Masami Fujino got his first raise in 20 years recently, but it’s still not enough to let the Tokyo day labourer treat himself to plain McDonald’s hamburgers as much as he used to.

“Last year, I finally got a bit of a raise at one place,” said the 54-year-old, who works for a moving company and in construction. “It brought me up to minimum wage there at last,” 1,072 yen ($8.31) an hour in Tokyo.

Steep price increases on surging raw materials costs are squeezing Japan’s workers, as years of deflation or minimal rises give way to 41-year-high inflation of 4%.
