If the items you purchase these days seem more expensive, you're not imagining things.

Electric bills are higher. The price for a liter of gasoline or diesel fuel has gone up, with costs being passed on throughout the distribution chain. The raising of the consumption tax on April 1 boosted prices at the checkout counter. And certainly the past several months of inclement weather has caused the prices of certain vegetables and other food items to soar.

Such developments are poised to play havoc with the average household budget. According to data released by the Tokyo metropolitan government in mid-September, the price for a head of lettuce had already soared year on year by 86.5 percent (as opposed to 38.4 percent for cabbage). Other increases (all figures in percent) included beef, 16.2; shrimp, 17.9; tuna, 11.2; salmon, 18.2; imported cheese, 12.2; chocolate, 13.8; and ginger root, 25.5.
