Some merchants in those countries have stopped. There isn’t a general stoppage of everything.
I just checked and you can still send goods between Japan and the US. There are still merchants selling the exact mentioned camera on eBay that will ship to the US.
Can you source your claim that absolutely no courier is capable of shipping goods into the US? I can’t find anything using google, or on any courier websites.
FedEx does have information about how to correctly fill out the forms for the purposes of tariffs, but does not mention that they will not accept shipments.
I see, that was my mistake then. I was unaware that services like FedEx were still accepting packages. My personal experience was that I have been unable to ship to the US for months because the carrier I use stopped accepting packages, and was under the impression they all had given the number of countries for which this was true and the news coverage I had seen. I wonder why so many countries' postal services have stopped while some couriers like FedEx continue to operate.
There were some temporary stops, but mostly they resolved pretty quickly. I think an issue is that the US requested that tariffs be paid upfront at the sending end and a some couriers aren’t set up for that. Or that they needed time to set it up.
Many of the postal and courier systems that suspended service have since set up the systems they need, and are happily moving packages into the US, but it tends not to make the news.

Here is the exact camera mentioned, offered by a Japanese seller, that will ship to the United States: https://www.ebay.com/itm/317445808304
