Toward a Comprehensive Estimate of the Number of Foreign Workers in Japan
Abstract
Foreign workers are playing an increasingly important role in Japan’s economy, but their total number is undetermined. The Ministry of Health, Labour and Welfare (MHLW) publishes an annual study on the number of foreign workers reported by employers; however, its data is not comprehensive or reliable because it ignores important categories of workers and does not include unreported employees due to the data collection process. In this article, a new method is proposed for providing a comprehensive estimate of the total number of foreign workers based on national census results and data on foreign residents issued by the Ministry of Justice. Estimates of the total number of workers are calculated for the years 2009 to 2016, and compared with the MHLW’s data. The estimates calculated with the proposed method are consistently above the MHLW’s figures over those years, and about 35% higher in 2016. The reasons for the differences are explained, and it is argued that the proposed method enables more credible and realistic data than the results of the MHLW’s annual study.

According to Hennings and Mintz (2018: 112), the size of Japan's foreign workforce has been continuously underestimated, mainly because the Ministry of Health, Labor and Welfare has published incomplete and flawed data.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
