What is the average income in Japan?

According to a 2002 survey conducted by the Ministry of Health, Labour and Welfare, the average monthly salary of people working for companies with more than 30 employees is 387,638 yen, which includes pay for overtime work and bonuses.
When these wages are compared with those of other countries, with Japan indexed at 100, the only country higher is Switzerland at 120.
Germany and Sweden are about 85; and the United States and Great Britain are around 65.
The figures appear to indicate that Japanese workers are blessed, but things are not that simple.
After the bursting of the economic bubble, land prices have fallen considerably, but they are still high enough to make it extremely difficult for most people to buy a home.
And since general prices are higher in Japan than elsewhere, the second highest wages in the world do not necessarily indicate an abundant lifestyle.
