Crazy World of Shipping Prices

Thanks, Chris!!
This is important: 
"Unfortunately, with the current global situation and the spread of the coronavirus, Japan Post has suspended services to a high number of countries."

Also, if there is Japan Post Air shipping possible, this remark from Japan Post web reveals the problem:

 "Loading mail items onto airplanes is expected to take considerable time due to the shortage of cargo space caused by the reduction of flights."

There is obviously a shortage of flights to and fro Japan, and some countries can't expect direct delivery. Japan Post remark for my country:

"Delays will be experienced in the delivery of mail items in the country (territory).Items will not be handed directly to addressees."


Also, I noticed one other thing. I could order, "standard Plarail three car train" (that would be a small packet) by Japan Post from PlazaJapan. I suppose they could squeeze somehow small packages on the reduced number of regular flights. But I cannot order anything bigger (like a Plarail set) with Japan Post; bigger packages can be delivered by DHL/FedEx only.
