See, I would have figured the "Specialist in Humanities" part of it would not include software development.
I just looked up the definition/qualifications for it and I misunderstood the bit.
I thought it was sub categories. Engineers, who are Specialists in Humanities, who are doing International Services.
But it's more like three different categories. Engineers OR Specialists in Humanities OR International Services.
It seems like they could just move International Services to its own category. (Based on the information in this link: https://portal.jp-mirai.org/en/work/s/highly-skilled-hr/giji...)
