The employment of farm workers by farm households has been on the increase during
the past two decades in Japan even though most of them still rely totally or largely on family
members’ labor supply. At least a part of the increase can be attributable to an increase in
foreign “technical intern trainees,” but there is no direct information on the nationality of
trainees at the farm household level. This study aims to assess the effects of foreign
trainees in agriculture (and foreign spouses in rural areas) on the employment of farm
workers by farm households in 12 prefectures with higher percentages of foreign trainees or
spouses, applying the Zero-Inflated Poisson (ZIP) model to the microdata from the 2010
Agriculture Census and the municipality-level data on foreign population from the 2010
Population Census.
The ZIP model reveals that the proportion of foreign population in the municipality
population (random-effect variable) has negative effects on the employment of regular farm
workers of both sexes by farm households in Hokkaido and Gunma Prefectures, while it has
a negative effect on the employment of male regular workers and a positive effect on the
employment of female regular workers in Chiba Prefecture. It has positive effects on the
employment of temporary farm workers of both sexes in Hokkaido, Tokushima and Yamagata
Prefectures and negative effects in Ibaraki and Chiba Prefectures. The effects of fixed-effect
variables (the proportions of Chinese and Filipinos in foreign population and the percentages
of women in Chinese and Filipino population) are in both directions depending on the
prefecture and the gender of farm workers. The only relatively consistent effect across
prefectures with a larger number of trainees turns out to be the negative effect of the percentage
of women in Filipino population on the employment of temporary farm workers of both
sexes. This may suggests that Filipino female trainees (and/or spouses) replace Japanese
part-time workers to some extent.
