The Prefectural Government recently published a report on foreign workers in Kumamoto. If you read Japanese, you can find the report here: http://kumamoto-roudoukyoku.jsite.mhlw.go.jp/library/kumamoto-roudoukyoku/taisaku/gaikokujin/gaikokujinkoyozyoukyou25-10.pdf The screen shots I’m posting (to which I have added English in some cases) show the main findings. In a nutshell, the numbers are up, particularly for so-called “trainees” (技能実習生).
