"Japan´s jobless rate would be around 10 percent, compared with the current 5.1 percent, if companies had fired workers rather than cut pay since Japan fell into a recession in 2008. "The monthly average wage in Japan has fallen to 315,294 yen, the lowest level since the government started tracking the data in 1990. Assuming an exchange rate of 90 yen to the dollar, that is roughly $3,500 per month, or $42,000 per year.
Presumably Japan's employers are reducing labor cost to offset the effects of a stronger yen versus the dollar and price competition from Chinese goods on profitability.
One effect that the falling wage levels will have is to reduce the ability of Japanese households to put savings into government debt. This will add some volatility to the prices for Japan's government debt.
Falling wage levels also will make it more difficult for Japan to reduce its dependence on exports as the primary source of GDP growth.
