I hate to say this is a strange "win-win" in the end (politically speaking). It'll be a little harder for Japanese companies to take advantage of foreigners, often trafficking them to quite shady working and living conditions with very little pay. This has potential to protect some foreigners from that situation here. Additionally, this looks like a "win" for the anti-foreigner crowd, because "now it's tougher to get a visa here, haha!"
So it's good for foreigners, while also placating the anti-foreigner group.
I know many foreigners here that work in absolutely atrocious working conditions, getting kicked by bosses, seeing crushing death of their coworkers in the factory (and still expected to return to the same unsafe work the next day), tiny wages while living half-dozen people in tiny apartments. It really is sad, and the problem is the companies... not the foreigners.
