US Covid CDC cards

It�fs looking like all Covid measures will be lifted daily soon(May 8th) but just wanted to confirm something anyway. Is the American CDC Covid card a valid proof of vaccination to bring to Japan?
While I�fm asking a health question.. is there any health forms you have to have in hand? Or is the Covid cdc card and passport enough? Thanks

If anyone can help with this question at least give direction that would be great! We leave in November so it�fs possible we won�ft even need to do anything health form related at that time.

Not and expect. But pretty sure your cdc cards have a digital version.

Inbound rules are changing May 8th. So google that.

If travelling in November, I'd check back later.

I used the Visit Japan Website to pre-register before my arrival in December 2022.

I uploaded my US CDC Covid cards, got my approval and that was it? I might have shown a digital copy of my card at airline check in (I can't remember if they looked at that or just my blue quarantine approval.)

No one in Japan asked to see my card (electric or otherwise) , just the Visit Japan Web blue screen.

I have no idea what the future will hold, I am just speaking from what was required/used in December 2022.
