Cost of Living Index 2010 International Classification Tokyo is the world's most expensive city in which to live.
Tokyo is the world's most expensive city to live in 282 global locations surveyed at 1 July 2010. While Tokyo is relatively inexpensive items such as alcohol and snuff (ranked 173), is the most expensive for food and health care, and second only to Hong Kong for the accommodation expenses of the household. While Tokyo has always been relatively expensive, this trend has been further strengthened recently, as a result of the Japanese yen, which has gained in value by 18% against the U.S. dollar over the past two years.
