The esoteric reading of minimum wage is it is a accelerationist policy aimed at subsidizing automation.
Though in support of your point, when I went to Korea last year there was a large number of automated kiosks, and I know the minimum wage there is fairly high as well. So, Japan's lack of those kiosks may have to do with a preference towards cash/human interaction in the culture.
Around here (Central Europe, Austria, Germany, Italy too IIRC) I don’t see non-kiosk McDonalds anymore, as they went through the kiosk upgrade in the past few years. Noticeably fewer employees.
I would argue that the job losses to automation would've happened anyway without any discussion of wage increases -- kiosks are cheaper than even below-living-wage workers.
Though I was specifically thinking Sweden.
Good luck getting a that kind of law passed in America though. Far too socialist.
The problem, though, is that there are people who have never not had jobs who nonetheless have opinions on what the baseline job should be. Since they've never had to choose between food and a shitty job, they assume that they can solve the problem by just mandating jobs not be shitty.
Ironically, people who struggle with keeping a job -- are more likely to shoot themselves in the foot by supporting minimum wage increase.
So you will find companies that claim they already pay way above minimum wage but it's just PR.
It is amazing how many commenters on Hacker News do NOT understand basic economic model of supply and demand.
