Average monthly wages in Japan adjusted for inflation rose in 2018 for the first time in two years. But critics say the results are skewed.
The release of the preliminary figures by the labor ministry on Friday follows the recent revelation that improper methods were used to conduct the survey.
The data shows workers on average earned 323,669 yen a month, or about 2,940 dollars, including overtime and bonuses. That's 1.4 percent higher than a year earlier, marking an increase for the fifth straight year.
Adjusted for inflation, the figure was up 0.2 percent year-on-year.
Opposition parties say the results cannot simply be compared with data for the previous year as half of the businesses surveyed were replaced last year.
