expatriates still in Tokyo, neither deflation nor that softening housing market has helped much so far. Prices there are still 26 percent higher than in New York.
