Looks like our wallets can get one card lighter soon.
According to this Nikkei article we can soon get a 2 in 1 card combining the two.
Honestly though I feel they should just force foreigners to get the Mynumber card from the start since it’s tied to your visa anyways. I like that everyone has the same type of my number card, don’t want mine to be different but we’ll see how this shakes out.
