Everyone has a my number, it's needed to do your taxes for example. But the government wants everyone to get a plastic my number ID card and use it for multiple services including replacing your health insurance card. But using one card for various services is seen as a privacy risk. I don't remember the details but it doesn't seem legal to force people to get one and use it, so they've been offering incentives like coupons for stores. Meanwhile, from what I passively understand from news, there's been issues like information sent to the wrong person so it's difficult politically to push for it more. I personally didn't get the card because for foreign residents it expires when your permission to stay expires and I didn't want the hassle of getting a new one each time. Now I live in Europe and I have a similar digital ID and it's quite nice to be able to do virtually any procedure online, although once you apply, stuff that took 30 minutes or 1 week in Japan takes 3 months here.
